Its coloration ranges from dark gray on the back with a very distinct boundary, giving the impression of a cape, to lighter gray or whitish on the belly.

The spinner dolphin inhabits warm and temperate waters across all the world's oceans, including the waters off the Canary islands, where it is regularly observed offshore.

The spinner dolphin is a pelagic species that inhabits both coastal and offshore waters, often in areas of shallow banks and sheltered bays.

Spinner dolphins are social animals that live in groups ranging from about 20 to 100 individuals, and they are very active and playful with one another. They are also known to follow boats and schools of fish.

The spinner dolphin primarily feeds on fish, squid and shrimp.

After a gestation period of about 11 months, female dolphins give birth to a single calf, which they nurse for several months. As adults, spinner dolphins can live up to 40 years.

The main threats faced by dolphins include pollution, bycatch in fisheries and habitat destruction.
