Like almost all heterobranchs, blue dragons are hermaphrodites and their male reproductive organs have evolved to be especially large and hooked to avoid their partner's venomous cerata. [8] Unlike most nudibranchs, which mate with their right sides facing, sea swallows mate with ventral sides facing. [25]
Pteraeolidia ianthina is a sea slug, an aeolid nudibranch in the family Facelinidae. [ 2 ] [ 3 ] It is known as a blue dragon , [ 4 ] a name it shares with Glaucus atlanticus and Glaucus marginatus .
Nudibranchs are often casually called sea slugs, as they are a family of opisthobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups that are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic Sacoglossa and the colourful Aglajidae, are ...
Glaucus is a genus of small blue pelagic sea slugs.They are aeolid nudibranchs, [1] ranging in size from 20 to 40 mm (0.79 to 1.57 in). [2] They feed on colonial cnidarians such as Portuguese man o' wars, blue buttons, and purple sails.
Glaucus marginatus is a species of small, floating, blue sea slug; a pelagic (open-ocean) aeolid nudibranch; a marine opisthobranch gastropod mollusc in the family Glaucidae. [ 1 ] [ 2 ] This species is closely related to Glaucus atlanticus , and is part of a species complex (Informal clade Marginatus) along with Glaucus bennettae , Glaucus ...
Bathydevius (Greek for "deep-living deviation") is a monotypic genus of unusual, highly distinctive nudibranch native to deep waters of the North Pacific Ocean.It contains a single species, B. caudactylus ("finger tail"), and is the only known member of the monotypic family Bathydeviidae.
Generally, Chromodoris annae is a documented docile species of nudibranch. Despite the record of non-aggression, there was one reported case of intraspecific aggression between two Chromodoris annae sea slugs. Both nudibranchs were using a foot to keep them attached to the substrate below, but they were intertwined one on top of the other.
Other species include the nudibranch Glaucus (blue sea dragon), which also feeds on floating hydrozoans [18] and swallows air to stay afloat. There are multiple cryptic species of Glaucus, [19] and species in this genus may show a high degree of regional isolation. [20] [1]
