List of Species

This is a list of the species that can found within the universe of Siren and Sir.
== Rodents ==
Rodents appear to be the dominant species of Humanland and make up the majority of the population in Oakdale Wells. They are fully sentient rats and mice capable of speaking languages; including English and South Asian languages. 
=== Appearance ===
The rodents of Siren and Sir (rats and mice) that dominate the planet are anthropomorphic, bipedal creatures, with fur completely covering their hands and feet(unlike mice and rats in real life). They have only four fingers, unlike the five of their real life counterparts, as is common with animated characters. All have long, pink, hairless tails (which is mostly common in lighter furred rats and mice) with little to no variation, with unique noses of varying shape and size. They appear to be scaled similarly to humans and have varying heights depending on age and genetics. Their faces resemble humans far more than rodents, which explains their uncanny appearance.
Unlike rats and mice in real life, they are also capable of vomiting, having abs, and only have one pair of nipples, with permanently enlarged breasts.
Differences between mice and rats are superficial and barely plot relevant at best, though notable series characters of either group are Sir Mouse, a young mouse from a mouse family, and Mr. Tim, a rat.
== Cats ==
This species has only been mentioned directly once in the show by Kristen as a parody of the popular saying, "the boy who cried wolf". She warns her son Sir about, "the mouse who cried cat". Although the implication is that "cats" have a role similar to that of wolves in the show's universe, it could also imply that cats are the more dominant species than that of rodents, like the world depicted in that of Art Spiegelman's graphic novel Maus or the Geronimo Stilton series. (Note: This is not to imply that Siren and Sir is in anyway a commentary on religion, race, or politics in the way that Maus is. This is simply an example.) The common pun, purr-fect was also once used.
Cats have also been used as a metaphor for genitalia in the series.
Big cat, such as tigers have also appeared in the show, albeit as a part of Sir's medicated hallucinations.
== Farm Animals ==
A cow and pig have been seen in Sir's medicated hallucinations.
== Dogs ==
Dogs are a non-sentient species that inhabit Humanland. They are owned and trained the same as dogs in real life, though some show more intelligence and autonomy, as is common in cartoons. 
=== Wolves ===
It can be assumed that they evolved from wolves as they did in real life. The species was briefly mentioned by Sir. 
=== Appearance ===
They are identically scaled to the ones founds in real life. Some breeds of dog that have been seen are the Pembroke Welsh Corgi, Beagle, Pitbull, and Chihuahua. 
== Birds ==
Birds are a species that inhabits Humanland. A small blue bird can be seen flying in the opening shot of "Oakdale Wells Massacre", which suggests this is how they generally appear. 
=== Appearance ===
They appear identical to birds found in real life and scaled similarly, although these have eyebrows.
== Spiders ==
Spiders are a species of arachnid that can be found in Siren and Sir. Sir is frightened of them enough that Victor takes on that form in his hallucinations/dreams.
=== Appearance ===
The two spiders that have been seen on the show are Spider Victor and the talking spider in Sir's quarantine hallucination. The talking spider and Spider Victor are scaled similarly to real life spiders in their regular states. Spider Victor however, has grown to a much larger, more exaggerated size in Sir's dreams before. 
== Humans ==
The existence of humans in Siren and Sir is unclear. Although the dominant species of Humanland seems to be sentient bipedal rodents, humans have appeared (primarily in art form) a handful of times in the series. Either in illicit magazines, or in Sir's art, hung up on his bedroom wall. They are also the namesake of the planet.
=== Appearance ===
Humans appear identical to the appearance of humans in reality. The only difference is that a human face has never been seen in Siren and Sir.
== Horses ==
The single horse that has been seen in the series appears once as Sir's steed in a dream of his.
=== Appearance ===
Identical to that of real life horses, and scaled similarly. They're bigger than rodents but smaller than dragons. 
== Dragons ==
Dragons do not exist as a physical species in Siren and Sir. They appear in the same way that they do in real life, in books and fairy tales. In the story of Siren and Sir, they are the mascot of Oakdale Wells High School and appear as the manifestations of Sir's tormentors in his hallucinations/dreams.
=== Appearance ===
The blue dragons have not been seen from the neck down. They have long necks, completely black eyes, sharp teeth and light blue crystal fringes. They're a dark, murky blue overall.
Red Dragons have not been seen on the show.
