Sperm Whale
The world’s largest toothed predator makes the loudest animal sounds on Earth. Sperm whales create powerful clicks using their massive spermaceti organ. These clicks reach an incredible 230 decibels. Their huge, box-shaped heads process returning echoes during deep dives to find squid. They hunt in total darkness at depths reaching 3,000 meters below the surface. Their clicks serve double duty. Besides finding prey, these sounds can actually stun fish and squid before capture.
