I'm working on a creature that lives in ant-like colonies. I'm attempting to combine some ant, crab/lobster, spider, and rhino features into this thing. The idea is that they'll have a hive mind, becoming more intelligent in larger quantities, and have a set of legs that are adapted mouth pieces and manipulators. There will be flying drones, queens, and several other castes. Also, they are going to have insect and mammal slaves (including people) that they herd or force to labor.
