Echis, also known as the saw-scaled viper, dominates snakebite statistics and kills more people annually than any other.
Indian-made antivenoms, common throughout Africa because they are affordable, showed little-to-no neutralisation of the African Echis venoms.
Venom from lizards such as the Komodo dragon has the potential to treat heart attacks, strokes and blood clots.
A group of lizards in Brazil have evolved bigger heads in just 15 years thanks to their new environment.
The beautiful Chinese cave gecko, or Goniurosaurus luii, is highly prized by poachers.
Biologists have a centuries-old tradition of publishing on rare and endangered species. But poachers are using open-access information to target valuable and fragile new species.

Mammals' ancestors had a third eye and the fossil record of its disappearance tells us the story of the evolution of one of our most important features: warm blood.
An anaconda peers above and below the water. Did snakes evolve on land or underwater?

One of the enduring controversies in evolution is why snakes evolved their long, limbless bodies. A new study suggests snakes may have lost their legs at sea, before crawling ashore.
There’s a battle for resources going on in there.
Embryos greedily want more resources than their fair share. New research investigates how early in evolution their hormonal tactics arose.

A new study of the first ever snake fossil with legs suggests that snakes evolved on land rather than in the ocean, as previously thought.
Is one of President Obama’s SS agents a shape-shifting alien humanoid?
While it’s tempting to dismiss conspiracy theorists as nothing more than a loopy minority, on a growing range of contemporary issues they in fact make up a loud and vocal majority. Consider the nearly…

Invasive species colonize and spread widely in places where they are not normally found. Invasives often affect native species by eating them, out-competing them and introducing unfamiliar parasites and…
The sex and personality of lizards can influence their learning ability, new research shows. Spatial learning in male and…
Woodlands in the Australian subtropics could quickly become havens for native lizards if cleared areas are left to regrow…
It seems that not only mammals and birds are shaped by social interactions, with young chameleons showing their social development…
Them’s fighting words. And colours.
Humans have been fascinated by the colour-changing abilities of chameleons for a long time. Aristotle himself, the forefather of Western philosophy and also a keen zoologist, mentioned the lizard’s ability…
An observational study has found the Asian long-tailed skink (Eutropis longicaudata) will aggressively defend its eggs from…
Since the early 20th century, there have been claims that dinosaurs were warm-blooded.
Mark Twain reputedly said it wasn’t what he didn’t know that bothered him, but what he knew that wasn’t true. A recent contribution on dinosaur physiology in Nature, by palaeontologist Meike Köhler and…
Larger animals with longer legs aren’t always the fastest when sprinting, but then neither are smaller animals. Researchers…
