Already equipped with an impressive sonar system, new research reveals that dolphins have an extra ability that evolves as they mature in the space where their baby whiskers once were. The super sense may help them navigate and find hidden food sources.
Dolphins' sonar ability, known as echolocation, is fairly legendary in the animal kingdom. This ability is so accurate that the mammals, which are technically whales, can use it to distinguish between a golf ball and a ping-pong ball underwater based on the densities of the two objects. But that's not where the creatures' impressive abilities end.
