Clione limacina, aka Sea Angel, approximately 1.5 inch.
These molluscs are small pelagic gastropods (pteropods), of the suborder Gymnosomata. The foot has evolved into "wings" that are used for locomotion. It always stays adrift in the water column and never touches the bottom. Clione feed mainly on Limacina helicina aka Sea Butterfly and other planktonic organisms. The buccal apparatus is comprised of three pairs of buccal tentacles that grasp the shell of the Limacina. When the prey is in a proper position, with the shell opening facing the radula of Clione, it deploys the chitinous hooks and grasps the prey, extracting the entire body out of the shell and then swallows it whole.
