Fun facts

  • The male looks after the tadpoles and defends them with extraordinary aggression, attacking snakes, birds and even people who come near the pool, a form of parental care that is very uncommon in frogs.
  • When the pool holding its tadpoles dries up, the male digs a channel with his legs to a nearby pool so that the water flows and the young can escape: a deliberate modification of the environment that is exceptional in an amphibian.
  • It spends up to seven months buried inside a cocoon formed of several layers of shed skin that holds in moisture, and emerges as soon as the first rains soak the ground.
