Did You Know?

• Females construct a sponge-like foam nest, roughly 10 to 15 cm across, on tree branches overhanging ponds and marshes, laying 300 to 800 pale yellow-white eggs inside it. Source
• Inside a single foam nest, sperm from multiple males compete intensely to fertilize the eggs, a phenomenon thought to explain why males have unusually large testes for their body size. Source
• Once hatched, tadpoles wriggle their way out of the foam nest and drop directly into the pond or marsh below to begin their aquatic life. Source
