We all sing like fish

Nerve controls for singing, chirping and croaking use the same ancient network.

No matter how off-key you might be, you’re still singing like a nightingale. Or a fish.

NERVY FISH Studies of how the nervous system develops in larval midshipman fish (here 8 to 10 millimeters long) have revealed nerve circuitry similar to that controlling the vocal muscles in frogs, birds and mammals.
