Cuban dogfish live in the western Atlantic, from North Carolina in the United States to Argentina, encompassing Cuba, the Gulf of Mexico, Hispaniola, and southern Brazil.

They are most commonly spotted at depths from 196 ft to 1246.72 ft, where continental shelves and uppermost slopes are located.



This shark feeds on benthic invertebrates like shrimp and squids, as well as small fish.


These sharks form large schools to travel in.


Female Cuban dogfish give live birth to a litter consisting of 10 pups on average, though 18-23 pups are not uncommon. They become sexually mature when about 19.4 inches long.

Interactions with humans

While humans don’t consume this shark, they are caught for the vitamins and oils provided by its liver. Despite this, the shark’s population isn’t at risk, with the IUCN classifying it as “Least Concern” or “LC”.
