Rough-toothed Dolphin
Steno bredanensis
Summary 5
The rough-toothed dolphin (Steno bredanensis) is a species of dolphin that can be found in deep warm and tropical waters around the world.
Description 6
Rough-toothed dolphins are usually seen swimming in schools of 10-20 individuals, although groups of 50 or more have been reported. They are sometimes seen cruising along at high speed, with their beaks at the surface and their dorsal fins above the water, for fairly long periods of time. They live in deep offshore waters, and knowledge of their range comes more from reports of strandings than sightings at seas. Rough-toothed dolphins have large eyes, which may enhance their vision when they make deep dives. Females are sexually mature at about the age of 10, and males at about 14. The maximum life span is thought to be about 32 years.
