The Aba (Gymnarchus niloticus) is a freshwater fish of the family Gymnarchidae that grows up to 167 cm.
Description
The aba aba is a large, remarkable African freshwater fish, the only species of the family Gymnarchidae, related to the elephantfishes. The species can reach about 1.7 metres and has an elongate, rearward-tapering body without pelvic, anal and caudal fins; propulsion comes from a single long, continuous dorsal fin with which it swims backward as easily as forward. It generates a continuous weak electric field to navigate turbid water and find prey. As an obligate air-breather it gulps air at the surface. During high water it builds a flask-shaped nest in the vegetation. It is an aggressive predator with sharp teeth; keep clear of the mouth.
