| All species are sleek, raptorial predators, relying on fast locomotion and large mandibles to actively chase down a variety of arthropod prey. |
| Fiddler crabs, like their arthropod cousins the insects, have compound eyes. |
| This insect is among the most damaging arthropod pests of pears in North America and Europe. |
| Major arthropod lines have long been recognized, but the phylogenetic relationships among these groups remain controversial. |
| The ecdysial suture is the region of the arthropod exoskeleton that splits to allow the animal to emerge during ecdysis. |
| It thus seems likely that the ancestral arthropod from which insects evolved had appendages on all its segments. |
