Full Description

"After as little as 12 h of being introduced into aquaria from the wild, type I males will inhabit the shelter, defend it as a nest, and broadcast acoustic signals (Bhums[) to attract females (Brantley and Bass, 1994; Lee and Bass, 2004)."

"Type I males held in identical aquaria will readily acoustically court even in the absence of females; this call likely serves in part as a Bbeacon[ to draw females to the spawning grounds (Brantley and Bass, 1994; Lee and Bass, 2004)."
