Rubber Ducky Pill Millipede (Hyleoglomeris cf Bomba)

A pocket-sized armadillo in duckling yellow

Hyleoglomeris cf Bomba, the Rubber Ducky Pill Millipede, is small, round, and frankly adorable: soft duckling-yellow and black, and when something startles it, it folds into a perfect little ball, hence “pill.” Pill millipedes are their own order (Glomerida): they behave less like the long train millipedes and more like a chunky terrestrial isopod.

No bite, no chemical defense, just that flawless roll-up, which makes it a brilliant, safe show-and-tell animal for kids. It is a humidity-loving little detritivore: a damp, leaf-littered, rotten-wood setup is the whole plan, and it will quietly potter through it recycling the bedding. Charming, harmless, and a great change of pace from the long-and-leggy crowd.
