Dolphins and Porpoises Skulls Replicas Models

Shop for Dolphins and Porpoises Skulls Replicas Models – Dolphins are marine mammals closely related to whales and porpoises. There are almost forty species of dolphin in 17 genera. They vary in size from 4 ft. and 90 lbs. They are found worldwide, mostly in the shallower seas of the continental shelves and are carnivores, eating mostly fish and squid. The family Delphinidae, the largest in the Cetacean order, evolved relatively recently, about ten million years ago during the Miocene.

Porpoises are small cetaceans of the family Phocoenidae. They are related to whales and dolphins. They are distinct from dolphins, although the word porpoise has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible difference between the two groups is that porpoises have shorter beaks and flattened, spade-shaped teeth distinct from the conical teeth of dolphins.
