Overtime, some Unguliserds would wander into the more open spaces that make up the "Dingus Scrub", where they had plenty of vegetation to feed upon by also less cover to hide in. As such, these populations evolved even more towards speed and gave rise to the Liserlap, the first true fleet-footed herbivores to have evolved on Dingus. The Liserlap's legs have become much longer so they can cover more distance in a single stride while the anus-tail has become even longer for better balance as they make sharp turns. The hoof on the end of each of the Liserlap's legs have become much larger to better support a creature of its size. While the Liserlap enter the Dingus Forest to feed on new growth during periods of heavy rain, the species has primarily adapted to live in the "Dingus Scrub" and thus only rarely enter the interior of the Dingus Forest and they don't even try to enter the constricting environment that makes up the Dingus Jungle. Without the constraints of dense jungle limiting their size, the Liserlaps have also become much larger than their ancestor so they can better digest the vegetation they consume. Speaking of which, this species has evolved a unique solution to dealing with tough vegetation which gives them a slight competitive edge over most turdles(the only other group of major herbivores on Dingus). For one thing, the Liserlap has slightly mobile lips to help aid them with manipulating bits of flora so they can be kept in their mouths. Meanwhile, the throat has evolved strong muscles that allow it to be compressed inwards and pushed up, allowing it to act like a rudimentary tounge. This "tounge" is lined with large grinding plates, derived from the same spines that gave rise to the teeth that line both the upper and lower jaws, and together these tough structures help the Liserlap grind up flora into a pulp before they are swallowed so they can be more easily digested. With this adaptation, the Liserlap makes quick work of small nomflora, canarflora, and poralps that live within the "Dingus Scrub" and additionally allows them to better process the local Pissflora. As such, the Liserlap feeds upon the pisstowers more often than the majority of the local turdles, although they are not specialized for such a diet and thus avoid competition with the Piss-Chomping Turdle which is a pisstower-specalist. Living in more open conditions meant the Liserlap developed camouflage patterns that better fit them living within the "Dingus Scrub". The wide open spaces meant the Liserlap could more easily spot threats like the occasional Bug-Upper, so they did not need to rely as much on foraging at night. While the infrared vision still helps them with navigating their environment at night, the Liserlap now spends more time foraging in the day time. Traveling in decently-sized herds, the multiple Liserlap individuals will spend their time switching between foraging and observing the landscape to spot potential dangers. Sometimes these herds will travel alongside species of turdles like the Lawnmower Turdle as the large size of these herbivores can help deter threats from approaching while the Liserlaps feed on the small shoots left behind by the grazing giants. Since their radiation organ has long since lost an viable usage, it has become extremely small and is no longer capable of even shooting a laser, some individual Liserlaps don't even possess the organ which is not too dissimilar to the condition of wisdom teeth in Terran humans. The small hump of their ancestor has become a large brightly colored sail with tall osteoderms that the Liserlaps use to communicate with one another. It also is used to show the fitness of an individual and as such is used for courtship during the breeding season. The Liserlaps still utilize sexual reproduction, though they only do it when the rains arrive within the "Dingus Scrub" so the produced young have an abundance of vegetation to feed upon. The way they breed has not changed at all though, with two individuals budding next to each other that then merge together and exchange genes. Then, the Liserlap pair also irradiates the buds to help further mix up their genes. Then, the merged bud would split into 4 genetically distinct offspring. This allows the Liserlap to quickly adapt to any changes in their environment, such as an unusually long drought or extra heavy rains resulting in abundant flora growth.
