In honor of World Animal Day, which I don't otherwise care about, Broadly is sharing some animals that can change their sex or are both male and female at the same time. It might seem a bit of a stretch to relate animal life to human politics, but to quote what some MRAs trolls have shouted at me on Twitter, "biology is biology." These people often argue that there is an absolute biological distinction between males and females, and that's simply not true. Humans have many areas of overlap when it comes to biological sex characteristics, and in the animal kingdom, lines can blur even more. People often find it easier to empathize with dogs and stuff like that rather than other people, so let these animals be your guide to understanding this concept.

Regarding sex-changing animals, the technical term for this phenomenon is sequential hermaphroditism. It generally goes one of three ways: Males can turn into females (protandry), females can turn into males (protogyny), and bidirectional or simultaneous sex change, where the animal is both male and female simultaneously, altering between the sexes at different points of its life. Such activity is particularly common among fish.Dr. Scott Heppell of Oregon State University says that the phenomenon of sex-change among some animals can be advantageous to the species. Speaking specifically about fish, Heppell told Broadly that "there are several families of fish that have sex changing species, so it is far from uncommon."Sometimes the changes occur because mates are hard to find, so the animal makes its own, or it can be an issue of size. If you can't successfully reproduce as a male when you are small, then you can maximize your lifetime reproductive output by spawning as a female," Heppell says.Fish are most commonly talked about for sex changes— The New York Times reported on the prevalence of fish sex changes as far back as the 80s, but it is also possible in other groups. And in addition to animals that can change their sex, there are animals that are both male and female at the same time, or that have naturally occurring aspects of the opposite sex. Here are some of these atypically sexed animals.
