Tritonia plebeia (Johnston, 1828)


Tritonia plebeia

Description: This inconspicuous nudibranch is pale yellow with extensive greenish-brown mottling. Usually there are two patches of darker pigment behind the rhinophores. It has six finger-like processes on its oral veil and up to six pairs of arborescent lateral gills. Adults vary in length from approximately 16-30mm.

Habitat: Tritonia plebeia feeds on the soft coral Alcyonium digitatum and is usually found hiding at the base of the colony or amongst bryozoan undergrowth nearby. The spawn is a string laid in a convoluted coil, usually on rock at the base of Alcyonium colonies.

Distribution: This species is frequent all round the British Isles. It reaches its northern limit at Norway and its southern limit at Portugal.

Similar Species: Tritonia plebeia is similar in appearance to Tritonia manicata but not as slender as that species and much darker in colour.
