Description

Bates's stonebasher is an African elephantfish of the family Mormyridae from West-Central Africa, including the Ogooué drainage. The species grows to about 15 cm and has a streamlined, dark body with a blunt snout. Like other elephantfishes it generates weak electric fields with a species-specific discharge pattern; in this species the electric organ discharge (EOD) is sensitive to sex hormones, so males give a different signal, a role in mate recognition. As a bottom dweller it feeds on insect larvae and small invertebrates. Owing to limited data the species is assessed as Data Deficient (DD). It is harmless to humans.
