The Clionidae are a family of sea angels, which are a group of pelagic marine gastropods. They resemble angels , complete with flapping "wings", hence their common name. They are gelatinous, mostly transparent pteropods , and they only have shells in their embryonic stage.
[5] [4] It is not yet clear whether the sea angel uses its swimming appendages as 'rowing paddles' or as 'wings'. [6] However, cold water sea angel C. antarctica likely accommodates drag-based force production for several reasons: (1) Low aspect ratio for C.antarctica causes deleterious lift-drag ratios. (2) High angle of attack typically ...
The Notobranchaeidae, or "naked sea butterflies", are a taxonomic family of floating sea slugs, specifically under the subclass Opistobranchia, also called "sea angels". [1] [2] Similar to other Pteropods, these pelagic marine heterobranch gastropod mollusks [3] are holoplanktonic. [4] [5]
Clione antarctica is an important component of polar ecosystems.It preys upon Limacina antarctica [1] It is itself eaten by the medusa Diplulmaris antarctica. [4] C. antarctica has a large lipid storage capacity: up to 5% of its wet mass. [5]
Clionoidea is a taxonomic superfamily of sea slugs, specifically naked (i.e. unshelled) pteropods, marine opisthobranch gastropod mollusks in the clade Gymnosomata. [1] They are sometimes called "sea angels" or "naked sea butterflies" along with the other superfamily in the Gymnosomata. They can be found anywhere from the surface to a depth of ...
Spongiobranchaea australis is a species of sea angel, a form of sea-slug plankton. It has a partially transparent body with small "wings" that it uses to swim in its habitat. It has a partially transparent body with small "wings" that it uses to swim in its habitat.
The Cliopsidae, common name sea angels, are a taxonomic family of small, free-swimming sea slugs, pelagic marine opisthobranch gastropod mollusks in the order Opisthobranchia. As is the case in all gymnosome pteropods , these sea angels lack a shell except during an early embryonic stage.
Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed their pectoral fins into broad flat wing-like appendages. The anal fin is absent. The eyes and spiracles are located on top of the head.
