    [Image Description: Two pictures, the first a photograph of a spotted hyena female with two of its young, and the second a lateral view of a hyena female, showing the anatomy of its reproductive organs, including its large psuedo-penis.]

    Female spotted hyenas have unusually high levels of androgen levels, thought to be responsible for the masculinization of their behavior and appearance - most notably, to many people, in the presence of a clitoris so large as to be considered a pseudo-penis. 

    Females, being larger, more muscular, and more aggressive than the males, are effectively “in charge,” a status which carries over into mating. Their pseudo-penis is in fact a clitoris, significantly by high levels of androgens (hanging down about seven inches from the body), which is hollow and also functions as a birth canal (a complication resulting in an extremely high death rate of their young).

    Because of the shape of the clitoris, copulation is difficult - and forced copulation essentially impossible. To successfully mate, the female must be complicit, and aggressiveness, unlike in many other species, is not a guarantee of attractiveness, and those males which are more cooperate and submissive have a higher chance of mating than those which are aggressive, pushy, or rough. 

    this is such a weird thing to reblog

    oh well, it’s interesting

[Image Description: Two female whiptail lizards engaged in pseudocopulation, one on top of the other.]
Certain species of whiptail lizards, lizards native to the Americas which form the family Teiidae, are all-female, and produce by parthenogenesis. 
These species are the produce of crossbreeding between different species of whiptail lizards. Unlike other crossbreeds, they can produce viable offspring, and so so by asexual reproduction, producing eggs which, without being fertilized, develop as perfect clones of their parent. 
Despite the ability to reproduce without sexual acts, however, many of the females in these species will engage in pseudocopulation, mimicking the acts performed while mating between males and females of closely related species. Depending on their relative stages in their ovulation style, the two participating females will assume different roles. The female closer to ovulation will have higher levels of estrogen, and the one further will have higher levels of progesterone, and the relative hormone levels dictate whether the participant will take the submissive or dominant role. 
Females who have been mounted and engaged in pseudocopulation will produce more offspring than a female who had not.

A rare half-male half-female butterfly has been born at the Natural History Museum’s ‘Sensational Butterflies’ exhibition.
 
Known as a gynandromorph, the Great Mormon butterfly has one side of its body which is female and one side which is completely male; from the wing colour (the more colourful right side is female) and sexual organs, even down to the length of the antennae. You can see a line down the middle of the butterfly’s body separating the two.
 
Gynandromorphy is caused by the butterfly’s sex chromosomes failing to separate in the fertilised egg. It can occur in several species, including crabs and spiders but the condition is extremely rare.

Some parts of the Whiptail species have all-female populations. One  female lizard will lie on top of another and use sexual stimulus in  order to produce eggs which are clones of the mother. Lesbian lizards.
I am definitely the newest addition to the Whiptail Lizard fan club.

[photo of two rats, sitting in a cage. One is white and is looking at the camera, and the other is a bluish gray color and is sitting next to him looking to the side]
These are my rats, Mamba and Little Blue. They are a gay couple. How do I know? They spend all their time together, watch each other work out, and cuddle with each other. Also, they have sex every night in a cage right next to my bed, while I try to sleep. I’m not kidding. I see Little Blue humping Mamba when I turn on my light to see why the cage is rattling so much. Leave it to me to get the most horny, oversexed rats that keep me up half the night before finals week. 
As I was asking my mom to PLEASE move them into another room so I could get some sleep my sister said, “You’re kicking them out because they’re gay? We didn’t do that with you” (I’m a lesbian :D)  I said “I do not keep the family awake with my loud lovemaking!” My mom chuckled into her coffee and said “No, you save that for when we’re out because you think the neighbors won’t complain.” 
The rats are still in my room. I cannot bring myself to move them, so I’ve been sleeping on the couch. Recently my sister said “So now, you’re avoiding them? That’s just as bad!” I threw something at her.
