Rattlesnakes' rich social lives
By Paul Rincon

Supposedly fearsome rattlesnakes are much more social, caring animals than their detractors would have us believe, according to new research.
A US biologist has shown that timber rattlesnakes lead rich social lives and may even form family groups. Females form birthing rookeries with other snakes when pregnant, care for their young and associate more with their sisters than unrelated snakes. Details are published in the Royal Society journal Biology Letters. Mr Clark claims the study is the first to demonstrate an ability to distinguish relatives from unrelated individuals - kin recognition - in a snake species. "They seem to have a real, strong social aspect to their lives that has been ignored," Rulon Clark, a biologist at Cornell University in Ithaca, US, told BBC News Online. "Maybe it's the body form, or the lid-less eyes, but they seem like very alien creatures. Because of that, we don't ascribe social-type feelings to them."
