Description

The tope shark or soupfin shark is a slender shark of the family Triakidae reaching about 195 cm. The body is greyish above and white below, with juveniles showing black markings on the fins. The large mouth carries small, blade-like teeth, and the lower lobe of the tail is almost as long as the rest of the caudal fin. The species occurs worldwide in cool to warm-temperate waters and is highly migratory, forming schools that are sometimes segregated by size and sex. It is ovoviviparous with 6 to 52 pups per litter. Because of heavy fishing and slow reproduction the tope is assessed as Critically Endangered; its flesh is regularly eaten.
