that suborder of gastropods. Instead it is a member of the closely
related clade Sacoglossa, the 'sap-sucking' sea slugs.
To be confused with
- Painted Elysia Thuridilla picta.
Size: 1 to 2.5 cm, max 5 cm.
Colour: It is a translucent greenish-yellow colour speckled with white and black.
Shape: It has broad parapodia each edged with an orange band and a black margin. The rhinophores are similarly coloured with a band of orange and dark tips.

photosynthesis for several months at a time.
