This species is found in the Indo-West Pacific oceans, off Western Australia, and the Mediterranean, and Red seas.

Syphonota differs from the other Aplysiidae genera, through the position of the rhinophores (head tentacles), which are further back, almost between the parapodial lobes.

The parapodia, fleshy winglike outgrowths, come to a noticeable high point at the top of the animal.

The body coloration is whitish to green, with brown specks and a complicated network of white lines (hence the name 'geographica').

[1] This sea hare lives in lagoons and bays on sandy substrates.
