Thordisa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae. [3] [4]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Sea slug group of marine invertebrates with varying levels of resemblance to terrestrial slugs

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.

Nudibranch order of molluscs

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", and "dragon". Currently, about 3,000 valid species of nudibranchs are known.

Species

Species in the genus Thordisa include: [3] [5] [6]

Thordisa aculeata is a species of sea slug, a dorid nudibranch, shell-less marine opisthobranch gastropod molluscs in the family Discodorididae.

Thordisa albomacula is a species of sea slug, a dorid nudibranch, shell-less marine opisthobranch gastropod molluscs in the family Discodorididae.

Species brought into synonymy
<i>Sebadoris nubilosa</i> species of mollusc

Sebadoris nubilosa is a species of sea slug, a dorid nudibranch, shell-less marine gastropod mollusks in the family Discodorididae.

<i>Jorunna parva</i> species of mollusc

Jorunna parva is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Discodorididae. The species was first described by Kikutaro Baba. The resemblance of Jorunna parva's rhinophores to bunny ears and its other features facilitated a surge in popularity on Twitter throughout Japan in 2015. The rhinophores are classified as sensory organs for the act of chemoreception. Sea slugs eat sponges, which contain toxins. Those toxins are used for cancer treatments. Sea bunnies are considered to be one of 16 species in the family Discodorididae. The fur is called caryophyllidae, which is composed of fleshy protuberances called papillae, as well as spicules, which are used for sensory functions.

Thordisa verrucosa is a species of sea slug, a dorid nudibranch, shell-less marine opisthobranch gastropod molluscs in the family Discodorididae.

Platydoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae. These nudibranchs are large and often brightly coloured, but normally live concealed beneath rocks or loose coral, feeding on sponges. During the night they become more active, searching for new food sources or mates. Many species were described in the 19th century and a revision in 2002 added six new species.
