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.
