It is a known fact that there is continuous darkness deep down inside the sea. Did you ever thought about how sperm whales hunt in that darkness? Do they hunt in a similar way a bat does? Yes, these whales hunt like bats — by using echolocation to find their prey, a new research says.
Feeding mainly on squid, the sperm whale is considered to be the largest toothed whale in the world that dive deep into the seas in search of their preys. But, only a little has been discovered on the hunting behavior of these gargantuan marine mammals. Hence, not much is known about their prey detection behavior.
