Also known as
Sand Tiger Shark, Spotted Ragged-tooth Shark.
The Grey Nurse shark was the first shark species in the world to be protected in 1984, under the
Fisheries and Oyster Farms Act. Current population estimates on the east coast of Australia are now estimated to be between 1146 and 1662. Queensland alone saw a decrease of a whopping 77% over a 40 year period.
In 1994 they were listed as 'Critically Endangered' in NSW, and internationally in 2008 under the
International Union for Conservation of Nature and Natural Resources
(IUCN) Red List.
Up until the 1980's, Grey Nurse Sharks were misunderstood, and were thoughtlessly killed due to their fierce appearance.
The main reason nowadays for the huge decrease in numbers is commercial fishing. Despite the laws surrounding the Grey Nurse Sharks protection, they still get accidentally caught up in drop-lines and other line fishing equipment.
Another contributing factor is the relatively slow growth rate and reproductive cycle. Females only reach sexual maturity at around 9-10 years of age and males only around 7 years. Combine this with a pupping rate of roughly every 2 years, and you start to see the problem.
