Oxynotus caribbaeus is thought to be a slow-moving predator of small benthic organisms.

Adult males reach a maximum size of 50 cm (1.6 ft) in length and the females are thought to grow even longer, although none has been examined.

Its first dorsal fin is inclined forward, is very long and thick, and triangular in shape.

[3] Oxynotus caribbeaus is found in the western Atlantic Ocean, also near the bottom of the Gulf of Mexico and the Caribbean Sea.

[4] However, sightings of the Caribbean roughshark have happened in the waters off of the Bahamas, Honduras, and Venezuela.

[4] The sizes of these shark pups are thought to be 20 to 21 cm long, for both male and females examined.

As uncommon as it is found as a bycatch, it can still have a negative impact due to the small population observed in the inshore waters.
