Trapania reticulata is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.[1]
This species was described from the Great Barrier Reef. It has also been reported from the Andaman Sea and Milne Bay, Papua New Guinea which suggests a wide distribution in the central Indo-Pacific region. It has also been photographed in Bali, Indonesia.[2]
This goniodorid nudibranch is translucent yellow with a reticulate pattern of brown pigment on the body, rhinophores, gills, oral tentacles and lateral papillae. The lateral papillae and the rhinophore clubs are unusually large in this species.[3]
Trapania reticulata feeds on Entoprocta which often grow on sponges and other living substrata.[3]
