Tyrannodoris tigris is a species of sea slug, a polycerid nudibranch, a marine gastropod mollusc in the family Polyceridae. 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".
Distribution.
This species is found in the Gulf of California to Bahia de Banderas.
Description.
"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.
