In a world full of noise, small wonders go unseen. One such wonder has crawled back into sight — a soft, slow-moving worm not seen for over 100 years.

Rare velvet worm resurfaces in Siang Valley
A team of researchers has rediscovered Typhloperipatus williamsoni, a rare velvet worm species. This creature, with velvety skin and stubby legs, was last seen in 1913. It was first found in Arunachal Pradesh's remote Siang Valley.

This worm looks like a mix of a slug and caterpillar. Its body plan has barely changed in millions of years. That’s why scientists call it a “living fossil.” For over a century, the species was only known through old notes and fossils.

From 2021 to 2023, experts from ATREE searched the valley. They followed old clues and historic records. After much effort, they found two living specimens. Their identity was confirmed using physical traits and DNA studies.
