Sound is ultrasonic, meaning humans cannot hear it without special equipment designed to detect it. It’s interesting to note that mice have evolved to use these incredibly high frequencies to communicate covertly from predators.

We are very thankful for these adorable creatures, as research continues on how rat whistles can help humans treat speech-related conditions.

Yes, dolphins have sound-based names that are personal to them.

They communicate with each other using these whistles or “names,” usually to find out each other’s locations. Researchers have also noticed that they use some whistles more than others, further corroborating the theory that bottlenose dolphins use the sound to call specific group members, such as kin.

This remarkable phenomenon needs further research, especially since they also whistle in captivity (for which there are no callers).

However, it is an interesting phenomenon, and at the time of writing – humans and dolphins are the only species with specific names that call others!
