In total, there are six species: animals, gyroids, humans, mystical beings, snowmen, and spirits. Whereas most species do not appear to be speciesist and interact harmoniously among each other, some animal villagers make disparaging remarks to the player about being a human. It is, however, clear that the sentient species treat insentient species inferior to them, exemplified by the Museum displaying bugs and fish, villagers and the player keeping bugs and fish in containers in their home, and gyroids being used as furniture objects.
Animal species are easily the most prevalent series in the game and humans appear to be the rarest.
The following is a list of species of the villagers. See their respective pages for more information:
Alligators & Crocodiles
Alligators have been referenced as "crocodiles" and since there are no villagers classified as crocodiles, it is assumed these two species are merged for the purposes of species in the games. Like horses, the alligator classification includes at least one villager, Drago, who appears to be a dragon rather than an alligator or crocodile. There are 9 of these types of villagers.
There is a default bear species, but there are also cubs, which appear to be smaller versions of bears. Bears are the only species wherein smaller variants are considered their own unique species, e.g. Katie, a kitten, is still considered a cat. There are 16 bears, and 18 cubs.
Bears & Cubs
Birds & Subspecies
There is a default bird species, however, several birds are grouped into different species entirely: chicken, dodo, duck, eagle, ostrich, owl, peacock, pelican, penguin, pigeon, seagull, and turkey. Birds and owls are the only species in this group which seem to vary in sentience, exemplified by the difference between Twiggy and the Yellow Bird and Blathers and the White Owl. There are 89 total "bird" villagers.
Bulls & Cows
Deer & Reindeer
Dogs are the only animal species with significant variances based on their breed. In addition to the default dog breed, there are also akitas, bulldogs, chihuahuas, jack russells, poodles, shih tzus, and spaniels.
There are 27 total dogs.
Frogs & Octopi
Like alligators, the horse classification includes villager species who appear to be unique from horses. Examples include Julian, who appears to be a unicorn; Papi, who appears to be an okapi; and Savannah, who appears to be a zebra;
Ostriches & Sub-subspecies
Ostriches, considered a subspecies of birds, have sub-subspecies within them, making them the only group with a sub-subspecies. This group contains Flora, a flamingo; Julia, a peacock; Phoebe, a phoenix; Queenie, an emu; Phil, a ring-necked pheasant; and the cranes Blanche, Cranston, and Gladys.
Special Character Species
The following is a list of species of the Special Characters. See their respective pages for more information:
GyroidsMain article: Gyroids
The Gyroid species seems to vary in sentience, like the special character owl species and the White Owl. The vast majority of gyroids appear to be unable to speak or possess any awareness; however, some gyroids, such as Lloid, seem to be relatively self-aware and capable of holding jobs and performing tasks.
HumansThe player as well as, presumably, the player's parents are the only known humans in Animal Crossing series, though humans do sometimes appear on the television. Humans' appearance can vary widely with notable differences in skin color, hair color, and face styles. Cosmeticians such as Harriet can help humans edit their appearance. Mii Masks are cartoonish versions of the human appearance, and Miis, therefore, are not considered a distinct species from humans.
Mystical BeingsTwo characters in Animal Crossing, Farley and Serena, either claim to be mystical or appear that way. Whereas Serena states that she is a fountain goddess despite her appearance as a dog, Farley simply has no origin and may, therefore, be human, though it is clear he has the ability to use magic via his interactions at the Wishing Well.
Main article: Snowmen
Snowmen can be created during the Winter season by the player rolling snowballs on top of each other. There are four known variants of snowmen: Snowtyke, Snowboy, Snowmam, and Snowman. They refer to one another as family members, suggesting a consciousness equivalent to sentience, and, perhaps, reincarnation.
Spirits, sometimes referred to as a "specter", appear to be some form of the undead, potentially of the other species. Jack and Wisp are the only known sentient spirits, though Jack's species is sometimes listed as "pumpkin". Insentient spirits can be collected as items in-game, marking a difference in sentience between spirits similar to that of gyroids. Wisp and other spirits are only able to appear at night in the outdoors, but Wisp can be summoned via a genie lamp indoors.
