Crustacceans Description Crustacceans have two pairs of antennae while myriapods only have one pair. Example of crustaccean will be lobster and woodlouse.
Arachnids Description Arachnids don’t have antennae like myriapods and crustacceans. But they have four pairs of legs instead. That means it has 8 legs in total. Good example of arachnids will be spider, mites, ticks and scorpions.
Insects Description Everyone knows what is insects and in fact, everyone can compare what is insect and what is animal easily. Insects have one pair of antennae, three pairs of legs and two pair of wings. And if there are three pairs of legs, it means there are 6 legs in total. And all the insects can fly. Warning : Spiders are not insects! Spiders cannot fly!
