Embletonia gracilis

Embletonia gracilis is a species of sea slug, a dorid nudibranch shell-less mollusk in the family Embletoniidae.

Description
Embletonia gracilis is translucent white, and has been described to be less than 8mm, but can grow to be 20-30mm in length. They have an elongated shape and a single row of cerata, which divide into four parts at the tip, containing nematocysts. They do not have oral tentacles and instead, flat oral lobes next to the mouth. Several studies suggest that they eat hydroids.

Distribution
