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 1.2 m (4 ft) and 40 kg (90 lb) (Maui's dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 long tons; 11 short tons) (the orca or killer whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, eating mostly fish and squid. The family Delphinidae is the largest in the Cetacean order, and evolved relatively recently, about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals, and their often friendly appearance and seemingly playful attitude have made them popular in human culture.

A graceful Indo-Pacific Bottlenose Dolphin is shown swimming in the clear aqua waters off Port Stephens in NSW, Australia. Around 90-120 dolphins live permanently in these waters and are much-loved by locals and visitors alike. The dolphin is viewed side-on and its whole body can be seen from snout to tail. Half its body is out of the water. Next to the dolphin there are two other dolphins from its pod swimming underwater. These grey dolphins get their name from their short round snouts that look a bit like a bottle. They also have a broad triangular dorsal fin in the middle of their backs. The water in the photo is a beautiful clear aqua green colour.
