Dolphin is an intelligent water mammal with a long snout that is like a beak, two flippers, a dorsal fin, and a tail fluke. A dolphin has a pointed snout and steamlined body. Dolphins are closely related to propoises and whales.
They have smoothe skin with a rubbery texture and combination of black, white, and gray colors.
Although a dolphin looks like a fish, it is a mammal. They can't breath in water like fish so they have to come to the top of the water to breath. Like whales, dolphins breathe through the blowhole which is their nose. They expel and inhale air through the blowhole.
Each dolphin has almost 100 teeth and the teeth are used for catching food, but not for chewing because dophins swallow the food whole without chewing.
They are found in all oceans of the world from the tropics to the temperate regions. The common dolphin is found in warm coastal waters (the Mediterranean Sea and the Black Sea). Hector's dolphin lives in the offshore water of New Zealand. Spotted dolphins live in deep ocean waters. Peale's dolphin is native to cold waters of the Atlantic and Pacific off the southern part of South America.
They feed mainly on fish and squid.
Dolphins are small, playful whales. They grow about 7 to 10 feet long. Dolphins are larger than porpoises.

*They are known for their intelligence. They are graceful swimmers and can be trained to perform impressive tiricks.
