Atlantic spotted dolphin

The Atlantic spotted dolphin (Stenella frontalis) lives in warm temperate and tropical waters of the Atlantic Ocean, from Cape Cod and West Africa south to Brazil and including the Gulf of Mexico, the Azores and the Canary Islands. Adult males reach about 2.26 meters and 140 kilograms and females about 2.29 meters and 130 kilograms, and the species undergoes a striking change in coloration with age, from the plain gray white of newborns through a speckled juvenile phase to the heavy dark and white spotting of mature adults on both back and belly. It hunts cooperatively in groups, mostly at night, taking small fish, bottom dwelling invertebrates and cephalopods such as squid at depths of up to about 60 meters.
