What new protections will mean for these widely hunted sharks The sharks and rays are widely hunted, their parts used in commercial products like makeup and moisturizers and in culinary delicacies.

Sweeping trade protections adopted for sharks and rays at #CITESCOP20.

“It’s taken 20 to 30 years to get recognition that sharks and rays — keystone predators in marine ecosystems globally — need that protection,” says WCS’s @lukedavid301.bsky.social.

A four-panel dashboard showing the Threatened Species Index 2025. Top-left: a line graph titled ‘Main index’ displaying a steady decline of 75% between 1985 and 2022. Top-right: a map of Australia with numerous points indicating spatial representativeness of monitoring sites. Bottom-left: a scatter plot titled ‘Monitoring consistency’ showing site-year observations over time. Bottom-right: a dual-axis chart showing growth in the number of taxa and number of time series per year from 1952 to 2022, both rising sharply before levelling off in more recent years.

Scientists Recreate Rare Pigment Behind Octopus 'Superpowers' Octopuses and other cephalopods are masters of camouflage, thanks largely to color-changing skin that can help them seemingly vanish into the background.

“A team led by UC San Diego was able to mass-produce a key pigment, xanthommatin, that occurs in the psychedelic skin of many cephalopods. Until now, xanthommatin has proven impractical to collect from animals or make in a lab.”

A small, wallaby-like animal stands on its hind-legs. Text overlay says: New science - Brush-tailed bettongs reintroduced to SA National Park after over 100 years.

🧪 Science Spotlight 🧪 Researchers have successfully reintroduced brush-tailed bettongs into a National Park, despite the presence of feral predators like cats and foxes.

Bettongs sourced from populations with larger body sizes and previous predator exposure survived better.

Jane Goodall said she would launch Trump and Musk on one-way trip into space Primatologist said in interview released after her death she would also put Putin, Xi and Netanyahu on that spaceship In a lifetime studying the behavior of chimpanzees, Jane Goodall became something of an authority on the aggressiveness of alpha male adults. Now, in an interview released just days after her death, the famed primatologist reveals what she would do with Donald Trump, Elon Musk and other human beings she saw as showing similar traits: launch them on a one-way trip into space. The insight into Goodall’s thinking comes in the Netflix documentary Famous Last Words, recorded in March and kept under wraps until her death last week at the age of 91. Continue reading...
