Fish Ceilidh
Catfish make sounds by shifting the vertebrae in their spine.
Seahorses knock together the bones in their skull.
Rockfish make low frequency noises by special muscles
located near their swim bladder. Grunts. In herring,
the bladder is connected to the digestive system,
so there’s a buzz when air is pushed from the anus:
they sound like Russian subs.
