[quote=RAINDROP,504984]Wan, The insect is a kind of animal, I think. The animals are divided into two kinds: one with a backbone and one without a backbone. The first kind includes fish, amphibians, reptiles, birds, and mammals. The second kind includes worms, sponges, mollusks, insects, etc. According to modern biological classification, there are eight major taxonomic ranks (domain, kingdom, phylum, class, order, family, genus and species). As you can see it, the animal kingdom has phylum, class, order, family, genus and species. The insect is a class of invertebrates within the arthropod phylum under the animal kingdom. Sunnydream just didn’t specify it clearly.[/quote]
