Sea butterfly pseudoconch The group is known within the fossil record from shells of those groups within the clade that mineralized. [ 12 ] [ 13 ] These carbonate shells are a major contributor to the oceanic carbon cycle, making up as much as 12% of global carbonate flux. [ 3 ]
Sea butterfly pseudoconch The group was originally referred to as the Pseudothecosomata Meisenheimer, 1905, although this name is invalid under the ICZN and thus is no longer recognized. [ 1 ] Instead its three families are categorized within the superfamily Cymbulioidea, which is itself part of the clade Thecosomata.
The superfamily Cavolinioidea is the most speciose group of sea butterflies. They belong to the suborder Euthecosomata. [1] Sea butterflies (thecosomata) are pelagic marine gastropods, so called because they swim by flapping their wing-like parapodia.
By doing so, the animal effectively flies through the water. The sea butterfly uses a high angle of attack of approximately 45-50 degrees to generate lift, and it beats its wings 4 to 10 times per second. It propels itself using a version of the clap and fling mechanism described by Torkel Weis-Fogh in small insects such as thrips.
The family Cavoliniidae is a taxonomic group of small floating sea snails, pelagic marine opisthobranch gastropod mollusks. [ 1 ] This family is part of a larger group which is commonly known as the sea butterflies because they swim by flapping what appear to be small "wings".
The butterfly fauna of Indochina includes Indo-Burmese genera with a species-richness (a count of species within the genus) generally distributed from Assam to Sundaland (Sunda Islands), genera with a strong centre of species-richness in western China and the eastern Himalaya, genera with their greatest species-richness in Sundaland west of the ...

Clione limacina, known as the naked sea butterfly, sea angel, and common clione, is a sea angel (pelagic sea slug) found from the surface to greater than 500 m (1,600 ft) depth. [ 2 ] [ 3 ] It lives in the Arctic Ocean and cold regions of the North Atlantic Ocean .
