I FINALY FOUND OUT HOW THESE THINGS, AND POSSIBLY ALL OTHER HERBS, STAY ALIVE ON THE ISLAND! I was traveling with my iguanadon, Indigo, when I spotted one of these. I was expecting a full rampaging killing machine flaying all of the creatures around me at the time. I have seen this before with raptors dillos even a spino! But, no. It was being peaceful. A lystro was right at the theriznos feet and she kept munching on leaves from a tree, like it wasn't there at all. Therizos must have a commensalism relationship with the herbivores of the island! For all who not know, and I do not blame you at all, commensalism is a relationship between species where one befits of of the other without harming it nor giving it an advantage. The theriznos are naturally hostile to predators, and most of the time can defeat them. Because of this other, more defenseless, plant eaters gather around the therizno so they can be protected. As Helena Walker said, “their are more predators than pray on the island.” This, in a normal ecosystem would mean that the wildlife would quickly murder itself. I believe that a therizno protects herbivores lower on the food chain, letting them breed and live relatively safely. The other plant munchers do not give the thirizno anything, because it can protect and feed itself just fine, but u do feel like theriznos are vital parts of the islands ecosystem.
