The Reason These Poisonous Butterflies Don’t Mate Is Written in Their DNA

About a decade ago, evolutionary biologist Richard Merrill would spend several hours a day in “hot, steamy Panama,” sitting in a cage filled with Heliconius butterflies, waiting for them to have sex.

Sloths Don’t Just Live in Slow-Mo, They Can Put Their Metabolism On Pause

Sloths’ reputation as lazy, slow and stupid creatures owes much to French naturalist Georges Buffon, who described the tree-dwelling mammal as the “lowest form of existence” back in 1749. Buffon’s assessment has endured for centuries, but much of the criticism directed at sloths is unwarranted. As zoologist Lucy Cooke explains for The Day, the sloth’s sluggish lifestyle is a deliberate survival strategy that has enabled it to maintain a place on Earth for nearly 64 million years.

Plan to Build a Genetic Noah’s Ark Includes a Staggering 66,000 Species

An international consortium involving over 50 institutions has announced an ambitious project to assemble high-quality genome sequences of all 66,000 vertebrate species on Earth, including all mammals, birds, reptiles, amphibians, and fish.

What are the smartest animals in the world and how do we know?

Frog skin secretions offer the first ray of hope in a deadly fungal epidemic

The early 2000s were a great time to study amphibians in Panama. At night, dozens of species sang out in chorus while researchers measured and photographed frogafter frog, often hiking to remote sites hours from the nearest road. Jamie Voyles and Cori Richards-Zawacki were both graduate students at the time, just at the start of their scientific careers, and Panama’s amphibians offered a plethora of research possibilities.

What’s the Filthiest Animal?

Ever since the 19th century, when disease was first linked to sewage-contaminated water, humans have gone to great lengths to escape their own filth. Meanwhile, animals have gone on reveling in the stuff—eating it, strategically dropping it, flinging it around just to pass the time, etc. Same goes for mud, piss, vomit, blood and rotting carcasses of every make and vintage. Most creatures just don’t have our hang-ups.

A fish that barely sleeps could help turn humans into all-night party animals

There’s something about the blind Mexican cavefish that will make you quite jealous: To survive and thrive, they require just two hours of sleep each night; no more, no less. Imagine everything you could do with those extra six hours.
