Guana Cay, 0.5 m, Abaco, Bahamas, western Atlantic, August 8, 1998, On Sargassum attached to the substrate. Length: 8 mm. Photographer: Colin Redfern.
This is a small elongate aeolid, growing to approximately 12 mm in length, with the foot extended into a relatively long tapering 'tail'. The cerata are arranged into approximately 5 clusters down each side, one precardiac and the others behind the heart. The tapering rhinophres are annulate with up to 10 rings. The body is a translucent greyish white with very distinct opaque white markings. The head and oral tentacles are opaque white, and from the head a broad opaque white median band runs back between the rhinophores to the tip of the tail. The band is narrowest when it is passing between each pair of ceratal clusters and broadens in the gaps between each pair of ceratal clusters. A similar broad white band runs down each side of the body just below the cerata. The bright red or orange digestive gland duct is clearly visible through the translucent clear ceratal wall. At the upper tip of each digestive gland there is a narrow darker band of the orange or red. The cnidosac at the tip of each ceras is translucent white, giving each ceras a whitish tip.
