The hippos, descendants of four imported from Africa illegally by the late drug lord in the 1980s, have spread far beyond the Hacienda Napoles ranch and are a biodiversity problem. 

Urgent action needed as DNA tests show their genetic diversity is so low they could vanish from the country in 30 years

Health concerns are growing in East Palestine as reports rise of animals getting sick and some even dying. The train derailment is causing struggles not just for the animals, but their owners as we…

If you think you have trouble telling when someone's into you, just be grateful you're not a giraffe.

Dogs lead lives of loneliness. Grey parrots die years earlier than their natural lifespans. And it is hard to fathom the boredom of pet fish

A bald eagle has laid two eggs this month in a Southern California nest and nature lovers will watch for the hatchings via an online live feed.

You might be wondering: why was anyone looking for a snake clitoris in the first place? The short answer is that, well, men aren't great at finding clitorises in general, so of course the male-dominated science fields wouldn't even know where to start looking for one on a snake.

A group of researchers at the University of British Columbia got to work locating, measuring and then evaluating a number of these overpasses to see how different dimensions impact how effective an overpass is at encouraging wildlife to cross.

The biggest single-building pig farm in the world speaks to the dystopian nightmare that is animal agriculture.

Scott Kemp first saw glow-in-the-dark millipedes in the Illawarra 18 years ago, but he had no idea he was making a significant scientific discovery.

Israeli researchers say they have developed gene-edited hens that lay eggs from which only female chicks hatch. The breakthrough could prevent the slaughter of billions of male chickens each year, which are culled because they don't lay eggs. The female chicks, and the eggs they lay when they mature, have no trace of the original genetic alteration

More than 140 million birds have died and hundreds of millions of pounds have been spent in the past year in the US, UK and EU in tackling bird flu, as some experts said continual culling was “morally” wrong.
