Q. Where do cuttlefish bones come from?

Answer

A cuttlebone is not a bone but rather the interior shell of a cuttlefish a little mollusk that resembles a squid. The cuttlefish's cuttlebone which is gas-filled aids in regulating the fish's buoyancy in the water. Crab and shrimp are their preferred foods but they have also been observed eating fish. They have an interesting beak that has been compared to a parrot.
