Distribution
Tope sharks are widespread, found in waters from the UK and Ireland, Australia, South Africa, and on both coasts of North and South America. They undergo long-distance migrations, often associated with feeding and reproduction events.
Habitats
These sharks prefer coastal waters, often found in depths ranging from 10 to 550 m, though they can inhabit deeper areas. They tolerate a wide range of water temperatures, often preferring warmer waters.
When and Where to See
Tope sharks are most often seen in the summer months, particularly around dawn and dusk.

Identification Guide
H3 Physical Characteristics
Tope sharks have a slender, torpedo-shaped body, a long, curved tail fin, and typical coloration ranging from grey to black. One distinction from similar species is the lack of a white edge on the dorsal fin.
Culinary
Tope meat is tender, with a mild flavor, often used in fish and chips in the UK. However, there are sustainability concerns due to their vulnerable status.
Additional Information
These sharks are mainly carnivorous, with a diet consisting of fish, squid, and crustaceans. They have few predators as adults, though juveniles may be preyed upon by larger shark species. There have been historical reports of attacks on humans, though these are rare.
