“As creeptastic is it may be, “The phenomenon observed is not really surprising,” said Leticia Aviles, who studies social spiders at the University of British Columbia. “Either social or colonial spiders may occur in large aggregations, as the one shown in the video.” The reason, she and others say, is simple: This is how they hunt.”
“Human beings have always been fascinated with caves. These clandestine spaces carved by mysterious forces elicit our natural curiosity, while at the same time the foreboding depth of their darkness creates a very visceral apprehension. Coupled with the baseline fear of earthquakes that many of us in California share, caves are often regarded with suspicion.
Ironically, it is the cave that typically has more to fear from encounters with humans, and for that reason White Moon Cave and the CEMEX Redwoods Property are protected, and off limits to the public. We at KQED were fortunate enough to get a rare invitation to explore this natural wonder, and capture it on video for the very first time.”
