Doridoidei

Doridacean nudibranchs are characterized by having a more or less dorsoventrally flattened body, by the presence of large mantle that may have embedded spicules and may also have different projections (tubers, papillae) and the existence of a dorsal branchial plume formed by several branchial leaves surrounding the anus. Rhinophores are found in the anterior region of the notum, provided with lamellae and retractile (cryptobranch doridaceans) or just contractile (fanerobranch doridaceans).

The doridaceans are carnivorous and feed primarily on sponges and bryozoans. They feed by using their radula, that can have some to many teeth on each row, but the species of the family Dendrodorididae lack any radula at all, and feed by sucking food with their suctorial type buccal bulb. Many doridacean species have external parasites of the Copepod Crustaceans group, often of the Splanchnotrophidae family, moving primarily around the ​​gill leaves. Doridaceans have the most powerful defense mechanisms within the nudibranchs. Many species of several families present some mantle glands called MDF (for “Mantle Dermal Formations”) where they accumulate several secondary metabolites that have a large antidepredant effect when they are expelled to the outside, which happens easily when the animal is disturbed. These powerful defensive substances have allowed these nudibranchs to acquire flashy colorations  in the course of evolution, called warning (or aposematic) colorations, to prevent attacks by their possible predators.
