Yes, dolphins are carnivorous marine mammals.
These marine mammals are known to eat a wide variety of foods from fish, crustaceans, squid and cephalopods to marine mammals.
While smaller dolphins tend to stick to a diet of fish and other small prey larger species such as the killer whale and false killer whale (both belong to the dolphin family) will hunt and attack larger prey such as seals, sea lions, marine birds, penguins, sharks and even large whales.
Dolphins belong to the cetacean species which also includes whales and porpoises.
The cetacean species is broken down into one of two suborders known as toothed whales and baleen whales.
Dolphins belong to the toothed whale suborder of which there are currently around 40 known species of dolphin in existence today.
In order to capture their prey dolphins use a number of different team oriented (as well as solo) hunting methods.
One of these strategic team oriented hunting methods involves a group of dolphins surrounding and circling their prey in order to block their prey from escaping and force them into a small dense ball.
Once they have their prey trapped together and isolated the dolphins will swim through the ball one or two at a time and pick off the fish as they lay bundled together and helpless.
Another method often used by coastline dolphins is to try to force their prey into a corner, against a wall or into a shallow riverbank near a river bed or the coast line where the water is too shallow to swim effectively order to prevent them from making an easy escape.
While all dolphins have teeth not all species use their teeth to their full advantage.
Some species use their teeth to tear apart their prey while others use their teeth only to grab onto their prey and will swallow their food whole.
