Hexecrawlers were about 50cm long and weighed 12 kg. They were descended from analogues to terrestrial catfish, bottom suckers that eventually turned to life on land as the rivers and swamps they inhabited often dried up and they came to live more and more off the nobby plants that crawled across the land with six legs. They are sluggish creatures that gorge themselves on plant matter. The transition took about six million years, but in the end resulted in a highly successful species. It's barbels were adapted to better bring food into it's mouth. They have no predators on land, but they routinely have to return to water to keep their skin moist and there are a variety of large aquatic predators that lurk in the waterways, some of which can follow them onto land for a short while. Even so their numbers became prolific. There numbers repeatedly rising and crashing from famines caused by overgrazing.





On a distant planet life emerges. First as microbes in the seas, then some of said microbes develop photosynthesis filling the atmosphere with oxygen and spurring the development of those creatures that ate them. Some of which clustered together and became multi-cellular creatures. Eventually some of the photosynthetic microbes evolved mechanisms to survive in swamps which periodically dried out and developed mechanisms to survive out of water. Those that did eventually refined their methods to live out of water. First as slime on rocks and mud, then as waxy slime and eventually as primitive plants. These plants would in turn be exploited, first by small radially symmetric four limbed creatures that would evolve four wins to allow them to pinwheel through the air, double shelled creatures with eyed tentacles growing from between their shells and a few other simple forms of life, but eventually a larger creature would take to the land, a rough analogue to terrestrial vertibrates that eventually yielded a primarilly land dwelling lineages: the Hexecrawler.
