As previously mentioned, the sand tiger is not related to the tiger shark. It is also not related to the nurse shark, despite its other common name, the grey nurse shark. Its scientific name – Carcharias taurus –means “bull shark”, but it is also not closely related to the bull shark. It belongs to the order of mackerel sharks, which includes the great white, the mako, the basking shark, and the thresher shark.
Though it looks fearsome, it is actually quite an easygoing shark, and attacks on humans are rare. They are commonly found in commercial aquariums, where they do quite well compared to many other species of sharks, though they can have difficulties in tanks that are not large enough to accommodate them.
