The Sand Tiger Shark or Carcharias taurus is found in coastal waters worldwide. They are often seen in and around sandy beaches. This species of saltwater fish goes by several different names including the Spotted Ragged Tooth Shark, Blue Nurse Sand Tiger and the Grey Nurse Shark. Reaching just over 11 feet (3.4 meters) these sharks will feed on crustaceans, squid, skates and small bony fish. Despite its fearsome looking teeth, this shark is relatively harmless and slow moving. You can learn a little more about the Sand Tiger Shark in the video below from the Discovery Channel.
The Sand Tiger Shark has a couple odd characteristics that distinguish it from other species of shark. They actually have the ability to breath air from the surface which allows it to float near the surface with ease. They also have small eyes that have no eyelids. Not only this, but they also practice intrauterine cannibalism, which means that during pregnancy the developed embryo will feed upon its siblings!
This shark is kept in many aquariums throughout the world and does very well in captivity. Unfortunately, like so many other creatures in the ocean, this species is listing as vulnerable on the International Union for Conservation of Nature Red List.
