As can be observed through these collection of photos, the spider peacock's performance involves revealing its colorful extensions. Additionally, the spider raises two legs and vibrates while shifting from side to side, in an attempt to woo its female counterpart.
An unexpected side effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiderwebs. People in the area had never seen this phenomenon before. (Courtesy: National Geographic)
