Dolphins give each other names and use them for life
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Bottlenose dolphins develop unique signature whistles within the first few months of life — personal acoustic identities equivalent to names. Other dolphins learn and use these whistles to address specific individuals, and a dolphin will respond to its name even when called by a dolphin it has never met. Researchers found that dolphins retain these name whistles for at least 20 years. This is the clearest evidence of non-human animals using arbitrary sound labels to refer to individuals.
Naming is considered a uniquely human social technology, tied to language and identity. Discovering dolphins do it independently rewrites our understanding of what names actually are.
