Review

Caves: the final frontier. And, for obvious reasons, the least explored places in the world. In this episode David Attenborough visits the deepest cave shaft in the world (Mexico’s Cave of Swallows) and wanders around Borneo’s Deer Cave, home to three million (yes, three million!) wrinkle-lipped free-tailed bats, which have made a veritable mountain of guano that pulsates with millions of wiggling cockroaches.

The poor crew spent a month filming the wildlife that lives around this poo, which must have been a horrendous (and smelly) ordeal – not that you’d know it listening to Attenborough’s soothing narration. As always, it’s awe-inspiring stuff.

Summary

David Attenborough looks at the world's caves, including the Lechuguilla Cave in America, which contains chambers filled with 6m-long crystals. He observes creatures in Texas and Thailand that never see daylight, and inside Deer Cave in Borneo he finds five million bats whose droppings support an entire ecosystem.
