Vocal Sac-Brooding Frogs: Rhinodermatidae

According to the World Conservation Union (IUCN), Chile Darwin's frog is Critically Endangered, which means that it faces an extremely high risk of extinction in the wild; and Darwin's frog is Vulnerable, which means that it faces a high risk of extinction in the wild.

The Chile Darwin's frog is especially at risk. Since 1994, at least 80 percent of all members of this species have disappeared, and some scientists fear that it may already be extinct. People had seen Chile Darwin's frogs in their habitat until 1978, but trips to find the frog since then have found nothing. Scientists are not sure why this frog has vanished, but think that habitat loss, and particularly the removal of the plants where they live, may be part of the reason.
