Clione limacina, common name Naked Sea Butterfly, Sea Angel, and Common Clione, is a sea angel found from the surface to greater than 500 m in depth.,[2][3] It lives in the Arctic Ocean and cold regions of the North Pacific and North Atlantic Oceans. It was first described by Martens in 1676 and became the first gymnosomatous (without a shell) "pteropod" to be described.[4]

Subspecies[edit]

  • Clione limacina australis (Bruguière, 1792)[5]
  • Clione limacina limacina (Phipps, 1774)[5]

Distribution[edit]

Clione limacina is found in cold waters of the Arctic Ocean, North Pacific Ocean and North Atlantic Ocean.[6] A closely related species, Clione antarctica, is found in Antarctic waters.

Clione limacina

Description[edit]

There are two races that differentiate in body length.[7] Northern race lives in colder water and its size is 70–85 mm.[7] The size of the southern race is 12 mm.[7]

The neurobiology of this pteropod has been studied in detail.

Ecology[edit]

Clione limacina inhabits both the epipelagic and mesopelagic regions of the water column.[5]

Feeding habits[edit]

They feed in a predator-prey relationship only on the sea butterflies of the genus Limacina: on Limacina helicina and on Limacina retroversa.[3][7] 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.[8]

It can survive one year without food.[9] Under such exceptional starvation in the laboratory the length of slugs have changed on average from 22.4 to 12 mm.[9]

Life cycle[edit]

Sexes are separate but are seldom conspicuously different externally, simultaneous hermaphrodites yet self-fertilization is prevented due to various morphological, physiological, or behavioral mechanisms.[5] Generally, marine gastropods shed their eggs.[5]

Clione limacina is a prey of planktonic feeders, such as the baleen whales,[7] which historically led to sailors naming it "whale-food".[10] Some fishes are also its predators.[7]
