Abstract

Weakly electric fish can generate an electric field with their electric organ (EO). Through 14,000 electroreceptors distributed on their skin, they can sense the electric field perturbation induced by a nearby prey or object. Many researchers have studied to reveal the mechanism of electrolocalization. Simulations are typically based on an analytical model which represents the EO as a set of charge, or a model based on finite-element method (FEM) in a 2-dimensional space. In this paper, we show a 3-dimensional FEM model to test the electric perturbation of various shapes of objects. Using this model, we show that a measure of caudal relative slope or tail-side half width at half maximum can estimate the lateral distance of a target object regardless of its size, shape and rostrocaudal position.
