I will wager money that their names translate to things like:
Big nose
Funny tail
Horny boy
Big mamma
Deep swimmer
Not just amusing, but also useful. By correlating individual behaviors and physical features with names, we might be able to unlock dolphin language! Which would be incredible!
Great idea. We humans were named after many characteristics. Jobs, what we see when the child is born, what kinds of personality we want our children to have, etc.
