Researchers investigating the agility of arboreal snakes at cold temperatures have started to detail how and when reptiles tumble out of their trees. Snakes, like all cold-blooded animals, cannot control their body temperature. Instead, they tend to go along with the conditions of their environment, slowing down their movement as the temperature drops. In particularly cold conditions, some reptiles become completely immobile, which can cause problems. A cold snap in Florida this past winter, for example, caused iguanas to fall out of their arboreal homes.

Your mother may have warned that you'd get a tummy ache if you scarfed down your food, but for one Australian snake, eating too fast could be deadly. The death adder dines on frogs, but some of them are poisonous. So the snake has learned patience: After striking a particular poisonous frog, it waits for its victim's toxin to degrade before it dines. The finding could help ecologists decipher how one species can outevolve another.
