Berghia stephanieae is a small nudibranch of the aeolid family, known to feed voraciously on the anemone Aiptasia pallida, a common pest in tropical aquaria. Berghia is sold in the aquarium trade for anemone density control. Though well documented in the aquarium context, studies on Berghia-Aipatsia interactions in the natural environment are more scarce. Being a specialised predator (as are most nudibranchs) that feeds exclusively on A. pallida, it is unclear how both species can coexist in the natural environment without B. stephanieae causing local extirpation of its prey. Building on the discovery of kleptopredation in 2017 in the aeolid nudibranch Cratena peregrina, the current research investigates the possibility of this mechanism being used by other nudibranch species, here B. stephanieae. C. peregrina is a highly specialised predator known to feed exclusively on hydroid E. racemosum polyp, yet half of their diet was found to consist of planktonic prey acquired through kleptopredation. The current research investigates the feeding strategy of B. stephanieae, and the possibility of kleptopredation. B. stephanieae were reared and fed in the laboratory with either kleptopredation treatment (recently-fed anemones) or control diet treatment (unfed anemones). Their physiology was studied over time under each treatment conditions, to assess the possible benefits of kleptopredation on the energy budget. Preliminary results suggest kleptopredation is exhibited by Berghia stephanieae. Growth, spawning, and respiration measurements show that this feeding strategy could provide energetic benefit to the nudibranch predator by allowing more energy to be invested in growth and reproduction.
