Dolphins Have Individual Names Called Signature Whistles

Dolphins have a sophisticated communication system that includes individual 'names' called signature whistles. Each dolphin develops a unique sound pattern within their first year of life that serves as their personal identifier. These signature whistles are learned, not inherited, and remain consistent throughout their lives. Other dolphins can 'call' a specific individual by copying their signature whistle, similar to how humans call each other by name. Mother dolphins teach their calves their signature whistle, and dolphins can recognize the signature whistles of family members and pod mates even after years of separation. Research has shown that dolphins respond specifically when their signature whistle is played back to them, but not to other dolphins' whistles. This naming system helps dolphins maintain social bonds in their complex aquatic environment where visual cues are limited.
