Caribbean Roughsharks hail from the Caribbean Sea and Gulf of Mexico, and they tend to live at depths of between 1400 and 1600 feet-- so no where near the surface! They have blunt noses, two dorsal fins, and no anal fin. They also have really unusual coloration-- darker grey or brown over most of their body, but light grey on the fins and head, with dark blotches.
Because they live at those depths, they aren't studied a whole lot. We do know that they are slow moving predators, and they feed on small invertebrates and fish.
These Sharks are most commonly seen when they get caught up in fighting nets. They show up occasionally as bycatch for bottom trawls.
