18-Scorpii-4 Fauna: Decapods

The decapods of 18Scorpii form the most basal and least diverse group of Sherudobutsians (vertebrates), although fossil evidence indicates that during earlier geological periods, the group must have had greater diversity, perhaps even a form of ecological niche dominance (similar to Earth's dinosaurs).
The only surviving group of decapods is nicknamed: Squamata-Myriapod (code name: SQM).
This temporary name schematically describes the morphology of most animals in this group. They have a snake-like or lizard-like body, surrounded by five pairs of legs reminiscent of certain centipedes. Their jaws are short and possess venomous fangs like those of some reptiles, in addition to a kind of forked tongue that these animals use to probe their environment.
Most of the "crawler" species (the nickname first used to refer to SQMs) observed rarely exceed fifty centimeters in length. The species illustrated here was named "Red Head Crawler"; it was one of the largest species observed by the first naturalist expedition, which also discovered their pacifism, a stark contrast to their venom.
