These dolphins are small and easy to identify, due to the head which is evenly sloped. It also lacks a beak at the end of its snout. On their tails and along their back is a bluish black color. Their belly is white with a dark color on the lower jaw and snout. Dusky Dolphins can grow to 6 1/2 feet long and can weigh anywhere from 150 to 187 pounds. The males and females look about the same size, though the males have a more curved dorsal fin. Dusky Dolphin have about 24 to 36 pairs of teeth which are pointed and very small. Usually, the upper jaw will have two sets less teeth than the bottom jaw. These dolphins are very social, and live in pods of about 20 to 500 members.
Dusky Dolphins are very acrobatic and jump out of the water very often, such as in the picture above. They feed on shrimp, squids, various fish and anchovy. It is hard to get a total or around the amount of number of the Dusky Dolphin species, though it is known that many of them die, getting caught in fishing nets or illegal harpoon hunting. Right now though they aren't in danger of becoming extinct.
