The wohklukkadri yikikikla, or mantle lizard in Basic, was a species of small reptile that inhabited the lower levels of Eniam's crust.
The lizards had dark gray skin to blend in with rock. Cold-blooded, they stayed in lower levels or halfway down tunnels to magma, where they could geothermally maintain a comfortable body temperature. They also fed primarily on the magma's bacteria and deep-growing fungi. The slow but hardy wohklukkadri ikarkohs often competed with them for food.
They had large, black irises and pupils, but could stand brighter light than most cave creatures due to their lifestyle. Exotic pet owners discovered they could live in various homes and feed on fungi and pellets.
However, they found problems mixing them with other lizards. Although the mantle lizards were placid and peaceful, their instinct to gape at the colors red and orange would often provoke lizards who displayed such colors. Territoriality issues were only escalated by the simple-minded reptiles mistaking chin-flaps for bacteria-rich lava.
