CEPHALOPODS

This class of molluscs is the most intelligent and mobile, and displays a remarkable diversity in size and adaptations for predation, locomotion, camou􀆪age and communication. highly advanced and organised, these invertebrates are exclusively marine􀇦dwelling animals that have suckered tentacles and arms, camera like eyes and colour shifting skin. They range in size from the giant squid at 20 metres (the world’s largest mobile invertebrates) to the smallest, pygmy squids (Idiosepius), which are barely an inch long.
