the.com/pill bug
A crustacean that lost the ocean but kept the armor, now rolls itself into a tiny panic button.
means A small land-dwelling crustacean (also called a roly-poly) with a segmented, armored shell that it curls into a tight ball when threatened.
from The 'pill' part is the old one — by the 1700s English speakers were calling it that for the simple reason that rolled up, it looks like a little medicinal pill, round and swallowable-seeming. 'Bug' got tacked on later as a catch-all for small creepy-crawlies, though pill bugs aren't insects at all — they're isopods, crustaceans more closely related to shrimp and crabs than to any true bug. The rolling trick itself (called conglobation) is an old defense borrowed from their ocean-dwelling relatives, repurposed for a life lived under rocks and logs instead of waves.
