Task: Question Answering
Input (English): Context: Doridoidea, commonly known as dorid nudibranchs (and previously known as the taxon Cryptobranchia), are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia., Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails"., The Euctenidiacea, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included "Onchidium" at the time of original publication., Actinocyclidae is a family of sea slugs , dorid nudibranchs , marine gastropod mollusks in the superfamily Doridoidea . This family is within the clade Euctenidiacea ., Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word "slug" is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name "snail", which applies to gastropods that have a coiled shell large enough that the animal can fully retract its soft parts into the shell)., Doridacea is a taxonomic grouping of dorid nudibranchs, shell-less marine gastropod mollusks. included in the clade Euctenidiacea of the clade Nudibranchia., Subject: actinocyclidae, Relation: parent_taxon, Options: (A) animal (B) cryptobranchia (C) doridacea (D) gastropoda (E) nudibranchia (F) onchidium
Output (English): nudibranchia
