Birds do it.

According to Cole Porter, bees do, too, but it’s not exactly what he imagined. Wild and tame, avians, insects, and mammals all have sex – although not always as you’ve been told or for reasons you might think. Even educated fleas do it and, as in the new book, “Poking the Squid” by Perrin Roosevelt Ireland, humans can learn from them all.

If you read through scientific papers on animal reproduction, you might notice something unusual: for scientists, the word “sex” means a lot of different things.

Says Ireland, “It’s used to describe behaviors, biology, life histories, and more.”

That might be because animals are not simply binary. 

Take, for instance, hyenas. It’s easy for the casual observer to mistake a male hyena for a female and vice versa because of stereotypes of anatomy. Mating, for hyenas, requires subordination for the male and a nifty trick on the part of the female’s body to get things done.

Our feathered friends are no birdbrains, either: black-browed albatrosses were once thought to be monogamous but global warming seems to have changed their nesting habits sometimes. Male flamingos have sex with one another, as a territorial thing; other birds and animals form same-sex pairs for other reasons.

The Chinese mantis eats her mate after fertilization. Female snakes, alpacas, guinea pigs, and monkeys are anatomically able to enjoy sex. Genitalia between species varies quite a bit; in fact, the vaginas of ducks “are highly complex.” 

Lionesses will mate up to a hundred times when in heat. Female damselflies will change into a “third sex” to avoid overly-aggressive mating males. Bearded dragons can change their sex, if needed, as can yellow clown goby fish. 

And seahorse pregnancy and birth sparked a book-banning in Tennessee. 

So, asks Ireland, if animals, including us, vary so much in biology and life, “… why are we using the word sex like it means something, anything, consistent?!”

Pick up “Poking the Squid,” page through it a few seconds, and you’ll see that the information here is largely told through cartoon-like drawings mixed with captions. It seems to be something on the lighter side, but don’t let that artwork fool you.

Author Perrin Roosevelt Ireland offers readers solid information that cozies up to the scholarly, with hard science, philosophy, feminism, and quotations from researchers to support it, thus furthering the narrative and hitting the points squarely. If you see the art and expect something lighthearted, comic, and small-talk-worthy, you could be disappointed. 

On the other hand, if you want solid, wryly-serious facts, you’re in for a treat.

There’s lots of learning to be gleaned here, and some slight nudge-wink whimsy to emphasize the absurdity of wrong-headed thinking. This can make readers feel like they’re in-the-know on the jokes, and the playfulness balances the seriousness of the information well. 

So, serious, scholarly, or slightly silly, none of these are negative but you’re going to know what you want from a book like this. For the right reader, someone in the mood, “Poking the Squid” is wild.
