This shark is a highly prized food item in the western northern Pacific, off Ghana and off India and Pakistan where they are caught by fishing trawlers, although they are more commonly caught with a fishing line. This species belongs to the Odontaspididae family. Sand Tiger Shark Size: The average length in male sand tiger sharks grows up to 2.2 – 2.6 m while the females grow 2.3 – 3.0 m. These sharks length grow up to the length of 3.2 m and weight about 155 kg. 2020 National Geographic Partners, LLC. In the western Indian Ocean, the shark ranges from South Africa to southern Mozambique, but excluding Madagascar. [2] Many sand tigers are caught in shark nets, and then either strangled or taken by fishermen. The sand tiger shark's description as Carcharias taurus by Constantine Rafinesque came from a specimen caught off the coast of Sicily. Range Sand tiger sharks are found in shoreline habitats to depths of about 625 feet (190 m). Snout and mouth of sand tiger shark, showing protruding teeth and small eyes. [16] Females mate only every second or third year. The male regularly approaches the female in "nosing" behaviour to "smell" the cloaca of the female. The same applies to the bottom-living sea catfish (Galeichthys feliceps), a fisheries resource off the South African coast. They are voracious predators, feeding at night and generally staying close to the bottom. They have a flattened, cone-shaped snout and a distinctive, oblong tail with a notched, upper lobe that is significantly longer than the lobe below. Under this FMP, it has been illegal to land (both commercially and recreationally) this species or any parts (fins, meat, jaws, etc) on the Atlantic coast of the U.S. since 1997. The sand tiger is categorized as vulnerable on the International Union for Conservation of Nature Red List. Threats to Survival The sand tiger shark or Grey nurse shark (Carcharias taurus) is a species of shark that inhabits coastal waters worldwide.It lives very close to the shorelines and beaches of North America, hence the name, sand tiger shark. "The behavioural and genetic mating system of the sand tiger shark, "Reproductive periodicity, localised movements and behavioural segregation of pregnant Carcharias taurus at Wolf Rock, southeast Queensland, Australia". [12] Off South Africa, sand tigers less than 2 m (6.6 ft) in length prey on fish about a quarter of their own length; however, large sand tigers capture prey up to about half of their own length. Agassiz's name was used until 1961 when three palaeontologists and ichthyologists, W. Tucker, E. I. the striped weakfish (Cynoscion guatucupa). Most of Sand tiger sharks only produce two pups at one time. In the western Pacific, it has been sighted in the waters around the coasts of Japan and Australia, but not around New Zealand.[1]. In Argentina, the prey items of sand tigers largely coincided with important commercial fisheries targets. The name sand shark comes from their tendency to migrate towards shoreline habitats, and they are often seen swimming around the ocean floor in the surf zone; at times, they come very close to shore. [2], The majority of prey items of sand tigers are demersal (i.e. The “sand” portion of its name comes from the shark being seen around shallow waters and close to shore. For example, the scientific classification of the shortfin mako shark goes like this: Kingdom: Animalia (all animals) Despite this, they are a docile, non-aggressive species, known to attack humans only when bothered first. Strong interest of the male is indicated by superficial bites in the anal and pectoral fin areas of the female. However, there are several other differences that are probably more reliable: Adult sand tigers range from 2 m (6.6 ft) to 3.2 m (10.5 ft) in length and 91 kg (201 lb) to 159 kg (351 lb) in weight. Despite its name, it is not related to the tiger shark Galeocerdo cuvier. During the day, they take shelter near rocks, overhangs, caves and reefs often at relatively shallow depths (<20 m). [13] Stomach content analysis indicates that smaller sand tigers mainly focus on the sea bottom and as they grow larger they start to take more benthic prey. Sharks and their Relatives Scientific Names 26 Terms. In 1977, Compagno and Follet challenged the Odontaspis taurus name and substituted Eugomphodus, a somewhat unknown classification, for Odontaspis.
