Featured Creature Friday: The Erudite Echidna

Featured Creature Fridays are a new feature here on the Red Roan Chronicles blog… check back every Friday for new weird and wonderful facts about creatures you may or may not know. Let me know what you think, and if you’ve got a featured creature suggestion, post them in the comments!

Today I’m going to introduce you to a bizarre and wonderful creature called an echidna. If you’re anything like me, you’re aware of the existence of the echidna, but unaware of just how remarkably strange they are. (This is true of many things in Australia, but one of the nice things about echidnas is that unlike practically everything else in Australia, they are neither poisonous nor deadly.)

The echidna is a cute little spiny creature, sort of like the bastard lovechild of a hedgehog and an anteater. It borrows bits of its physiology from birds, reptiles, marsupials and mammals. It has multiple sets of sex chromosomes. It probably even knows Barry Manilow’s entire catalog by heart. Behold, the erudite echidna:

Aside from looking like the type of animal I’d really like to raise and train as some form of battle-beast — perhaps I could find a way to breed giant-sized echidnas and ride them into war! — the echidna is a rare and wonderful bundle of weird wrapped up in bizarre with a delicious topping of awesomesauce. For a start, the echidna is a monotreme — it’s a mammal, but it doesn’t give birth to live young, it lays eggs instead. The only other living monotreme is the platypus — we might get to that one later, but it seems a little cliché by now, so we’ll see. The echidna also has the most amazing and adorable skeletal structure. How can skeletons be adorable? I don’t know, and I didn’t think it was possible before I saw this echidna skeleton.

If there was a way for me to reanimate the skeleton of an echidna and take it for walks around my neighborhood on a leash, like something out of a Tim Burton film, I would do it. Just look at that thing. LOOK AT IT.

But we were talking about eggs, which leads us to echidna reproduction, which is where things get really strange. Echidnas like to form “mating trains,” where the hopeful males follow females around for days in a long “train” of echidnas up to 11 individuals long, and they do this for literally months on end, until the female is ready to mate with one of them. Or possibly several of them; apparently echidnas are “promiscuous.” They’re also only the second animal known to mate during hiberation periods or to reenter hiberation after mating. (There’s a quote in that link that says, “Thus the echidna mating system appears to be characterised by roving promiscuous males which guard promiscuous females before and after mating.” Oh science, you’re so sexy.) So basically, sometimes male echidnas wait until the females are hibernating, then they mate with them, guard them from other males, and thus increase their chances of successful paternity. Not cool, male echidnas.

When the female is ready to mate, she digs herself in at the base of a plant and waits for some action. All those males, meanwhile, dig a sort of circle-shaped rut in the ground around her, then use it as an arena to battle for her love, shoving each other out of the way until somebody emerges as the victor. So they sort of create echidna crop circles. But without the crop part. And with echidnas.

Now, I know what you’re thinking: that stuff’s not all that weird. Well hold on, people, because shit’s about to get real. Among the male echidna’s reproductive adaptations is a penis with a “quadripartite anemone-like appearance.” What does that mean, exactly? It means he has a four-pronged penis. When he mates, he uses two of them in the female’s two-forked reproductive tract. Then when he finds himself another woman, his other two penii are already ready to go. Also, he shoots “semen bundles.” Aren’t you just freaking fascinated right now? I hope you are, because there’s video. Of course there’s video. Science is taking advantage of all the latest advancements in technology to bring you more detailed information about the echidna and its penis.

The female gives birth to her egg directly into her pouch, where the egg gestates and eventually hatches a baby that’s called a “puggle.” I’m not going to show you a picture of a puggle yet. I don’t think you’re ready. It’ll come when you’re prepared to handle it. First, I’m going to tell you about echidna nipples. They don’t have any. So you might be wondering how on earth this amazing new puggle is meant to sustain itself. Luckily, female echidnas do have “milk patches” right their in their pouches, where milk essentially seeps out of their pores (echidnas have pores, apparently!) for the puggle to lap up. Genius. Once the puggle starts developing spines, the mom’s all, “Screw this, I’m not keeping this pointy thing in my pouch anymore,” and she digs a nursery burrow and leaves her puggle there, coming back to feed it every five days or so until it’s weaned, which takes about seven months.

So, have you prepared yourself? Are you ready? Have you reached a point in your life where you need to see what a baby echidna looks like? I hope so. Because if you’re not prepared, the cuteness of a puggle can be dangerous.

Echidna can be found in Australia and New Guinea. The short-beaked echidna found in Australia prefers a diet of ants; the larger long-beaked echidna, in Australia, uses a long beak to hunt for worms underground. It doesn’t just lap them up with a long tongue, though. It spears them like it’s harpooning Moby Dick. The long-beaked echidna therefore is the obvious choice for a personal guard and attack animal. I mean, if you have a worm problem.

Well folks, that’s our first Featured Creature Friday. I hope you’ll share these fascinating facts about echidna reproduction with all of your friends and loved ones, so that they might be better prepared when I unleash my army of ravenous trained attack-echidna upon the world. Stay tuned for next Friday, when I’ll be introducing you to another bizarre inhabitant of our planet. Like, even more bizarre than this one. But hopefully with more conservative sexual proclivities, because come on, echidnas. You’re just getting out of control, now.

  1. Nice one! Featured Creature Friday is a great idea, I’ll be sure to tune in each and every Friday. I love echidnas (and their distant relatives, the hedgehogs), they’re so cute and weird. I loved your descriptions. Have a great weekend!
