Planet Earth

Series 1 Episode 4: Caves

This edition is all about Earth's final frontier - caves. Deer Cave in Borneo is a daytime retreat for five million bats, and their droppings support an entire community of creatures. Troglodytes like the Texas cave salamander and Thailand's cave angel have neither eyes nor pigment, and the entire populations of both are found in just a couple of caves.
