Description

The African scat is a scat (Scatophagidae) from coastal, brackish and fresh water of eastern Africa and the western Indian Ocean. The species grows to about 35 cm and has a deep, strongly compressed, almost round body with broad dark crossbars on a silver-grey ground. As an omnivore it grazes in estuaries and mangroves on algae, detritus and small invertebrates. The stout dorsal spines are venomous and can give a painful puncture wound.
