Tyrannodoris tigris is a species of sea slug, a polycerid nudibranch, a marine gastropod mollusc 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]
Distribution
[edit]This species is found in the Gulf of California to Bahia de Banderas.[5]
Description
[edit]Tyrannodoris tigris can grow as large as 30 cm in length. Like other nudibranchs in the genus Tyrannodoris, it is carnivorous and predatory, feeding on other sea slugs.[6]
