Description

The genus Acanthozoon is physically characterized by a dorsal side with small raised papillae and ruffled edges. Their body is elongate oval. The species of this genus have a complex and very folded pharynx. They also have small pseudo-tentacles that prick up like ears. Because of their papillaed upper surface, they are easily confused with species from the genus Thysanozoon, which are also endowed with dorsal papillae. However Acanthozoon possess only a single male copulative organ contrary to Thysanozoon.[2]

Biology

This genus live in warm tropical marine waters. They are benthic and carnivorous.
