Spinner Shark Facts

The Spinner Shark names a medium-sized species of requiem shark that has become quite popular with spectators for its acrobatics.
Its common name comes from its unique feeding strategy since the species typically feed on schools of small fish. When it attacks its prey, the Spinner Shark swims vertically through the school with a spinning motion.
The species has also become popular for its tendency to leap completely out of the water at times which makes for a really beautiful sight.
Relative to its size, this amazing animal represents one of the swiftest and most gregarious predators in any ocean. The fish does not typically pose a threat to humans unless the individual is in a feeding frenzy, however.
The IUCN currently lists the species Near Threatened, and may soon raise that to Threatened.
