Nembrotha kubaryana

Nembrotha kubaryana, also known as the variable neon slug, is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Polyceridae. Its synonyms include Nembrotha nigerrima.[1][2]

Contents

Distribution

This species occurs in the tropical Indo-West Pacific.[3]

Description

This animal can reach a total length of more than 120 mm. It is a large dark-bodied nudibranch which may have green stripes running down the length of the body or have green raised spots. The margin of the foot and head is a vivid red-orange. The rhinophores and gills may be red or green. Nembrotha kubaryana is easily confused with a similar species, Nembrotha cristata although the latter has no red orange border on its foot.

Ecology

The variable neon slug feeds on ascidians and has been observed feeding on the green-ringed ascidian, Sigillina signifera.[3]

Chemical defences

Nembrotha kubaryana uses the toxins in its prey ascidians to defend itself against predators.[4] It stores the ascidian's toxins in its tissues and then releases them in a slimy defensive mucus when alarmed.[citation needed]
