species. Reproductive biology Males call solitarily from margins of ponds and backwaters of streams; the call is a loud "whoorup" repeated at intervals of five to 10 seconds. An attracted female is grasped by the male by axillary amplexus and held firmly by the muscular forearms and nuptial spines on the thumbs and chest. About 1,000 eggs are deposited in a large foam nest by backward and forward motions of the male's hind limbs that mix air, water, eggs, and secretions into the nest, which usually is deposited in a depression adjacent to water. The eggs hatch in two to three days; subsequent rains flood the nest site, and the tadpoles move into the pond or slow-moving stream. Development is rapid, and metamorphosis occurs about four weeks after hatching. Tadpoles attain a maximum total length of about 3.3 in (83 mm). The body is ovoid with a rounded snout with large eyes directed dorsolaterally. The oral disc is nearly terminal and bears finely serrate jaw sheaths and two anterior and three posterior rows of labial teeth. The body and caudal musculature are brown. Toxicity The skin of the smoky jungle frog contains leptoxin, a lethal protein toxin. As of 2008, the toxin's role is unknown.
