How woodlouse is different from a beetle?

Answer 1

Woodlice and beetles belong to different taxonomic groups: woodlice are crustaceans, while beetles are insects. Woodlice have a segmented, flattened body covered with a hard exoskeleton, often resembling miniature isopods, and they breathe through gills. In contrast, beetles have a more rounded or elongated body, a pair of hardened forewings (elytra), and breathe through a system of tracheae. Additionally, woodlice are typically found in damp environments, while beetles can inhabit a wider range of habitats.
