Sand tiger sharks (Carcharias taurus), also called grey nurse sharks, can reach a maximum length of 330 cm but are usually smaller. These coastal sharks are rare in the Gulf of Maine, and they are listed as Vulnerable on the IUCN Red List of Threatened Species. At least one study (Musick et al. 1993), found that sand tiger shark populations declined by as much as 75% during the 1980s as a direct result of the commercial shark fishery along the Atlantic coast. The Southwest Atlantic Subpopulation is listed as "Critically Endangered."
Like many sharks, the sand tiger shark is especially vulnerable to even moderate levels of exploitation because of life history and reproductive traits. Female sand tiger sharks usually give birth to 2 pups after an 8-12 months gestation period.
The species is unique amongst sharks insofar as it is believed to be the only shark that can inhale and store air in its stomach in order to maintain neutral buoyancy.

Anglers who fish for marlin in the Western Atlantic had [...]
