First off, remember that they are ALIVE, they are creatures designed to operate and/or look like a tool, weapon, or garment. They are not necessarily intelligent or possess psionic abilities, some are just dumb animals or plants with a little something extra. They are bio-technology. Before Athas even came out, I made up a race that had living technology. They had sea mollusks that they wore as armour, basically parasitic abalone shells that were as strong as steel. They had giant spiders that used their webbing to create solid walls to construct buildings. Each house had a creature like a giant clam that was used as a toilet because it was designed to eat waste. Be creative...
