Frogs are frequently encountered in the damper caves, where they appear quite comfortable. However, they cannot complete their entire life cycle there, as tadpoles require sunlight to metamorphose into adult frogs.

Quite often frogs are found getting some exercise by climbing cavers’ ropes. Indeed, this method of climbing ropes with mechanical ascenders is known as the ‘frog system’.
Tadpoles have also been found (below), but will not develop fully without sunlight. They may swim out along the stream in the cave.
