Anthromorphs comprise xenohumans biosculpted to resemble anthropomorphic animals, either as part of a fashion trend among glitterworld cultures or as designer mates suited to satisfy their masters' tastes. Apart from superficial skeletal alterations, anthromorphs' modifications are only skin-deep, meaning their capabilities are roughly the same as your average, baseline human. Anthromorphs are exceedingly rare on the rim - you're unlikely to encounter them beyond opportunistic mercenaries, travelling spacers, fleeing refugees, and fellow colonists.
Anthromorphs function roughly the same as humans. No unnecessary items or special race-specific mechanics, their only difference - besides cosmetics - is a slight beauty boost and marginal temperature preference shifts. You will still need to equip them with temperature-appropriate apparel, however. You can select which anthromorphs generate in the world in the mod settings; all generate by default.
