As carnivores, their diet consists of fish, crustaceans and squid. They are socially friendly creatures known to have aided humans multiple times, especially during shark attacks.

They are also popular choices for captivity and breeding, although the rate of survival is often low. The most popular species of dolphins are Killer Whales as featured in the film Free Willyand the Bottlenose Dolphins.

Shark vs Dolphin These two intelligent creatures both inhabit the same vast ecosystem of the ocean but what is the difference between a Shark and a Dolphin? The simplest way to explain it is that a Shark is a fish and a Dolphin is an aquatic mammal. Sharks use gills to breathe underwater while Dolphins have to resurface every now and then in order to inhale fresh oxygen through their blowholes before diving again.
