The S. Bredanensis or rough-toothed is a species of dolphin that can be found in deep warm and tropical waters around the world.
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 lb. 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.
The distribution and population of the Rough-toothed dolphin is poorly understood.
They inhabit the Pacific, Atlantic, and Indian Oceans, and in the Mediterranean Sea, in warm temperate to tropical waters, with occasional reports from cooler environments.
Rough-toothed dolphins can also bee seen regularly in locations stretching from the Windward Islands to Cape Verde, but only a small handful have been seen in Azores and Madeira.
Live sightings are almost universally made far off-shore, beyond the continental shelf, in water at least 1 kilometre (0.62 mi) deep.
Most of the research activity concerning the Rough-toothed dolphin has been directed in the eastern Pacific, where a population estimate of 150,000 was obtained by researchers in the 1980s.
Fossils belonging to the genus Steno are known from Europe and date to the early to mid-Pliocene.
In the Mediterranean Sea, the species was once considered to be visiting from North Atlantic until recent findings revealed that there is a small but resident population in the eastern part of the sea.
