The male "Gastrotheca cornuta" calls from high in the canopy to attract a mate. His call sounds like a champagne cork being drawn. The eggs of "Gastrotheca cornuta" are the largest known amphibian eggs. They are carried in individual chambers in the female's brood pouch. The developing embryos have umbrella-like external gills that spread out against the pouch wall, which is highly vascular. Gas exchange takes place through the wall of the pouch. There is no free-living tadpole stage for this species and when their development is complete, tiny froglets make their way out of the brood pouch.
