Description

Pollimyrus plagiostoma is an African elephantfish (Mormyridae) from fresh water of the Congo basin in Central Africa. The species has a stocky, silvery-grey body with a small, obliquely set mouth and reaches about 17 cm. Like other mormyrids it has a weak electric organ and electroreceptors with which it orients itself in turbid water, locates prey and communicates with conspecifics. It feeds on small invertebrates and insect larvae on the bottom. Mormyrids are known for their relatively large brains and complex social behaviour based on electric signals. The species has no significant fishery value owing to its small size.
