Tyrannodoris tigris is a species of sea slug, a polycerid nudibranch, a marine gastropod mollusk in the family Polyceridae.[2] It is a known predator of Tambje eliora and Tambje abdere, two species of smaller nudibranchs. The chemical extracts of all three species contain tambjamines, which were traced to Sessibugula translucens, a food source of these species. It is hypothesized that tambjamines are a chemical defence mechanism against feeding by the spotted kelpfish Gibbonsia elegans.[3][4]
