Glossodoris nigrostriata   (Eliot,  1904) (Sea Slug)
Organism information awaits expert curation
Class: Gastropoda

Size: 45 x 9 mm

Color: The dorsal surface is a pale greenish blue becoming almost white on the outer edge. On the central area there are numerous rounded orange spots and dark blue lineation; the outer area has a series of orange blobs and black blobs and bars, most of the bars running inwards from the edge. The rhinophores are closely perfoliate, the laminae being bright red in front and at the top, but mainly a dull grey blue behind and the lower half is pale blue. There is a very slightly raised pale blue sheath with occasionally a yellow spot on it. The branchiae are consistently seven in number, forming a beautiful bell cup with the tips everted; the seven plumes unite below in a pale blue base raised above the surface of the notum. The plumes are brilliantly colored, on the outside a pinkish red with orange bars or spots, down the inside reddish with some dull blue areas and in some specimens orange spots at the bases of the plumes. The large solid tail projects permanently behind the mantle, and has orange and dark blue markings on a pale blue background. The underside of the foot is translucent white, and grooved in front. The oral tentacles are pure white. The sides of the foot are pale blue with numerous orange spots and rather short blue bars.

The animal is rather slug-shaped with practically no mantle overlap, as the foot is wide in proportion; even allowing for change in shape, it remains always a narrow animal and stands high as the sides of the foot are high. The radula consists of bifid teeth with no accessory denticles. Formula: 80 x 75.0.75. The buccal armature of stout simple hooks is very regularly arranged throughout.
