Thuridilla indopacifica Gosliner, 1995

Thuridilla indopacifica is a brightly coloured Sacoglossan species, easy to identify with its undulating orange parapodial border, thin black sub-marginal line and longitudinal row of cobalt blue or turquoise patches. The flanks of the animal are usually pale green with tiny white specks.

Published sightings indicate a range extending across the Indian Ocean, from the Gulf of Oman, East and Southern Africa to Western Australia and Bali in Indonesia. The individuals shown here were found out in the open crawling on algae-covered rocks or sand in the Andaman Sea. This species is probably the least common of the three Thuridilla species presently known from the Andaman Sea, the other two being Thuridilla gracilis and Thuridilla moebii(both links courtesy of Bill Rudman's Sea Slug Forum). The specimen shown above was 20 mm long.
