Adalaria proximo

Lambert, W.J., Todd, C.D., and Hardege, J.D., Partial characterization and biological activity of a metamorphic inducer of the dorid nudibranch Adalaria proximo (Gastropoda Nudibranchia), Invertebrate Biol., 116, 71, 1997. 

Other opisthobranch molluscs settle and metamorphose in response to prey items. The dorid nudibranch Adalaria proximo feeds on the cheilostome bryozoan Electra pilosa. Soluble cues secreted by live colonies of the bryozoan, but not dead, frozen, or sonicated E. pilosa, induced metamorphosis.151 Ultrafiltration showed that the active inducer is less than 1000 Da in size.43 Trypsin eliminated the inductive cue Lambert et al.48 suggested that the active inducer is a small, arginine- or lysine-containing peptide. 

Small peptides have received much recent attention as chemical inducers. Larvae of Balanus amphitrite,54 Crassostrea virginica,l Dendraster excentricus,20 and Adalaria proximo.48 all respond to waterborne peptides of more than 1000 Da molecular weight. Peptides with arginine and lysine carboxyl terminals may be very important cues for certain species of larvae such as barnacles and oysters.103...
