arthropods

Advanced 🎓 Education / Academia

Definition

Invertebrate creatures with segmented bodies, chitinous exoskeletons, and jointed legs—think insects, spiders, crustaceans, and the occasional unwelcome houseguest. They make up roughly 80% of all known animal species, so basically, they've won evolution.

Example Usage

Arthropods are essential to every terrestrial ecosystem, from pollinating crops to decomposing dead matter.
