#6 Phylum Arthropods

There are more arthropods than any other group of animals, so they are
divided into classes:

Insects, Crustaceans, Arachnids and Myriapods.

4 classes of Arthropods

1. Insects

Insects are a very successful group, due to their exoskeleton and tracheae,
which are very good at stopping water from evaporating from insects’s body,
so they can live in very dry places.
