Where do crustaceans and arachnids live?

Answer 1

Crustaceans primarily inhabit aquatic environments, including oceans, freshwater bodies, and some terrestrial ecosystems, often found in habitats like coral reefs, estuaries, and riverbeds. In contrast, arachnids predominantly reside on land, thriving in diverse habitats such as forests, deserts, and grasslands, although some can also be found in freshwater environments. Both groups are adapted to their specific environments, enabling them to exploit various ecological niches.
