pdf 05. Observations on foam making by Leptodactylus fuscus tadpoles


Open Access


Authors: J. R. Downie

Abstract: Downie (1984) showed that recently hatched tadpoles of the ground nesting frog Leptodactylus fuscus make a foam which replaces the original nest foam made by the mating adults, but did not describe how it is made. The present results show that 1) foam-making is a communal activity: single tadpoles do not do it; 2) foam bubbles are made mainly by spitting movements oft he mouth, but also by wriggling of the tail; 3) foam is probably stabilised by mucus secreted by buccal glands; precocious secretion by these glands may be an adaptation to foam-ma king; 4) components of foam making behaviour are shown by other tadpole species out of water, but the complete behaviour is specific to recently hatched L. .fuscus.
