Average Size: The witch prawn reaches 145 mm (5.7 inches).

Distribution: The witch prawn is widely but not densely distributed through the Indo-West Pacific region from Southeast Africa to Taiwan, including the Malay archipelago and in Polynesia. It is also found in the Tones Strait off Queensland. A marine species, it prefers depths of 33 to 46 meters (100 to 150 feet).

Comments: This small shrimp is closely related to P. Japonicus, the Kuruma prawn, and very similar to several other Penaeid species. The main difference is that the witch prawn lacks the movable spines alongside the tells on. It is usually caught with one or more of these other species and not necessarily identified separately. Consequently, information on its commercial importance is difficult to assess
