Bottlenose dolphins are probably one of the best-known species of animals. They have a length of around 10 to 14 feet and a streamlined body with a large fin at the top. Their skin is gray and smooth without long hair like most mammals.

Some look small, and others are much larger and heavier, since their range is between 150 and 650 kilograms, with males having larger body dimensions than women, so there is sexual dimorphism.

One of the characteristics of bottlenose dolphins is their thick and notorious snout that give them their odd colloquial name.

Other features of bottlenose dolphins are the flippers and their powerful caudal fin.
