Favorinus blianus is a species of sea slug, an aeolid nudibranch in the family Facelinidae.
The maximum recorded length is 30 mm. [1]
This species was described from Pembrokeshire, Wales [1] where it is a scarce animal. It has also been reported from Norway, England, Denmark, and Galicia, NW Spain. [2]
Nudibranchs are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown," "marigold," "splendid," "dancer," "dragon," or "sea rabbit." Currently, about 3,000 valid species of nudibranchs are known.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are actually gastropods, i.e. they are sea snails that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells.
Opisthobranchs is now an informal name for a large and diverse group of specialized complex gastropods which used to be united in the subclass Opisthobranchia. That taxon is no longer considered to represent a monophyletic grouping.

Numerous biologists (malacologists) and citizen scientists, including many scuba divers, study the marine mollusks known as opisthobranchs, which are a large and diverse group of shelled and (mostly) shell-less, saltwater gastropods, the common name for which is sea slugs and bubble snails. Symposia and workshops on opisthobranchs are meetings where those who specialize in studying these animals meet in order to share ideas, information, and knowledge.
