Gursky's spectral tarsiers (Tarsius spectrumgurskyae). Native to Sulawesi. Nocturnal. Just before dawn, they sing territorial duets, then return to their sleep sites in dense vegetation or tree cavities. Threatened by habitat loss, agricultural pesticides, and predation by cats and dogs. Vulnerable.

When it comes to geometric intuition, it'd been thought that there was a line in the sand between monkeys & humans. But baboons can do some amazing stuff when nutritious fruit snacks are on the line! By @krcallaway.bsky.social, feat. @cantlonlab.bsky.social 🧪 www.nytimes.com/2026/07/21/s...

Our geometric intuition, long considered something that sets us apart, seems to be shared with other primates.

I remain endlessly in love with the fact that life has squirmed its way in between paper-thin leaves, layers of rock hundreds of feet below us, and single acorns. There are parasites that parasitize parasites and probably parasites that parasitize *those* parasites.

Acorn ants, Temnothorax curvispinosus, in an old acorn in Illinois. They need an acorn in a particular stage of decay, usually a year old and already hollowed out. If you're looking for acorn ants, you won't find them in the fresh ones.

Where I grew up, daddy longlegs were everywhere! And yet, no one seemed to know a damned thing about them. In fact, the one thing everyone "knew" -- that they're the most venomous spider on earth but can't bite people -- turns out to be not just wrong, but wrong in like 3 separate ways! 😂🧪
