Specimens of Beionesox belizanus Kner from throughout Central America were examined to determine the extent of geographic variation for eight morphometric and five merlstlc characters. These characters were used to consider the validity of the subspecific name Beionesox belizanus maxillosus Hubbs. Specimens collected in Belize, Central America, were examined for life history traits, including feeding, reproduction, age and growth. Experiments were conducted using several species of Gambusla as prey items to determine whether Beionesox belizanus selectively preys on different sizes or species of Gambusla. The
