Location:

Feeding:
The feeding process of Clione limacina is somewhat extraordinary. The buccal apparatus consists of three pairs of buccal cones. These tentacles grab the shell of Limacina helicina. When the prey is in the right position, with its shell opening facing the radula of Clione limacina, it then grasps the prey with its chitinous hooks, everted from hook sacs. Then it extracts the body completely out of its shell and swallows it whole.It can also survive up-to a year without food.
