The first in situ habitat observations and images of the Caribbean roughshark, Oxynotus caribbaeus Cervigon, 1961 (Squaliformes: Oxynotidae)

摘要

In situ observations and photographs of the Caribbean rough-shark, Oxynotus caribbaeus Cervigon, 1961, are reported for the first time from four widely separated localities around the tropical western Atlantic, including multiple records over an 8-yr period from a single locality off Roatan, Honduras. These records document an extension of the known geographic, bathymetric, and temperature ranges of the species to include southern Florida and the western Caribbean Sea, over a depth range of 218 to 579 m, and in water as warm as 16.39°C.
