Ardeadoris angustolutea

Ardeadoris angustolutea is a species of colourful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Chromodorididae.[2] It was transferred to the genus Ardeadoris on the basis of DNA evidence.[3]

Distribution

This species was described from Ruby Reef, 15.733°S 145.783°E / -15.733; 145.783 Great Barrier Reef, Queensland, Australia. It occurs in the tropical Indo-West Pacific regions, with confirmed sightings from the Philippines, Thailand, Guam, Hawaii and the Marshall Islands.[4]

Description

The mantle in this species is an almost translucent white in colour. The mantle border ranges in colour from opaque white to orange-yellow. The midline of the body has a more opaque line that runs from the rhinophores to the posterior branchia (gills). The rhinophores and branchia have an orange-brown tint.[5][6][7]

Ecology

The exact food source for this sea slug is not yet known but the type specimen was found on a purple sponge species which is probably its food.[4]
