cuttlefish, also known as cuttlefish, whose real name is Myzus chuatsi, which is also known as cuttlefish, cuttlefish or cuttlefish, belongs to the order Cephalopoda of mollusca.

unlike squid, squid has a boat-shaped calcareous hard sheath.

The biggest feature of squid is that it will use "ink jet" as an escape method when it encounters a strong enemy, and wait for an opportunity to leave, so it has names such as "squid" and "cuttlefish". There are pigment vesicles in the skin, which will change color and size with the change of "mood". Lay eggs on wood chips or seaweed in late spring.

cuttlefish larvae refer to relatively small cuttlefish.
