Tyrannodoris tigris explained

Tyrannodoris tigris is a species of sea slug, a polycerid nudibranch, a marine gastropod mollusc in the family Polyceridae.[1] 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.[2] [3]

Distribution

This species is found in the Gulf of California to Bahia de Banderas.[4]
