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, an artifact of the "smile" of their mouthline, and seemingly playful attitude have made them very popular in human culture.

After staying awake for many hours or days at time, humans and other mammals alike are forced to sleep, not because the body asks it, but because the brain inevitably calls for a shut down of the conscious psyche, in order to replenish and function properly when awake. Dolphins, however, have been found to have [...]

Dolphins are absolutely amazing creatures, smarter beyond whatever you might think, and with a heart of gold.
