How did a toilet photo become a breakthrough for science? 📸🦦 @loarie of @inaturalist shares how a camper in a remote Colombian cabin snapped the first confirmed photos of a living Colombian weasel, a species once known only from 1800s museum skins. Uploaded to iNaturalist, the images turned a chance sighting into a major scientific moment, showing the surprising power of citizen science.

You can sort arthropods into four main categories: chelicerates, crustaceans, hexapods, and myriapods. (All are magnificent.)

We’re in the second-to-last week of our ID-a-thon, and we’re sorting arthropods! Here’s a quick guide to get you started: tr.ee/identifyweek4 🦀🦋🕷️

Consider your sign to stop and stare at logs a little more often because just LOOK at this glorious velvet mite! (Third photo is where it was spotted.) 📷 jeremyhegge on iNaturalist 📍 Australia 🔗: inaturalist.org/observations/3… #ObservationOfTheDay

Try finding a comfortable spot and staying there quietly for just ten minutes. It's worth it, we promise.

You don't need expensive equipment to get started! And your photos don't need to be perfect — even distant shots can sometimes help with identification.

Happy #NationalBirdDay! Wherever in the world you are, go admire some birds today (and share your photos on iNaturalist). Here are a few quick tips to get you started. 🧵⤵️
