Common Coquí: Named after their call, the common coqui is found in Puerto Rico. This call not only serves to attract a mate, but also to mark territory. A challenging male may enter their territory and begin a duel, where they call for up to several minutes and the first to falter loses. Adults climb higher in the canopy at night and return to the ground when humidity drops in the morning, while juveniles tend to stay closer to the ground. They lay their eggs on leaves in this canopy, where they hatch directly into frogs. Males guard these eggs – although they sometimes eat a few – and chase off any predators.
Black Rain Frog: This frog is found in the forested and mountainous regions of southern South Africa, not relying on nearby sources of water. Instead, it burrows in tunnels up to 150 mm deep or lives low in the foliage of the area. Eggs are laid in similar, shallower burrows, and covered with a few layers of unfertilized eggs for protection. The male also remains near the burrow to guard it from threats, even while continuing to call.
