Seafish releases a burst of ink from their barbs whenever they are threatened. They were once hunted by poachers for their ink, but poachers lost interest when cheap ink became widely available.

A Seafish uses the pressure of water it swallows to shoot toxic quills all at once from all over its body. The poisonous barbs all over its body are highly valued as ingredients for making traditional herbal medicine.
