What is the purpose of “sperm” in sperm whales?
I'm just curious, what is the purpose of "sperm" in sperm whales?
Sperm in sperm whales actually refers to a waxy substance found in their heads called spermaceti. Its purpose is still not fully understood by scientists, but it is believed to aid in echolocation and buoyancy control for the whale. Would you like me to find more information on this topic?
