Hexabranchidae is a monotypic family of colorful nudibranchs (often called "sea slugs") which contains only a single genus Hexabranchus, with two species, and has no subfamilies.
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. sanguineus, which grows up to or exceeding 40 cm in length.[4]
