A cold-blooded lizard that likes the cold?

This striking new lizard from Peru prefers an unusual habitat - cold mountain streams.  The article doesn't say how much time the animal spends in the water vs. sunning itself (which it must do), but it's one more reminder that life is endlessly adaptable.  When we have, for example, crabs that live almost entirely on land and get as big as trashcan lids (dustbin lids for you British readers), fish that prefer to be on land (a tiny Brazilian catfish will instantly get out of the water if placed in it), and animals that flourish in superheated, poisoned water around hydrothermal vents, we should always keep in mind that "Life finds a way" isn't just a line from a movie.
