The Sacoglossa is an order of mostly herbivorous shelled and naked sea slugs (~400 described species) that peaks in diversity in the tropical Pacific and Caribbean (Jensen, 2007; Jensen, 1996). A growing research community uses these molluscs as model organisms for studying dispersal, kleptoplasty, larval development, symbiosis, and marine speciation. Many sacoglossan sea slugs retain photosynthetically active chloroplasts from the algae they eat, incorporate extra-embryonic resources into their egg masses (Allen et al., 2009), and a few taxa can produce both pelagic planktotrophic (feeding) and lecithotrophic (intracapsularly metamorphosing ) larvae-- a rare phenomenon called poecilogony (Krug, 2009; Krug et al., 2007).
Despite the widespread interest in the biology of the Sacoglossa, many species remain undescribed and faunal lists typically underestimate their diversity (Trowbridge et al., 2009; Gosliner et al., 2008; Carlson and Hoff, 2003). The goal of this LifeDesk is to integrate sacoglossan biological information from a team of researchers thereby providing a valuable and authoritative resource to professional scientists, teachers, and amateurs.
