Thorunna is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae. [3] [4] [5]

Contents

Description

The genus Thorunna contains chromodorid nudibranchs with a distinctive radula, which is very small and has 17-25 teeth in a half-row. The lateral teeth are long slender shafts with bluntly bifid tips. Species in this genus rarely exceed 20 mm (0.79 in) and wriggle or vibrate their gills rhythmically. Anatomically the buccal bulb is very small relative to most chromodorids and the oral tube very long. [6]

Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size.

<i>Chromodoris</i> Genus of gastropods

Chromodoris is a genus of very colourful sea slugs or dorid nudibranchs, marine gastropod molluscs, and the type genus of the family Chromodorididae. Within the genus Chromodoris, there are currently 101 classified species. Species within Chromodoris are commonly found in tropical and subtropical waters, living as members of reef communities and preying primarily on sponges. A molecular phylogeny of the family Chromodorididae resulted in this genus being restricted to a smaller number of species than formerly, most of which have longitudinal black lines on the mantle. Many former members of Chromodoris were transferred to Goniobranchus

<i>Hypselodoris</i> Genus of gastropods

Hypselodoris is a genus of colourful sea slugs or dorid nudibranchs, marine gastropod mollusks in the family Chromodorididae. Modern usage follows a more restricted view of which species belong in this genus so there are numerous genus transfers.

<i>Ardeadoris</i> Genus of gastropods

Ardeadoris is a genus of sea slugs, specifically dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.

<i>Glossodoris</i> Genus of gastropods

Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.

<i>Cadlina</i> Genus of gastropods

Cadlina is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks historically classified in the family Chromodorididae. Recent research by R.F. Johnson in 2011 has shown that Cadlina does not belong to the family Chromodorididae. She has therefore brought back the name Cadlinidae from synonymy with Chromodorididae. The family Cadlinidae also includes the genus AldisaBergh, 1878.

<i>Durvilledoris</i> Genus of gastropods

Durvilledoris was a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae. This genus has become a synonym of Mexichromis Bertsch, 1977 Although the type species of this genus was transferred to Mexichromis two species were not reallocated nor mentioned in the text.
