Tyrannodoris tigris (Farmer, 1978)
Tyrannodoris tigris is a voracious predator of other nudibranchs, being especially fond of Tambja eliora and Tambja abdere. Roboastra tigris is believed to track the slime trails of both Tambja eliora and Tambja abdere through chemoreception utilizing the cephalic tentacles.
Its predominant body color is a greenish, yellow-ochre, with five longitudinal dark navy blue stripes outlined by light green. The rhinophores and oral processes are blue-black. The gills are blue-black distally, with light green bases.
