Miraba writes: According to a new study published in the Proceedings of the National Academy of Sciences squirrels heat their tails as part of a defense mechanism against infrared-detecting rattlesnakes. The gopher snake, a species that cannot detect infrared, does not cause the squirrels to heat their tails. The scientists created a robotic squirrel to test their hypothesis.
