Most ballooning journeys end after just a few meters of travel, although depending on the spider's mass and posture, [16] a spider might be taken up into a jet stream. The trajectory further depends on the convection air currents and the drag of the silk and parachute to float and travel high up into the upper atmosphere. [17]
The atmosphere is the least understood biome on Earth despite its critical role as a microbial transport medium. [2] Recent studies have shown microorganisms are ubiquitous in the atmosphere and reach concentration up to 10 6 microbial cells per cubic metre (28,000/cu ft) [3] and that they might be metabolically active.
Ballooning is a term used for the mechanical kiting [16] [17] that many spiders, especially small species such as Erigone atra, [18] as well as certain mites and some caterpillars use to disperse through the air. Some spiders have been detected in atmospheric data balloons collecting air samples at slightly less than 5 km (16,000 ft) above sea ...
Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting and ...

Ballooning spiders (parachuting). The young of some species of spiders travel through the air by using silk draglines to catch the wind, as may some smaller species of adult spider, such as the money spider family. This behavior is commonly known as "ballooning". Ballooning spiders make up part of the aeroplankton. Gliding spiders.
An invasive species native to East Asian countries including Japan, Korea, Taiwan and China, the Joro spider is believed to have first made its way to the U.S. in the early 2010s. These species ...
The stratosphere is the second-lowest layer of Earth's atmosphere. It lies above the troposphere and is separated from it by the tropopause. This layer extends from the top of the troposphere at roughly 12 km (7.5 mi; 39,000 ft) above Earth's surface to the stratopause at an altitude of about 50 to 55 km (31 to 34 mi; 164,000 to 180,000 ft).
