This galaxy of little lights is created by thousands of living creatures. Any animal that lives in a cave has to cope with complete blackness, but in New Zealand some have turned this darkness to their advantage. A silken strand is lowered from the ceiling, alongside hundreds of others. Beautiful though these threads are, they have a sinister purpose. This is a cave glow worm. To trap its prey it goes fishing with a line of silk. The silk comes from glands in the glow worm' s mouth and is loaded with droplets of mucus. Each glow worm produces dozens of these threads. Once its lines are set, the glow worm hangs from a mucus hammock and waits, like a patient angler. But the glow worm doesn' t leave everything to chance. |
