You're probably aware of the deplorable trade in wildlife that's driving many mammal species to extinction. Rhino horns for Chinese traditional medicine, elephant ivory for ornaments, or monkeys as exotic pets.
With sloths' relaxed and tardy nature, it seems fitting that news of the mammal's recent achievement is spreading a day after International Sloth Day.

This summer, the Bramble Cay melomys, a reddish-brown rodent that resembles a large mouse, made international news. In mid-June, The Guardian reported that the melomys, last seen in 2009, had been confirmed extinct in its only known habitat, a tiny, ...

Federal researchers believe feces from the legions of feral cats roaming Hawaii is spreading a disease that is killing Hawaiian monk seals, some of the world's most endangered marine mammals. Some conservationists advocate euthanizing those cats that ...
Chew on this: A partial skull and jaw of a small crocodile relative that lived 100 million years ago has teeth that are more like a mammal's than a crocodilian's, according to a new study. While crocodiles' toothy grins typically feature only cone ...
Usually, it's the demand for animal parts to be used in traditional Chinese medicine that spurs this trade, but now there's growing demand for live animals, especially marine mammals, for the country's exploding theme park industry. photo of orca in ...
This spike in temperature closely coincides with the dispersal of mammal groups to new parts of the world, and their diversification into three groups that are still with us today.
Two mammal-like reptiles were confirmed to be the species that led to the rise of the mammals. These two ancient reptiles belong to the group of ... "These new fossils help [us] understand in more detail the evolution of pre-mammalian forms that gave ...
The study was originally inspired by the operating principle of the electronic noses and tongues systems which mimic mammalian smell and taste recognition, combining semi-specific sensors and chemometric techniques for monitoring biochemical ...
For the consciousness-raising exercise this year, the RSB has, perhaps wisely, decided to go for maximum cuteness, asking the public to vote for their favourite non-domestic mammal. All 101 species of Britain's wild mammals are eligible, including such ...

Cynodonts first appear in the fossil record around 260 million years ago, but the earlier specimens were definitively reptiles with mammalian features rather than mammal/reptile crosses. These new foot long creatures are thought to have eaten insects ...
A small rodent that lived only on a single island off Australia is likely the world's first mammal to be a casualty of climate change, scientists report this week.
In this list (summarized by an infographic in sciences et Avenir, which spotted the information), the mongoose commits more intraspecies violence than any other mammal species, causing nearly 20 percent of their deaths (mostly due to infanticide ...
When it comes to wildlife trade and trafficking, sadly, way too many roads lead to China. Usually, it's the demand for animal parts to be used in traditional ...
A comet impact 55 million years ago may have helped mammals dominate the Earth. It could have triggered a rapid phase of global warming linked to the expansion of mammal groups during the Eocene time period. Writing in the journal science, a team of ...
Unlike its larger crocodile cousins with simple conical teeth, Lavocatchampsa sigogneaurussellae owns complex teeth with cusps and basins, just like smaller mammals. The specialized teeth of the tiny crocodile suggest that their diet consists primarily ...

That yawn by your horse may be revealing more than a touch of boredom or tiredness. Researchers now tell us that the length of yawn in mammals tells us something about the number of cortical neurons in their brain and the weight of the crucial organ.
Dr. de Lapparent de Broin says "In the early 1990s, Cretaceous mammals were intensively searched for in Africa; until full preparation eventually revealed single-rooted teeth, it was hard to conceive that the specimen could belong to a crocodile ...
Researchers at the University of Leicester, UK, have developed a new photonics-based approach for analyzing toxic chemicals in complex samples that mimics the way mammals smell and taste. The scientists say that the technique ... The study was inspired ...

Britons have been asked to name their favourite mammal. A Royal Society of biology (RSB) poll, launched on Sunday, will seek to pinpoint which non-domestic creature - found within our shores and coastal waters - is closest to the nation's heart ...
Could your next wetsuit be fashioned after the fur of hairy, semi-aquatic mammals like beavers and sea otters? Quite possibly yes, if Massachusetts Institute of Technology researchers have anything to say about it.

It may come as a surprise, then, that it's the world's most poached and trafficked mammal - even more than elephants and rhinos, two more high-profile victims of the Illegal Wildlife Trade.
Carnivoran and ungulate communities, like mammals overall, are more closely linked with past climate. Their startling finding, that past climates are more important to the structure of mammal communities than modern climate, implies that African mammal ...
KAMPALA, Uganda Because of its distinctive coat of hard shells, the pangolin, or scaly anteater, has been called the world's most heavily trafficked mammal. More than one million have been poached in the past decade, threatening the creature with ...
An artistic interpretation of what the newly identified cynodont Bonacynodon schultzi looked like during its lifetime about 235 million years ago during the Triassic ...
October 4 (SeeNews) - UK environmental consultancy APEM on Monday said it has been hired to carry out aerial bird and marine mammal surveys of ScottishPower Renewables' East Anglia ONE North offshore wind area in the UK. APEM is also continuing ...
But the study also argues that while we may not take number one in killing our fellows, that's not to say we wouldn't take number one as the most lethal mammal on this planet. However, Polly Wiessner, an anthropologist at the University of Utah, and ...
Regulators have detailed new rules that will require countries exporting wild-caught seafood to the US to measure and reduce bycatch of marine mammals by 2022. Countries that don't comply could see their exports banned from US entry, Nina Young, ...
You'd be forgiven for thinking humans are the sh*ttiest mammals of all, judging by the behaviour of the ones you see making the headlines.
The country's Karoo region is home to a wealth of therapsid fossils, making it an important place to study the ancestry of mammals. Brink was not the first palaeontologist to use serial grinding. The technique emerged at the beginning of the 20th century.
Meerkats are the most murderous mammals on Earth, according to a recent study on violent behavior published in the journal Nature.
The second most violent mammal is the red-tailed monkey, followed by the blue monkey and various lemurs (Ed Yong of The Atlantic created a nifty chart of mammals most likely to kill their own kind). When it comes to humans, we're still pretty violent ...
