Turns out animals are pretty gay and I, a pretty gay animal, wanted to make something for this pride month. So I picked the gayest animals I could to represent the Ls, the Gs, the Bs, and last but not least the Ts.

Lesbian: Whiptail lizards, an all female species of lizard that produce asexually via parthenogenesis. Fascinatingly, ovulation in the species is encouraged through mating behaviors with other whiptails. These reptiles are quite literally an all-lesbian species and are commonly referred to this way in the shorthand.
Gay: Chinstrap penguins, a species pretty widely known for displaying a lot - and I mean a LOT - of homosexual behavior, which includes mating and courtships. All penguin species (hell, all birs species) are pretty gay, but chinstraps are famously so given the widespread story of Roy, Silo, and their adopted, also same-sex attracted daughter Tango.
Bisexual: African lions, a widely adored species of big cat with unique social bonds and hierarchal structures. Males both in and out of captivity have been frequently documented to mate with not only females and also take up a sexual interest in unrelated males. Lionesses, strangely, display more same-sex attracted behavior in captivity then out of it.
Transgender: Clownfish, an easily recognizable and sought after species of fish that physically change their sex to better suit their social needs. Schools of clownfish are consistently lead by a dominant female. Upon her death, the most dominant male in the school will become female and take her place.

There's a lot that can be said about Gay Animal Science and how it's both evidence that gayness/transness isn't a whackass perversion of "the natural order" (read: being straight/cisgendered) but also that bigotry runs so deep we flip shit at the idea of animals doing stuff we don't like. See: George Levick hiding documentation on the same-sex sexual and courtship rituals of penguins for literally 100 years because it was "depraved" and considered too shocking for public release.

But what I take animals being absolutely flaming and adorable about it as is evidence that these behaviors and self identifications are just as naturally occurring as being born shorter or taller then someone else, and that biology does not agree that these behaviors are detrimental or harmful to the nebulous concept of The Herd. The social differences and societally imposed caste systems that organize people based on their sexual/romantic and gendered inclinations are more complex for humans, true, but at the end of the day you are what you are, and what you are is as beautiful and natural as anything else that hurts no one and fills your life with joy.
