Dolphins

• Their skills: they have the largest brains and can recognize faces

In general, male dolphins are larger than females and both genders can travel at speeds 29 km/h (18 mph) for short distances. These pretty creatures use their conical shaped teeth to catch fast moving prey. Mother Nature gave them a well developed hearing which is so strong that they can survive even if they are blind. Their skin has a layer of fat to keep them warm in the cold waters.

Dolphins are social creatures that usually travel and hunt in groups, called ‘diddle’. Their diet consists of fish and squid, but other species of dolphins, such as the killer whale, prefer large mammals, such as seals.

They are often kept in captivity because they can be easily trained to perform tricks and impress people – and yes, they turned out to be one of the most intelligent animals out there, especially because they have a large brain, unlike other animals that have similar body sizes, a fact confirmed by Lori Marino, a dolphin expert at Emory University.

In addition, animal experts say that dolphins can recognize people’s faces as well as their own appearance and communicate with each other.
