Gastrotheca, also known as Marsupial Frogs, is a group of frogs found in Central and South America. Marsupial Frogs are called that way because of the dorsal brood pouch they possess. The eggs are fertilized on the female's lower back, and are inserted in her pouch with the aid of the male's toes. The eggs remain in contact with the female's vascular tissue, which provides oxygen for them.
