Crocodile Concepts

While examining the creatures in fantasy open world games I could determine a pattern about how they fit into the fantasy world. They are featured as part of my bachelor thesis artbook. Creatures exist that are purely within magical background of the world, like the upper Zipacna, the blue crocodile. The Tamazochin (the second one) is based off realities' myths, but takes legitimately part of the ecosystem, even though it is completely manufactured - it isn't part of the worlds magical systems. Algae crocodile, palm crocodile and turf crocodile are almost completely based off real life animals with small changes to fit them into the ecosystem.
