The tentacles and suckers of squid come in many shapes and sizes. Some suckers look and act like a suction cup, while others have evolved into pointed hooks that dig into prey. Here, three tentacles from three different squid species are compared. At the top is the Pacific flying squid, in the middle is the angle squid, and at the bottom is the ram’s horn squid.
