This is the familiar dolphin that we are used to seeing in movies or TV shows. As the name “common” suggests, it is found all around the world, in tropical and temperate waters. The common bottlenose is the largest of the beaked dolphins, measuring 6.6 to 13.1 feet (2 to 4 meters) long.

Even though they live underwater, dolphins are mammals and have to emerge every so often for air. They do not breathe automatically as humans do — they must voluntarily swim to the surface to breathe. For this reason, they can never fall completely asleep. They keep one side of their brain active so that they can remember to breathe.

The diet of the bottlenose dolphin consists of a wide variety of fish, eels, squid and shrimp, which it swallows whole. It hunts and navigates using echolocation, which is the process of releasing a sound that bounces off surrounding objects and echoes back to the dolphin. It can then determine the location, size, shape, distance and speed of those objects.

Bottlenose dolphins are highly intelligent and social animals. They often interact with humans. They have even been trained for military uses, such as finding sea mines. They have also been known to help fishermen by driving fish toward the fish net, and eating the fish that escape from the net.
