The Surinam horned frog (Ceratophrys cornuta), also known as Amazonian horned frog, is a bulky frog measuring up to 20 centimetres (7.9 in) found in the northern part of South America. It has an exceptionally wide mouth, and has horn-like projections above its eyes. Females lay up to 1,000 eggs at a time, and wrap them around aquatic plants. The frog eats other frogs, fish, lizards, and mice. Tadpoles of the Surinam horned frog attack each other (and tadpoles from other species) soon after being hatched. This species was once considered the same species as Ceratophrys ornata. Wikipedia →
