The rough-toothed dolphin or Steno bredanensis is a species of dolphin that can be found in deep warm and tropical waters around the world.

The species was first described by Georges Cuvier in 1823. The genus name Steno, of which this species is the only member, comes from the Greek for ‘narrow’, referring to the animal’s beak — which is a diagnostic characteristic of the species. The specific name honours van Breda, who studied Cuvier’s writings. There are no recognised subspecies.

The rough-toothed dolphin or Steno bredanensis is a relatively large species, with adults ranging from 6.9 to 9.3 ft. in length, and weighing between 198 and 342 lbs; males are larger than females. Its most visible characteristic feature is its conical head and slender nose; other dolphins either have a shorter snout or a more visibly bulging melon on the forehead.

As the common name for the species implies, the teeth are also distinctive, having a roughened surface formed by numerous narrow irregular ridges. Steno bredanensis have been reported to have between nineteen and twenty-eight teeth in each quarter of the jaw.

The rough-toothed dolphin or Steno bredanensis flippers are set back further along the body than in other similar dolphins, although, at sea this dolphin may be confused with spinner, spotted and bottlenose dolphins. The dorsal fin is pronounced, being from 7.1 to 11.0 ins. in height.

The animal’s flanks are a light gray, while the back and dorsal fin are a much darker gray. Older Steno bredanensis individuals often have distinctive pinkish, yellow, or white markings around the mouth and along the underside.

Although details of  the rough-toothed dolphin or Steno bredanensis diet are sketchy, the stomach contents of stranded dolphins have included such fish such as silversides, sauries, houndfish, smelts, cutlassfish, and various squid and octopuses. Predators on rough-toothed dolphins are thought to include killer whales and sharks.
