Bottlenose Dolphin
These intelligent marine mammals produce rapid clicks through a fatty structure in their forehead called the melon. They can hear returning echoes through their lower jaw. Bottlenose dolphins use this skill to find fish and squid in murky waters where visibility is poor. They adjust their click frequency based on what they’re looking for. Small prey requires higher frequencies while distant objects need lower ones. This precision targeting system works even in rough seas with crashing waves.
