Members of the genus Thuridilla are brightly colored but not cryptic and are often found crawling on substrates other than the algae they eat (Gosliner, 1995).
"The living animals (Fig. 1D) are light blue. The edge of the parapodia is lined with a band of bright orange. Immediately inside this band is a narrower black band. Two black lines and an orange band are present at the base of the parapodia, as well. There is a narrow black band surrounding the head, near the level of the eyes. A v-shaped black band is near the middle of each rhinophore and the rhinophores are tipped with orange. Orange pigment is present on the anterior margin of the foot.
There are paired lateral and posterior [dorsal] vessels. These vessels are thin compared to most other species. The anterior vessels are bifurcate near their tips. The more posterior vessels have separate origins from the pericardium and give rise to one or two short branches. (Gosliner, 1995, Proceedings of the California Academy of Sciences, 49(1), p. 9)."
Only known from Indonesia (Gosliner, 1995).

Distribution and habitat
This species can be up to 3 cm in size. The body is partially covered by the fold of the lateral parapodia. The mantle is bright blue, and the edges of the parapodia are framed by two lines: a fine black one and an orange one on the external side.
The smooth rhinophores and the oral cavity are also marked with a black line and with an orange band.
