Most bats live a nocturnal life, hence, they need an efficient mechanism to move around in the dark. Bats use a technique called echolocation to navigate and hunt their prey. Echolocation works when the bat emits sounds of variable pitch, which bounce off obstacles or prey, before bouncing back to the bat. Analysis of this can reveal details about the bat’s environment or potential prey.
Sperm whales use a similar technique when hunting. They emit soundwaves which can reflect off the surrounding, revealing the details of the environment. Explore more about echolocation or other interesting topics by registering at BYJU’S.
