NUDIBRANCHIA
Phyllidia flava is a small to medium sized nudibranch. It is coloured yellow with several papillae on the notum. The larger papillae are white but many small ones are yellow. The colour of the animal offers camouflage to it as it feeds on yellow Axinella sponges.

Oral tentacles: 2 in number, very short, yellow.
Rhinophores: Yellow, lamellate, retractile.
Gills: Present on side of body below notum, anal opening postero-dorsal.
Foot: Yellow (ventrally) without any appendages.

Size range: 13-18mm. Uncommon.

Specific characteristics: This species is easy to distinguish from related species by its colouration, presence of white papillae over the body and its habitat.
