There are a large number of demihuman species, and subspecies, but they can be divided into nine major groups.

Lamias: Snake girls, they don't have legs but rather an enormous tail. Sub-subspecies include medusa, medusine, echidna...

Beast people: They have subtle animalistic features, such as ears, arms, and tails. This group includes wolf girls, kobolds, tiger girls, satyrs, minotaurs, rabbit girls, pig girls, horse girls, and various types of insects. Unlike the Taurus, they are bipedal.

Taurus: From the waist down, they are a unique animal, for example, centaurs, who are half horse underneath, or Arachne, who are part spider. They are not bipedal, but rather have two arms on their human side, and the number of legs depends on the animal.

Slime: very moldable and adaptable jelly-like girls, in various colors.

Demons and angels: They usually have wings and horns, of different types, like imps or demons, also the large and muscular oni

Flying creatures: characterized by slender bodies and having wings instead of arms, like dragons and harpies.

almost human: very similar to humans except for some particular traits, whether their large size (giants and ogres), special features (cyclopes or monkey eyes) or their powers (Witches, Banshees, Zombies, dullahan)

Plant: These are part plant, like the dryads, the barometz, or the alraune

Sea peoples: Mermaids and their derivatives, such as mermen, shark mermaids, and scylla. They usually don't have legs and move very clumsily on land, but they have amphibious adaptations.

Based on the anime Monster Musume. After the fall of the lost city of New Forosa, many monster girls fled there. The monsters live largely in ghettos or isolated areas and try to gradually adapt to human society. But the process is slow, and they suffer a lot of discrimination.
Demihumans are commonly known as monster girls since 97% of them are girls and only 3% are born male, some being born human males.
ADIE is the organization that monitors monster girls
