Description

Notodoris gardineri can reach more than 10 cm long. In different geographical regions the background color of the animal can vary. In the archipelagoes of the Maldives and Laccadives, the body is black with yellow spots while in the rest of the distribution range the body is yellow with black spots. The size and numbers of spots vary from one individual to another. The gills are situated in the center of the dorsal side, they are yellow and protected by three round lobes. The body is stiff and protected by small spicules. The rhinophores are smooth, simple, yellow and retractable. Notodoris gardineri can be mistaken for Notodoris minor, whose body colour is also yellow with black markings except that in the latter the black forms lines on the body and not spots.

Distribution

This species occurs in the tropical Indo-West Pacific.

Habitat

This nudibranch lives on the external slope or top of coral reefs, commonly at 7 to 15 m depth.[3]

Feeding

Notodoris gardineri feeds mainly, according to the actual observations, on sponges of the family of Leucettidae as Pericharax heterographis or Leucetta primigenia.

Behaviour

This Notodoris is benthic and diurnal, moves at sight without fear of being taken for a prey.
