This species was described from the Caribbean Sea.[3] It was later redescribed from new material from Martinique, the Bahamas and Florida.[4] It has also been reported from the Canary Islands and Cape Verde Islands in the eastern Atlantic.[5]

Description

Flabellina dushia is a flabellinid with opaque white pigment covering most of the body. The translucent body is visible through areas at the bases of the tentacles and rhinophores, behind the eyes and bases of the cerata. The rhinophores and oral tentacles are translucent at the base and covered with opaque white pigment in the outer two thirds. Mature animals reach 15 mm in length[4] or up to 20 mm.[6]

Ecology

The minimum recorded depth for this species is 1 m; the maximum recorded depth is 20 m.[6]
