Around 30 species of whales and dolphins are found on the Great Barrier Reef. And there’s nothing fishy about that because both dolphins and whales are warm blooded, air breathing marine mammals, not fish.
The Bottlenose dolphin is one of the most commonly seen species on the Reef. These social creatures tend frequently accompany tour boats, surfacing and playing in the wake of the ship and sometimes spectacularly leaping out of the water.
They live in pods that can range from 10 - 1000 dolphins and hunt in groups, using geo-location to locate their food. Like all other mammals, they breathe oxygen to survive. They must surface every few minutes, especially when in a high speed chase.
Other dolphins often spotted on the Reef include the Spinner dolphin, aptly named for its tendency to leap and spin out of the water, the Indo-Pacific humpback dolphin, Australian humpback dolphin, Australian snubfin dolphin, and pan-tropical spotted dolphin.
