[4] Pleurobranchaea bubala has an oval sandy-coloured body with large opaque white bumps on the notum.

It can be confused with Pleurobranchaea tarda, which is smaller, has smoother skin, and can be found in deeper water.

[2] he dorsal surface has a honeycomb-like, mottled coloration of brown, black, and yellow.

When submerged, two dorso-laterally positioned rhinophores (chemosensory tentacles) often extend, along with a tube-like mouth.

From the ventral view, feather-like gills (branchia) are clearly visible on the right side, along with the foot.
