Placida dendritica
Placida dendritica is a species of small sea slug, a marine opisthobranch gastropod mollusk or micromollusk in the family Limapontiidae.
Despite a superficial resemblance, this is not a nudibranch, it is a sacoglossan.
Like most sacoglossans, Placida dendritica feeds on coenocytic green algae. It is able to retain the chloroplasts for a short period.
