| Note that the male in the image at right has much larger eyes and raptorial appendages. |
| The creature was a quadruped, two appendages connected to the upper chest cavity, in a very mammalian like structure. |
| Their lethal raptorial appendages provide effective weapons for acquiring and defending these homes. |
| The only appendages that all crustaceans have in common is two pairs of antennae. |
| In addition, they have potent raptorial appendages, with which they produce extremely fast and powerful strikes. |
| It thus seems likely that the ancestral arthropod from which insects evolved had appendages on all its segments. |
