[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 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.
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 ...
The sea slugs can move toward prey or mates by using their cerata, the thin feather-like "fingers" on its body, to make slow swimming movements. [ 10 ] [ 22 ] They are known to prey on the dangerously venomous Portuguese man o' war ( Physalia physalis ), the by-the-wind-sailor ( Velella velella ), the blue button ( Porpita porpita ), and the ...
Most batoids have a flat, mantle-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.
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]
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.
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 is classified as a pteropod.
