The Grey Nurse Shark also known as the sand tiger shark or spotted ragged-tooth shark, is one of four species belonging to the family Odontaspididae. The species has a large, rather stout body and is coloured grey to grey-brown dorsally, with a paler off white under belly. Reddish or brownish spots may occur on the caudal fin and posterior half of the body, particularly in juveniles. The species has a conical snout, long awl-like teeth in both jaws (with single lateral cusplets), similarly sized first and second dorsal fin and an asymmetrical caudal fin. Grey nurse sharks grow to at least 360 cm total length. The grey nurse shark is a slow but strong swimmer and is generally more active at night.
Grey nurse sharks are often observed just above the sea bed in or near deep sandy-bottomed gutters or rocky caves, in the vicinity of inshore rocky reefs and islands. The diet of the adult grey nurse shark consists of a wide range of fish, other sharks, squids, crabs and lobsters.
Grey nurse sharks have a broad inshore distribution, primarily in subtropical to cool temperate waters around the main continental landmasses.

Shark bites can be quite lethal to humans, especially the 10 most dangerous shark species are considered and can launch unprovoked attacks from humans: - Great white shark - Bull shark - Tiger shark - Sand tiger shark - Blacktip shark - Bronze shark - Spinner shark - Blue shark - Hammerhead shark - Whitetip shark The bite by a shark is one of the most basic fears of humans, but the number of deaths caused by shark attacks is very low: in 2015 there were 98 attacks by sharks and in 6 cases the attack resulted in a fatal end for humans. In 2016 there were 107 attacks by sharks and in 8 cases the attack resulted in a fatal end for humans.

In 2022, there were a total of 108 shark attacks in the USA.
Conversely, however, 100 million sharks were killed by humans. http://www.zeit.de/2016/37/haie-toetung-tierschutz-surfer The risk of being bitten by a shark varies greatly from region to region, with most attacks occurring in Florida, Australia and South Africa. Please be careful not to go into the water with bleeding skin wounds, heed bathing warnings from the authorities and be very careful when using surfboards, as sharks can easily confuse the boards with seals and harbour seals. After shark bites, always call a doctor or / and the rescue service as soon as possible, as heavy bleeding can be life-threatening.
