6 Extraordinary North American Reptiles

We sincerely hope that you enjoy this article about 6 Extraordinary North American Reptiles. Reptiles fascinate many people around the world, perhaps giving us a glimpse into the past, at a time when dinosaurs ruled the world. Of course, these 6 Extraordinary North American reptiles represent just a small handful of the numerous species in the region. But we hope that reading and learning about these will help to whet your appetite to learn more.

Leaping Lesbian Lizard

Leaping Lesbian Lizard Facts

• Leading off this article about 6 Extraordinary North American Reptiles is one that leaps out at you, the aptly-named Leaping Lesbian Lizard.
• Firstly, the unusual term serves as the popular name for a particular New Mexico Whiptail Lizard. But what sets it apart is the fact that it was produced through the inter-breeding of two distinct native species of lizard.
• This astonishing lizard resulted from the mixing of the Little Striped Whiptail and the Western Whiptail. The hybridization of these species produces sterile males, however. But, the resourcefulness of Nature did not stop there.
• That’s because, the species achieved parthenogenesis, which is a type of asexual reproduction. This allows the resulting all-female population to reproduce. Therefore, the unusual lizard actually evolved into a separate species capable of reproduction.
• Furthermore, in fact, this combination of inter-species hybridization and parthenogenesis isn’t unique. It exists in other species within the animal kingdom. That’s due to the fact that the process exists as a reproductive strategy in several other known species of whiptail lizard.
• Finally, the astounding Leaping Lesbian Lizard also holds yet another distinction. This one, however, has nothing to do with any physical aspect of the amazing creature. That’s because this phenomenal reptile currently represents the official state reptile of the state of New Mexico.

Leaping Lesbian Lizard Physical Description

Most notably, the amazing Leaping Lesbian Lizard constitutes a small-to-moderate sized variety of lizard. That occurs due to the fact that the majority of individuals attain a total length measuring between 6.5 – 9.1 in (16.5 – 23 cm). Quite obviously, sexual dimorphism does not appear in this species.

In addition, its natural coloring typically presents as an overall brown or black. However, seven pale yellow stripes also from head to tail. Further, numerous light spots often occur between the stripes. The majority of individuals also have a white or pale blue underside, with a blue or blue-green colored throat.

Additionally, the body of the Leaping Lesbian Lizard develops a distinctive shape. That appears as distinctly slender, while the tail of the awesome reptile grows comparatively long. In fact, this particular shape, in combination with its coloring pattern, represents an evolutionary adaptation for camouflage in its native habitat.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Squamata
• Family: Telidae
• Genus: Cnemidophorus
• Species: C. neomexicanus

Leaping Lesbian Lizard Behavior

Furthermore, like most other whiptail lizards, the Leaping Lesbian Lizard evolved as diurnal. Therefore, it is far more active in the daylight hours. It also evolved as entirely insectivorous in nature. In addition, it remains wary, energetic, and fast moving, frequently darting for cover if approached.

But, its reproductive methods separate it from most related types of lizards. When this reptile reproduces, the mother-to-be lays up to four unfertilized eggs. This action most commonly occurs in the mid-summer part of the year. These precious few eggs then typically hatch approximately eight weeks later. 

Despite reproducing asexually, and being an all-female species, the Leaping Lesbian Lizard still engages in mating behavior with other females of its own species. Interestingly, a common theory suggests that this behavior stimulates ovulation. This belief occur due to the observed fact that those who do not mate do not lay eggs.

Leaping Lesbian Lizard Distribution, Habitat, and Ecology

Not surprisingly, the truly fascinating Leaping Lesbian Lizard  evolved as native to a particularly arid environment. That highly specific range includes the southern United States and also northern Mexico, in North America.

However, even within these two regions, the Leaping Lesbian Lizard has specific areas it inhabits. As a result, in the United States it only appears in New Mexico and Arizona. Meanwhile, in Mexico, the species only lives in the area of Chihuahua.

The New Mexico Whiptail Lizard, as it is also known, also lives in a rather wide variety of semi-arid habitats. These regions include grassland, rocky areas, shrubland, or mountainside woodlands, proving its adaptability.

Eastern Diamondback Rattlesnake

Eastern Diamondback Rattlesnake Facts

• Our next choice for inclusion in this compilation of 6 Extraordinary North American reptiles is the amazing Eastern Diamondback Rattlesnake.
• Most notably the name of Eastern Diamondback Rattlesnake applies to a reptile that remains a highly venomous species of pit viper. Further, the dangerous animal evolved as endemic to only a specific region of the world. This area consists solely of the southeastern United States.
• In addition, this dangerous but magnificent rattlesnake also holds another impressive status. That’s because it ranks as the heaviest venomous snake in either North America or South America. Despite its great weight, however, the animal does not qualify as the longest.
• For a variety of reasons, the IUCN currently lists it as a species of Least Concern on its Red List of Threatened Species. This status currently remains under review, however. This reconsideration occurs due to ongoing changes in conditions within the endemic range of the snake.
• Finally, estimates place its current numbers at only 3% of what they once were. Habitat loss and highway mortality, coupled with a low reproductive rate form the primary factors in its decline. But now, climate change may soon threaten the Eastern Diamondback Rattlesnake, as well.

Eastern Diamondback Rattlesnake Physical Description

Firstly, the amazing Eastern Diamondback Rattlesnake constitutes a physically quite imposing reptile. It holds this claim due to its sheer massiveness, for a venomous reptile. However, variations in size do occur. This holds true partly due to the fact that this amazing creature displays a slight degree of sexual dimorphism.

In its case, this principle presents itself in terms of overall size. That’s because the male typically attains a slightly greater length and weight than the female. Nevertheless, the difference remains quite small. Therefore, the two genders are usually considered to be of the same approximate size when measurements are discussed.

As a result of this, a typical length for this incredible reptile equals roughly 5.5 ft (1.7 m). Furthermore, the typical mature adult generally weighs about 10 lb (4.5 kg). Yet, exceptional specimens occasionally reach great lengths, equaling as much as 7.8 ft (2.4 m). In addition, most of the exceptional-sized individuals are male.

The Eastern Diamondback Rattlesnake also presents a striking image in terms of color patter. That’s because this most commonly consists of shades of brown, yellow, gray, and olive. Additionally, this pattern develops overlaid with a series of 24-35 black or dark brown diamond shapes. This serves as the source of he common name.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Squamata
• Family: Viperidae
• Genus: Crotalus
• Species: C. adamanteus

Eastern Diamondback Rattlesnake Distribution, Habitat, and Ecology

Although the Eastern Diamondback Rattlesnake evolved as endemic to the southeastern United States, it only appears in a limited portion of it. As a result, its natural range only extends along the coastal plain. More specifically, that runs from eastern North Carolina to southeastern Louisiana.

Yet, it does inhabit some portions of the range in greater numbers than others. Due to this, the increasingly rare animal appears to be most numerous in Alabama and Georgia. Quite unfortunately for those who love Nature, it now appears to be extinct in North Carolina and Louisiana, however.

Further, its most notable feature nevertheless remains its relative toxicity. A typical bite produces 3-4 times the amount of venom needed to kill an average human. Antivenom is readily available in most medical facilities throughout its range, however. Therefore, attacks usually only become fatal if left untreated.

The dangerous but impressive animal also remains quite adaptable, and will inhabit a wide range of habitat types. These include pine forests, sandhills, coastal hammocks, and most types of swampy areas. The Eastern Diamondback Rattlesnake also typically resides within burrows previously excavated by other animals.

Texas Horned Lizard

Texas Horned Lizard Facts

• Our third choice for inclusion in this compendium of 6 Extraordinary North American Reptiles is the impressive Texas Horned Lizard.
• First of all, the incredible animal with the descriptive common name truly remains a remarkably astonishing creature. The amazing reptile also forms one of the 14 known species of spike-bodied reptiles that evolved within its native range of habitation.
• Collectively, many people also know the different species within this group by several other common names. These other alternate names include the horned toad and the horned frog. However, the impressive group itself remains known by the name of horned lizards.
• Furthermore, this truly amazing animal historically played a key social role among some groups. That’s because some Native American peoples traditionally considered this animal to be sacred. Due to this, the various tribes often included the animal in much of their art.
• Finally, some humans previously kept the Texas Horned Lizard in captivity, as exotic pets. Quite fortunately, that practice is now illegal. Very sadly, and for various reasons, the distinctive species now holds a Threatened status with the IUCN, on its Red List of Threatened Species.

Texas Horned Lizard Physical Description

Although all species of horned lizard remain comparatively diminutive in size, the Texas Horned Lizard stands out. That holds true due to one specific fact. That’s because, in addition to its other unique attributes, this fascinating variety of lizard ranks as the largest of the species in its area.

The remarkable lizard also displays a moderate degree of sexual dimorphism in regards to size. The females attain a length of as much as 4.5 in (11.4 cm). Meanwhile, the smaller male reaches up to 3.7 in (9.4 cm) in length. The bodies also develop far more round in shape than most lizards. 

Furthermore, its coloring displays a distinctive pattern that serves it well in terms of camouflage. This consists  of a mottling of various shades of brown, gray, and black. The protruding horns of the Texas Horned Lizard also form surprising extensions of its skull and have a composition of solid bone.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Squamata
• Family: Phrynosomatidae
• Genus: Phrynosoma
• Species: P. cornutum

Texas Horned Lizard Distribution, Habitat, and Ecology

Most notably, the Texas Horned Lizard evolved as native to a specific area of North America. To be precise, that area of habitation includes Kansas, Colorado, Arizona, Texas, and northern Mexico, in the United States. Humans have also introduced it into Georgia, Florida, and the Carolinas.

Further, despite its rather fearsome appearance, the creature remains remarkably docile. Wild individuals will sit calmly in one’s hand. However, this level of docility obviously presents dangers for the lizard. In addition, individuals rarely bite, unless they feel themselves to be directly threatened.

Furthermore, the impressive animal evolved a diet very similar to many related species. As a result, it remains entirely insectivorous and feeds primarily on harvester ants. However, it will also feed opportunistically on a variety of other insects, especially if its preferred prey remains scarce.

Additionally, the amazing Texas Horned Lizard also developed a highly unusual defense mechanism. That’s because individuals can project an aimed stream of blood from the corners of the eyes, and from the mouth as well. Finally, this blood is also mixed with a chemical to make it extremely foul-tasting.

Tiger Rattlesnake

Tiger Rattlesnake Facts

• Sitting in the fourth spot on this list of 6 Extraordinary North American Reptiles is the awesome Tiger Rattlesnake.
• Perhaps the most noteworthy fact about the remarkable rattlesnake remains the high level of danger it represents. That holds true due to the fact that the animal represents the most dangerous of known varieties of rattlesnake. This level of danger occurs regardless of sheer size.
• Furthermore, the quantity of venom injected with a bite equals significantly less than that of similar species. Yet, its the nature of the toxin that makes it so perilous. That’s because the venom contains a powerful mix of neurotoxins and mycotoxins which often leads to muscle death.
• Quite unfortunately for it, the endemic range of the species ranks as somewhat restricted. Furthermore, even within that range, its own nature serves as a limiting factor to its potential spread. That occurs due to the fact that its habitat requirements restrict its population to very specific regions.
• Finally, despite inhabiting such a restricted range, its numbers appear to be stable. As a result, the IUCN lists this snake as a Species of Least Concern on its Red List of Threatened Species. Nevertheless, given the specific nature of its habitat needs, it remains highly vulnerable to the effects of climate change.

Tiger Rattlesnake Physical Description

Firstly, the impressive Tiger Rattlesnake classifies as a type of pit viper. Secondly, it also qualifies as a somewhat smaller than average one. Further, like many species of reptiles, this animal displays the physical trait of sexual dimorphism. In its case, the males typically attain a slightly larger size than the females.

Neither gender attains an impressive physical size, however. Additionally, lengths vary significantly between individuals. That’s because mature adults average between 18 – 36 in (46 – 92 cm) in length. Yet the average length equals about 24 in (61 cm). Also, weights rarely exceed 1 lb ( 0.45 kg), and average much less.

Perhaps the most distinguishing physical feature of the remarkable rattlesnake is the head of the reptile. This develops in a highly rectangular shape. It also forms quite small in proportion to body length, compared to related species. Meanwhile, the rattle on its tail develops much larger than others, in relation to body size.

In addition, its basic coloring also varies greatly among individuals. Most present combinations of either an orange-brown or bluish gray. Black bars also show across the body, hence the common name of the Tiger Rattlesnake. Like all pit vipers, individuals also possess heat-sensing organs on each side of the head.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Squamata
• Family: Viperidae
• Genus: Crotalus
• Species: C. tigris

Tiger Rattlesnake Distribution, Habitat, and Ecology

The astonishing Tiger Rattlesnake evolved as solely endemic to specific portions of North America. More specifically, it appears only in the region of the state of Arizona, in the United States, and southern Mexico. Yet more specifically, within that range, the snakes roam at altitudes ranging from sea level to 4,806 ft (1,465 m).

The small but powerful reptile usually inhabits regions of rocky desert canyons, bajadas, and foothills. This highly adapted species also remains primarily terrestrial. Nevertheless, some individuals will occasionally perch in low vegetation. Furthermore its periods of activity also vary somewhat, according to the seasons.

Just as all other known snakes, this rattlesnake evolved as a carnivore in nature. Quite understandably, given its size, individuals primarily prey on a variety of small mammals. Yet, it distinguishes itself in yet another manner. That’s because, unlike most snakes, it will hunt by both ambush and active stalking equally.

Finally, considering its own level of lethality, its own predators remain few. But the few it does face includes hawks and eagles. By nature, the Tiger Rattlesnake can be easily annoyed and remains quite aggressive. The major threat it faces is human expansion into its endemic territory, just like many other species.

Mexican Mole Lizard

Mexican Mole Lizard Facts

• The fifth of our choices to include in this listing of 6 Extraordinary North American Reptiles is the amazing Mexican Mole Lizard.
• Most notably, despite its common name, the truly astonishing small creature represents neither a mole nor a lizard. However, this extremely unique and rare animal does hide a small secret. That’s due to the fact that it actually constitutes a very odd type of small reptile.
• Furthermore, this incredibly unique creature also represents one of only 180 known species placed in its genus. In addition, each and every one of them have one thing in common. That’s because, in point of fact, none of the members of the genus classify as either lizard or snake.
• Yet the surprising animal sets itself apart from even the great majority of its fellow members of the genus in one specific way. That holds true because it remains one of only four known species in this small genus to display a certain trait. That’s because the others do not possesses any legs at all.
• The Mexican Mole Lizard also qualifies as what scientists call an amphisbaenian. Most unfortunately, being exclusively a subterranean dweller, the remarkable animal is rarely seen. Finally, the average lifespan of this incredibly interesting animal measures only about two years.

Mexican Mole Lizard Physical Description

First of all, the breathtaking species known as the Mexican Mole Lizard remains a rather diminutive variety of reptile. That’s because individuals attain a maximum known length of roughly 9.5 in (24 cm). In addition, the width of the small bodies also typically measures only about 0.25 in (6 mm).

Additionally, its coloring represents yet another remarkable physical trait, further setting it apart. That occurs due to the fact that the fascinating creature typically develops predominantly varied shades of pink. This distinctive appearance occurs due to a complete lack of skin pigmentation.

Further, the amazing Mexican Mole Lizard possesses only two, very short legs. However, Nature placed these appendages directly behind the animals’ small head. Five toes with sharp, comparatively long claws also appear on each of the feet. Its skin also grows rather closely segmented, like an earthworm.

In addition to its other traits, the remarkable little lizard also evolved as oviparous in nature. Furthermore, the female of the fascinating species generally lays between 1-4 eggs. Finally, the extremely interesting small reptile exhibits no recognizable degree of the trait of  sexual dimorphism.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Squamata
• Family: Bipedidae
• Genus: Bipes
• Species: B. biporous

Mexican Mole Lizard Distribution, Habitat, and Ecology

The fabulous Mexican Mole Lizard appears to only be endemic to portions of the Baja Peninsula, Mexico, in southern North America. However, currently unconfirmed sightings also place its range from the extreme southwestern portions, through Big Sur, and into to the Western Cape Region.

In addition, the natural habitat of this remarkable reptile remains predominantly dry to desert regions. But, it also appears to require the presence of plentiful shrub vegetation. Quite unfortunately, to date, this incredible animal has not shown itself to be particularly adaptable to other habitat types.

In all regions it inhabits, members of the species typically prefer to remain below ground. There, the creature lives under the many layers of vegetation. This it does for a specific reason. That’s because this location provides it with at least a measure of protection from potential predators.

Additionally, the resourceful Mexican Mole Lizard constructs lengthy and elaborate systems of tunnels beneath the ground. It also evolved as carnivorous in nature and will prey on virtually anything small and soft enough to swallow. Unless disturbed, it usually remains close to its burrows.

American Crocodile

American Crocodile Facts

• The final entry into this compilation of 6 Extraordinary North American Reptiles is the fascinating American Crocodile.
• Perhaps most notably, the American Crocodile represents a particular species of crocodilian found in the Neotropics. It also goes by the somewhat cumbersome scientific name of the Crocodylus acutus. 
• In addition, the remarkable creature also holds yet annother distinction. That’s due to the fact that it appears to be the most widespread of the four extant species of crocodile from the Americas.
• Within the boundaries of its greatest area of concentration, the distribution of the American Crocodile remains extremely limited. This range includes only Puerto Rico and the southern half of Florida.
• Finally, this rather powerful and highly dangerous if provoked animal currently has an estimated population of 2,000 individuals. For the moment, the IUCN lists it as Vulnerable on its Red List of Threatened Species.

American Crocodile Physical Description

Like all crocodilians, the fascinating American Crocodile developed as a quadruped, with four short, splayed legs, and a long, powerful tail. Furthermore, it also possesses a thick, scaly hide with rows of ossified scutes running down its back and tail.

In addition, the snout of the impressive reptile also grows elongated and includes a remarkably strong pair of jaws. The eyes further develop covered by nictitating membranes for protection, along with lachrymal glands, which produce tears.

The nostrils, eyes, and ears grow situated on the top of its head, so the rest of the body can be concealed underwater for surprise attacks. As a larger species of crocodile, some males reach lengths of as much as 20 ft (6.1 m) and weigh in excess of 2,000 lbs (907 kg).

However, on average, mature males of the American Crocodile remain more in the range of  13 ft (4.1 m) in length and weigh about 880 lbs (400 kg). As with many other species, sexual dimorphism is present. As a result, females develop smaller, rarely exceeding 12 ft (3.8 m) in length.

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Crocodilia
• Family: Crocodylidae
• Genus: Crocodylus
• Species: C. acutus

American Crocodile Habitat

As recently as 1970 experts placed the population of the American Crocodile appeared highly threatened. Estimates placed its population at no more than 200 individuals. The habitat of the powerful crocodile consists largely of coastal areas.

Individuals may also be found in river systems but have a tendency to prefer some level of salinity in the water. This results in the species congregating in brackish lakes, coastal swamps, lagoons, even cays, and small islands.

Some other crocodiles also have a tolerance for salt water, due to salt glands underneath the tongue. But the American Crocodile remains the only species other than the saltwater crocodile to commonly live and thrive in saltwater.

Like any other large species of crocodilian, this creature continues to be potentially dangerous to humans. However, it does not appear to be a very aggressive species. That holds true due to the fact that attacks on humans rarely occur. 

American Crocodile Distribution and Ecology

Populations of the American Crocodile occur across a realtively wide swathe of the region. Populations exist from the Atlantic and Pacific coasts of southern Mexico to as far away as Peru and Venezuela, in South America.

This amazing species remains most prevalent in the United States, in North America, however. The powerful reptile also occasionally occurs on many of the Caribbean islands. But it remains unclear if this forms part of its natural range.

The well-known reptile also constitutes one of the larger known crocodile species. This species also has a more V-shaped snout compared to other large crocodiles that usually have a slightly wider snout. But the evolutionary reason for this is still unknown.

Despite its large size, this incredible reptile does not commonly prey upon large animals as most large crocodilians do. Fish, reptiles, birds and small mammals appear make up the majority of the diet of most individual specimens.

Nevertheless, exceptions do occur. That’s because, on occasion, large mammals such as deer and domestic animals do get taken. Finally, its dietary habits in coastal regions remain poorly studied, at least for now.
