A native lizard species from Florida has demonstrated some rapid evolution - in as little as 15 years - due to pressures from an invading lizard species hailing from Cuba, according to a recent study.
A pair of prairie butterflies from Minnesota have just gained protection under the Endangered Species Act, the US Fish and Wildlife Service (FWS) announced Thursday.
Are you willing to chow down on some poison just to get the girl? No? Then you're probably not a great bustard, a particularly large Eurasian bird that purposely eats poisonous beetles to prove to prospective mates how tough and healthy it is.
Controversy has long surrounded the disappearance of the monstrous Megalodon, the ocean's largest shark ever, but a new study concludes that this 60-foot-long predator became extinct 2.6 million years ago.
In a stunning turn of events, it has been scientifically confirmed that the offspring of a virgin captive snake named Thelma are hers and hers alone, boasting no genetic information from a male parent. This is a remarkably rare example of a "virgin birth," a natural phenomenon that still leaves experts scratching their heads.
Apparently reptiles have an ultimatum in life. Live hard and die young, or live long and healthy lives by abstaining from sex and meat.
Indian veterinarians and livestock farmers seem to be complying with the ban of a drug that has nearly eliminated local vulture populations. Now experts are saying that these vultures are no longer on the decline, giving conservationists hope for a steady recovery.
Apparently when salamanders party, everyone's invited. At least, that was the case for a recent shindig in Missouri where a hoard of salamanders piled up on a homeowner's doorstep for a surprise visit.
Wild chimps are using the cover of darkness to disguise their nighttime antics, which consists of raiding nearby farmland for crops, according to new research.
Nevada's ongoing drought continues to make food scarce in the mountains, forcing hungry black bears to openly forage in the middle of town, sometimes in the most unusual places, reports say.
Imagine spending another lovely day on the beach when, out of the blue, great forests of foreign seaweed wash ashore. The last thing you'd likely do is say, "hm, I think I'm going to live in this stuff!" Strangely, that's exactly what crabs and other crustaceans are doing, and it's working out really well for them.
Researchers have long known that fish can used their fins for more than just locomotion. Display is a common use for elaborate fins and coloring, used to attract mates or even ward off or hide from predators. Now a new study of male bluefin killifish shows that their display fins are also used to communicate specific things.
You may be familiar with the idea that the young are the legacy and backbone of any community, leaving the old to grow fat and retire without a care in the world. It would be nice to think that this romantic concept applies to animal populations too. However, researchers are arguing that this is just not the case. Fisheries are extremely dependent on their old, slow, but still fertile females to keep populations up.
A new series of DNA analyses have revealed the possible beginnings of an invasion of Lake Michigan, with evidence of Asian carp showing up in a pair of Michigan tributaries.
A longstanding question among scientists is whether evolution is predictable, and they may have finally found their answer in two distinct species of squid. The genetic underpinning of bioluminescence, or the ability to emit light, in these cephalopods may in fact be surprisingly predictable, new research shows.
