Males are homewreckers-at least when it comes to black widow spiders. Scientists have found that the male spiders actually destroy large sections of the female's web during courtship.
A strange, prehistoric worm has been discovered that once lived 500 million years ago. The worm, which was covered in spikes and had legs, actually was one of the first animals on Earth to develop armor for protection.
Could monkeys have "pet" wolves? Scientists have taken a closer look at the relationship between Ethiopian wolves and gelada monkeys and have found that even though the monkeys are prey, the wolves don't attack them.
It turns out the deep-sea sharks may be positively buoyant, a fact which surprised scientists who believed that these animals were neutrally buoyant, which would make it easier for them to swim.
Scientists have made a startling discovery. They've identified the first sensor of Earth's magnetic field in an animal: a tiny worm.
Starfish have some weird talents, and one of them is the ability to squeeze foreign objects along the length of their body and out through their arms. The newly discovered ability may shed some light on how animals are able to quickly heal themselves.
Injured jellyfish have a remarkable way to self-repair themselves. Scientists have taken a closer look at jellyfish and have found that they actually reorganize their existing anatomy in order to regain symmetry after being injured.
Scientists have discovered that hawkmoths have the unique ability to slow down their brains when hovering in order to see better in the dark and to better target the swaying flowers that they look to for food.
Some species just can't take the heat, and underground ants are one of them. Scientists have found that certain army ant species that live in tropical forests are ill-suited to high temperatures.
We may be entering the "golden age" of animal tracking. Animals wearing new tagging and tracking devices are giving scientists a real-time look at their behavior and the environmental health of the planet.
For the first time ever, scientists have witnessed polar bears preying not on seals, but on dolphins. The new findings may indicate that these species may be adapting to climate change.
