The phenomenon was not mentioned in encyclopedias, textbooks, or nature magazines. The behavior of the Jamaican frog in a cave in the West Indies was still to be discovered by science. Frogs do some weird things reproductively, such as carrying their developing babies in their mouth or on their back. Some tropical frogs lay their eggs on leaves above the water, and upon hatching, the young fall into the water below as tadpoles. A group of frogs in tropical America lay single eggs in water that has collected at the base of leaves on living plants and return repeatedly to deposit unfertilized eggs as food for the developing tadpoles.
Frogs indeed have some bizarre behaviors.
The Jamaican frog was the first known instance of frogs breeding in caves or of a frog transporting fully developed young a great distance. Except the male Jamaican frogs call from a cave. Some call from the entrance, but others may call from more than 250 feet inside the cave, in total darkness. When the males call, the females find them, and after finding a mate, a female lays about 50 eggs inside the cave. She stays with them until they hatch.
