Creepy crawlies fascinate me - it must be all those legs.  Except for spiders as they are pure evil. OK, they do a great job eating all the flies but still, no need for them to chase me around the house!

Insects and spiders share some similarities such as an exoskeleton and their symmetry. This is because they are both members of the phylum Arthropoda (meaning jointed limb). 

here are over one million Arthropoda species within the subphylum groups of Uniramia, Chelicerata, Crustacea and Trilobita. These include insects, arachnids, horseshoe crabs, crustaceans and trilobites.

Arthropods are bilaterally symmetrical and each body segment may bear a pair of jointed appendages. They are covered by an hard exoskeleton, which serves as both armour and a surface for muscle attachment.   

The phylum includes carnivores, herbivores, omnivores, detritus feeders, filter feeders, and parasites in nearly all environments, both aquatic and terrestrial.
