Distribution

The type locality is the West Indies, and range is the Caribbean. All Indo-Pacific species currently termed "ornata" are a complex of cryptic species in the Elysia marginata complex (Krug et al., in press). See "cf. marginata" pages for provisional descriptions, photographic vouchers and links to DNA barcodes of species in the ornata-marginata complex.

Elysia ornata

Elysia ornata, commonly known as ornate elysia or ornate leaf slug, is a species of sea slug, a marine gastropod mollusk. This sea slug superficially resembles a nudibranch, yet it does not belong to that suborder of gastropods. Instead it is a member of the closely related clade Sacoglossa, the "sap-sucking" sea slugs.

Description[edit]

Elysia ornata can grow to about 5 centimetres (2.0 in) in length.[2] It is a translucent greenish-yellow colour speckled with white and black. 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.[3]

Distribution[edit]

Elysia ornata is a tropical species found in both the Pacific Ocean and the Caribbean Sea.[3]
