Aglajidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea.[1]

Note on the authority and dates[edit]

Family names such as this one, Aglajidae Pilsbry, 1895 (1847), that have two dates (the second one in parentheses) are those names which are ruled by Article 40(2) of the ICZN Code. "If ... a family-group name was replaced before 1961 because of the synonymy of the type genus, the replacement name is to be maintained if it is in prevailing usage. A name maintained by virtue of this Article retains its own author [and date, the first date cited] but takes the priority of the replaced name [the date cited in parentheses, here alluding to Doridiinae Gray, 1847] [1]
