Description
Dorsal view of Palisa papillata.

The body is elongate.[3] Rhinophores are tuberculate.[3] Oral tentacles are long.[3] Cerata are arranged in clusters forming a single row along each side of the dorsum.[3] Background color is translucent gray with numerous opaque white spots on both the dorsum and cerata.[3] Cerata are with a pale blue digestive gland and characteristic black or dark brown spots at the base.[3] The maximum recorded body length is 15[3] or 16 mm.[5]

Habitat

Minimum recorded depth is 0.1 m.[5] Maximum recorded depth is 1 m.[5]

It was found among algae in Panama.[3] It is probably feeding on epiphytic hydroids.[3]
