Ecology Summary - Apteronotus albifrons
Ecology of Apteronotus albifrons
 
Main Ref. Lannoo, M.J. and S.J. Lannoo, 1993
Remarks The fish swims backwards (reverse swimming) which is characteristic of two foraging behaviors: searching for prey and assessing it. In assessing a potential prey item, it typically scan the prey from tail to head by swimming backwards, then ingest it after a short forward lunge. A scan in the opposite direction - from head to tail by forward swimming - would have the prey located near the tail and out of position for the final lunge (Ref. 40007).
