A review of diets in the Notaspidea (Mollusca: Opisthobranchia)

open access: yesJournal of the Malacological Society of Australia, 1984
This paper reviews the scattered and often anecdotal literature on foods for the opisthobranch order Notaspidea. All Umbraculacea are sponge-feeders (accepting sponges of the class Demospongiae only). The Pleurabranchacea shows a diversity of diet: Berihella species eat sponges (Demospongiae); Berthellina species eat sponges (Demospongiae;?

Chemical defenses in Sacoglossan Opisthobranchs: Taxonomic trends and evolutionary implications

open access: yesScientia Marina, 2004
Sacoglossan sea slugs (Mollusca: Opisthobranchia) are one of the few groups of specialist herbivores in the marine environment. Sacoglossans feed suctorially on the cell sap of macroalgae, from which they "steal" chloroplasts (kleptoplasty) and deterrent
