Abstract
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: Berthella species eat sponges (Demospongiae); Berthellina species eat sponges (Demospongiae; ? Calcarea) and cnidarians (Scleractinia — not previously reported; ? Actiniaria); Pleurobranchus species eat ascidians; Pleurobranchaea (and apparently Pleurobranchella) species are opportunistic carnivores that accept a range of soft-bodied invertebrates (Cnidaria; Annelida; Mollusca). It appears that cnidarians (Actiniaria; Hydroida) are amongst the more preferred items in the diet of Pleurobranchaea species. The review is supplemented with observations on feeding of Berthellina citrina (Rüppell & Leuckart) and Pleurobranchaea maculata (Quoy & Gaimard) made at Leigh, New Zealand.
