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]

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.
