Spiders don't shoot their silk into the air when spinning a web. Some spiders, however, migrate by ballooning: they stand upside down, rear ends (and spinnerets) in the air, and send a thread of silk skyward, where it catches the wind or heat currents and lifts the spider toward parts unknown.

- vee-kay 11mo agoThis beautiful BBC video about Darwin's Bark Spider (a species that spits the longest silk threads and makes the largest spider webs), narrated by Sir David Attenborough is phenomenal: https://m.youtube.com/watch?v=gSwvH6YhqIM https://m.youtube.com/watch?v=gSwvH6YhqIM Spiders and Nature are incredible!
