Hexabranchidae is a family of colourful nudibranchs (often called "sea slugs") which contains only a single genus, Hexabranchus, with six species.
This family is one of the many families of dorid nudibranchs in the suborder Doridina, named after Doris, who was a sea nymph in ancient Greek mythology.
The genus contains one of the largest known species of nudibranch in the world, H. giganteus , which grows up to or exceeding 50 cm in length. [3] [4] Hexabranchus sanguineus is known to use chemical defenses derived from the sponge it eats and use the chemical compounds to defend itself from potential fish predators. [5]
There are six species within the genus Hexabranchus:
Aliculastrum is a genus of small sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae.
The Spanish dancer, scientific name Hexabranchus sanguineus, is a dorid nudibranch, a very large and colorful sea slug, a marine gastropod mollusk in the family Hexabranchidae.
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.
Halgerda is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Xerocrassa simulata is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.
Actinocyclus is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Actinocyclidae, and was first described by Christian Gottfried Ehrenberg in 1831.
Asteronotus is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Marionia is a genus of sea slugs, specifically dendronotid nudibranchs, marine gastropod molluscs in the family Tritoniidae.
Hypselodoris regina is a conspicuous species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Actinocyclus verrucosus is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Actinocyclidae.
Atagema ornata is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Discodorididae. It has been considered to be synonymous with Atagema intecta by some authors.
Halgerda indotessellata is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Halgerda jennyae is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Halgerda leopardalis is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Halgerda meringuecitrea is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Halgerda mozambiquensis is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Halgerda nuarrensis is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Discodorididae.
Glossodoris erythraea is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.
Phanerophthalmus is a genus of medium-sized sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae, the haminoea bubble snails, part of the clade Cephalaspidea, the headshield slugs and bubble snails.
