The most widespread species are these flying lizards, given that most of the continents have a very warm temperature and environment which allows them to survive without being too complicated.
These Kiseilians have no fur, but they are smooth-skinned, only covered by a natural grease that keep their skin always hydrated and waterproof. Their skin is extremely sensitive in case of lacking of that grease, and they could scorch themselves.
Tropical kise are one of the most "delicate" species but also among the most beautiful thanks to their bright colors and very particular color combinations.
The ears and their tails are very particular: although there is a very common and widespread typology, there are some individuals (especially wild) with the most disparate and incredible forms.
This species has a large availability of food, so they tend to eat a bit of everything that is placed in front of them: meat, fish, insects, animals of dubious origin... as long as they look tasty they can be their lunch. As mentioned above, they will sometimes enrich their diet with fruits and plants if they feel or need it, but obviously they have a carnivorous/fish-eating base.
