Abstract
Laboratory and field tests were conducted to show the roles of pelagic prey availability and nocturnal darkness in inducing floating and air-breathing behaviors in Ambystoma tigrinum larvae. Both pelagic prey availability and nocturnal darkness independently increase the frequencies of floating and air breathing. Air breathing and floating are correlated. Lungs are necessary for larvae to remain suspended and feed in the water column. Results suggest larvae float in response to darkness to feed on pelagic prey.
