Large species of tarantula found devouring a foot-long non-venomous snake in the wild.
Injuries caused by birds include holes in the stomach with viscera exposed, parts of body partially eaten and loss of eyes.
Minnesota Department of Natural Resources researchers are making strides toward figuring out what is killing the state's moose. Preliminary reports suggest it is a combination of health issues and increased predation.
Snowshoe hares typically shed their brown summer coats to blend in with the snowy scenery of the winter. However, when there is no snow, these mismatched animals have no place to hide and increase their chances of being spotted by a predator.
"Twilight zone" reef fish face numerous threats when diving deep underwater, but those with forked tails may have an advantage: they can swim quietly past predators and evade natural disasters such as cyclones and coral bleaching.
Most species avoid crowding but prairie voles seem to be the exception to the rule, say Duke University researchers who found that voles become less anxious and stressed when they have to share their personal space.
Using a special SharkCam, researchers have filmed the underwater predatory behaviors of great white sharks for the first time. It appears they lurk in the darkness before ambushing their prey from below. While this new study offers groundbreaking insight, researchers say there is still much to learn about these mysterious fish.
Along with visual camouflage, Puff adders have evolved a scent camouflage that makes them virtually undetectable to predators. Researchers say these African vipers are the first terrestrial vertebrates known to possess the ability to camouflage their scent.
Scientists from McGill University in Montreal, Canada, recently learned a little more about the elusive marine creatures known as narwhals by focussing on newborns.
Some insect larvae can twitch and whip inside their cocoons in order to "jump" to shadier, or more favorable, environments. Researchers say this is a unique survival technique only seen in select wasp species.
The federally endangered snail kite seeks out homes that similar to its birthplace, according to new study. But this puts the birds at an increased risk of predation.
Male crickets emit a high-frequency chirp to startle potential female mates into revealing their location. This, researchers say, likely evolved from males impersonating predatory bats.
Parasitic tapeworms use ants as intermediate hosts before ending up inhabiting their real goal: woodpeckers who feed on the ants.
Birds that take turns feeding their young prove to be more successful parents, researchers discovered in a recent study of long-tailed tits.
Camouflage is a adaptable trait used not only to hide from predators, but to sneak up on prey. Researchers recently revealed horned praying mantises have re-evolved with disruptive camouflage abilities, similar to those found in ancient lineages of the iconic insects.
