Question

which two animals use echolocation? bats and humans bats and dolphins dolphins and humans dolphins and butterflies

Explanation:

Echolocation is a biological sonar used by animals to detect objects. Bats emit high - frequency sounds and use the echoes to navigate and find prey. Dolphins also use echolocation, emitting clicks and interpreting the returning echoes to understand their environment. Humans do not naturally use echolocation (though some can be trained to use a form of it in a very limited way, it is not a natural biological ability like in bats and dolphins). Butterflies do not use echolocation.

Answer:

bats and dolphins
