The whitesaddled catshark is a species of catshark, and part of the family Scyliorhinidae. It is found on the upper continental slope of the western central Atlantic Ocean, off the coasts of Honduras, Panama and Colombia, between latitudes 22° N and 9° N, at depths between 274 and 457 m.

The southern sleeper shark or Whitley's sleeper shark is a deepwater benthopelagic sleeper shark of the family Somniosidae found in the southern Atlantic, Indian, and Pacific oceans. It is known from depths of 400 to 1,100 m. Its length is up to 4.4 m (14 ft). It feeds primarily on cephalopods, especially the colossal squid, and fish; its stomach contents also less commonly contain remains of marine mammals and birds. Based on its generally sluggish nature and the speed of its prey, it is thought to be an ambush predator. A 3.6-m-long female caught off the coast of Chile had a whole southern right whale dolphin in its stomach. This dogfish is sometimes taken as bycatch in the orange roughy and Patagonian toothfish fisheries; whether this poses a threat to the species is currently unknown.
