18-Scorpii-4 Fauna: Ungulated Hexapods

Among the dominant group of megafauna in 18Scorpii, a group of hexapods has followed an evolutionary path that has led them to possess certain similarities to ungulate animals found on Earth. They are recognizable by their more massive bodies, supported by short, robust limbs ending in hooved toes and a kind of pad on the palm.
Despite these recognizable characteristics, their code name was inspired by the general morphology of these animals: "SUG," for Suidae-Gryllotalpidae. The reason is that hoofed animals vaguely resemble pigs or related animals, and their clawed forelimbs are often used for tilling the soil, like mole crickets.
Research suggests that the oldest subgroup of SUG is the group nicknamed "Hippo." Obviously, this nickname refers to Hippopotamuses and not the Latin prefix designating horses. These semi-aquatic animals have clearly undergone a similar evolutionary convergence to Hippopotamuses (without the territorial aggression). Interestingly, their forelimbs have evolved into hand-like structures to move debris and other obstacles from their aquatic beds.
The second subgroup of SUGs is nicknamed "Bumper" for an obvious reason. These animals, while physically more pig-like, share some similarities with animals that fight using horns or their skulls, such as ibex, rams, and other pachycephalosaurs. Equipped with robust heads and cranial horns whose shapes vary from one species to another, these territorial animals live in groups and regularly engage in fights, including their signature headbutt.
The last subgroup is undoubtedly the most representative of the code name chosen for them. Easily recognizable by their large, crushing jaws, maxillary horns, and forearms equipped with long, robust claws, these "Hogs" are found in almost every habitat! Using their claws to turn over the soil in search of roots, eggs, seeds, or animals, these opportunistic omnivores are not picky eaters and adapt to almost anything (even the survival rations of one of the research teams). It should be noted that these animals can be extremely dangerous; if they feel threatened, their long arms are far more deadly weapons than their impressive jaws.
