Hypselodoris jacksoni has a relatively high body profile, an elongate body, and a narrow mantle skirt. The gill pocket forms a high raised collar as in H. krakatoa.

The background colour of the mantle and the foot is translucent greyish often covered in part by opaque white. There is an open reticulation of relatively thin dark brown to black lines arranged in a symmetrical pattern down the mantle. There is usually an irregularly shaped and slightly raised milky yellow patch in each of the spaced formed by the reticulation. A similar colour pattern is found on the sides of the body/ foot. There is a thin orange band around the mantle edge but this absent on the edge of the foot except at the posterior end.

The gills are held erect. They are triangular in cross section, translucent, with an orange line up each edge. The rhinophores are an intense orange with a pale whitish tip.
