Bbc Planet Earth – Caves

The Cave of Swallows in Mexico is a 400 metre vertical shaft. Its deep enough to engulf the Empire State Building yet few people even know its existence. Lechuguilla cave, in the USA, is 193 kilometres long and 500 metres deep. It contains whole chambers filled with the most astonishing crystals including some a staggering six metres long. There's nothing like it anywhere on earth yet the name Lechuguilla is virtually unheard of. Caves are Planet Earth's final frontier and this programme will go where few have been before. Caves are one of the only habitats not directly driven by sunlight but this doesn't mean there's no wildlife. Cave angel fish are perhaps the most adapted creatures on earth since they live only on cave waterfalls – hanging on with microscopic hooks on their flattened fins. Until now they have never been filmed before.
