[00:00.0]Rare crickets scale the rocks
[00:02.97]while translucent earwigs
[00:05.14]and milky millipedes forage for food
[00:09.20]These are cave specialists,
[00:11.65]or troglobites,
[00:13.1]and they never leave the lava tube
[00:15.28]Over time,most have lost their eyes and colour,
[00:18.13]like this plant hopper
[00:20.23]Its tail has a curious function
[00:23.30]Any predator biting it from behind
[00:25.25]will be left with nothing but a mouthful of irritating waxy hair
[00:30.0]This is a place of ghostly stillness -
[00:33.17]a definite advantage for the small-eyed big-eyed hunting spider
[00:37.75]With its super-sensitive leg hairs,
[00:40.24]it can pick up the slightest movement in the air,
[00:43.77]and it senses the cricket's presence
[00:46.3]long before it's close enough to ambush
[00:49.0]As prey are few and far between,
[00:51.99]this may be its last meal for some time
[00:54.52]With no light and little vegetation,
[00:57.8]only the specialists survive here
[01:00.53]But that isn't the case for all lava tubes
