There's an almost surreal quality to this picture, taken by a camera trap set up to record tigers. It snapped three pictures of a golden eagle preying on a young deer in Siberia. The raptor doesn't make a habit of preying on deer, but they are known to take on larger animals.

Speaking of unusual predation sightings, has this cane toad donned a slightly askew set of Batman ears? Nope, it has a bat in its mouth. NOT a good day to be a bat. A ranger who came upon the bizarre sighting snapped this picture in Peru's Cerros de Amotape National Park. Toads have been known to eat bats, but it's not terribly common.

Here's an uneaten silver-haired bat to remind us that the whole toad-eating-a-bat thing just isn't going to happen too often.

We learned recently that bristle worms have two body clocks: a circadian clock for distinguishing night and day, and a lunar clock that helps them know when to spawn. No late-sleeping excuses for this worm.

When it's hanging out in daily life, the goosefish, also known as a monkfish, doesn't look like much. But when the homely bottom-feeder lay its eggs, the result is a striking, billowy veil that drifts in the ocean for days and looks a bit like an image from the Hubble Space Telescope.
Dinosaur tracks were recently found in Alaska, preserved in "natural casts" formed after the creatures stepped in mud and sand filled in their footprints. Here we see a hind footprint of an herbivorous dinosaur.
A new paper in the journal "Nature" asserted that the beady-eyed, prehistoric fish entelognathus primordialis ("primordial complete jaw") is the oldest known animal to have what we would consider a face. The fish, which lived more than 400 million years ago, had a face-forming jaw and cheek bones comparable to those of today's bony fishes and of most terrestrial animals, including us.

Meet Patrick, a 430-pound male gorilla who doesn't play well with others of his kind. The solution to his lack of social graces? He's going to receive six months of a kind of gorilla therapy, to try to get him to better appreciate his brethren. That's going to require an enormous couch.

A new study has revealed that cotton-top tamarins whisper. At first, the monkeys' low-amplitude vocalizing escaped detection, but amplification eventually caught the monkeys in the act. It seems likely they were muttering about a particular human supervisor whom they were not happy to see.
