The Echidna Is Australia’s Most Delightfully Different Mammal (atlasobscura.com)

I love the echidna. I did a science project on it in 5th grade. My mom helped me do a clay sculpture of it and I remember having a blast putting in all the “spines”. Was also an avid og sonic the hedgehog player so it seemed like these little guys were everywhere during that time.


They are super cute and I always get a kick whenever I see one on a walk. No idea why they are named after "the mother of monsters", early Europeans must have been on another planet

https://en.m.wikipedia.org/wiki/Echidna_(mythology)


Please don't kid these creatures. They're harmless.


"Get a kick" = "enjoy", not a literal kick.


I forget I'm not on Reddit, where my silliness would have gotten upvotes.


Haha, yes I thought so but my experience on hn is any humor gets misread so just felt like I needed to clarify in case anyone thought I was a monster who goes around punting monotremes.


Here in Tasmania I've stopped a few times to shoo them off the road, most effective way to date has been to wrap a towel around one and drag it. They don't seem to enjoy that very much at all, but I figure they enjoy being driven over less.

This strapline is bound to generate some... interesting Knuckles fan art.

I had the good fortune of seeing a female echidna, licking honey from a bowl held by a caretaker, at the Australia Zoo shortly before departing. They are truly fascinating critters, cute in their own way.


I just realized I hadn't heard/read that word - echidna - in about three decades. The downfalls of not watching TV I suppose. Looking at the pictures, they seem to be cute little critters. Wonder if it would be possible to befriend one


Since the last time you played a Sonic the Hedgehog game?



Fun science fact: the echidnas’ internal monologue is in the voice of Idris Elba.


'Here I come, rougher than the rest of them, The best of them, tougher than leather' - Sun Tsu, probably


Was once [ignorantly] trying to help encourage an echidna to get off a busy road next to my house, but it burrowed down into the cement curb gutter. It managed to use its quills to hold onto the cement, and there was not a chance of moving it. I couldn't believe how strongly it could hold onto what I thought as smooth cement.


As I commented elsewhere here, my current method is to get a towel around them and drag.

Might have to wait a few metres away for a few minutes, see if they continue in away from the road.


Nice work. A towel, that is is just about the most massively useful thing isn't it!


I see where you're going with this ;)


They're even different sexually.

Last year I learned from the mainstream media that echidna penises have four glans (heads). Researchers from the Universities of Melbourne and Queensland and Monash University studied the structure. An article [0] in Melbourne Uni's magazine gives a technical overview and refers to the peer-reviewed paper [1].

They only use two at a time. The researchers speculate that two can rest while the other two are in use, outcompeting proto-echidnas with fewer glans.

On a sad note, the research studied echidnas injured in road accidents, handed in to the Currumbin Wildlife Sanctuary on the Gold Coast, that had been euthanised. I imagine the numbers available are the result of the rapid urbanisation in the area.

they are quite common in Australia, saw a few earlier this year, by the roadside just rooting around in the grass. Don't seem to be too scared of humans either, I couldn't easily stooped and picked it up. Nice lads


We found one on a track near Willoughby Falls in Sydney and it didn't seem to care about our dog either. We kept our distance obviously, but it was in no hurry as it slowly ambled off the track.


yeah they are adorably unbothered by us!


What parts of Australia? I don't think I've ever seen a wild around Queensland. Then again, I am in a bit more of an urban area. I still see possums and wallabys quite often though.


saw one on a verge in NSW. In a park for sure, but not exactly wilderness!


I love those little dudes!

I just moved to Sydney and saw them at the Taronga zoo... and I'd never even heard of one before. Strangest little creatures.


If you've just moved to Sydney, then there's a reasonably good chance of spotting them if you live outside of the city itself and walk around near bushland.

The /r/sydney subreddit is regularly full of reports of people spotting them when the Echidnas are more active during mating season.


Great article. Australia has the best animals. Even a mammal with an extremely painful venomous sting (the platypus), a pain that's not relieved by morphine.

And the Tasmanian Devil, one of the nastiest looking little creatures on 4 legs I've ever seen.

[1] https://en.wikipedia.org/wiki/Platypus_venom


I wonder how real the "not relieved by morphine is", or what that means exactly. Looked into this a while back and only found this source [1]:

> Intravenous access was obtained and 15 mg of morphine was given slowly. Over the next five minutes very little pain relief occurred.

> [...]

> A further 7.5 mg of morphine was given intravenously 15 minutes after the first dose, but again this produced little relief. Over the ensuing 15 minutes a further 7.5 mg of morphine was injected intravenously, which eventually reduced the pain to a tolerable level.

https://www.researchgate.net/profile/Camilla-Whittington/pub... has a review of studies into the venom but the only source for the pain I’ve seen is the same, Fenner 1992.

That said, a decent amount of painful stuff exists in Australia, so I wouldn’t be surprised; https://en.wikipedia.org/wiki/Dendrocnide_moroides springs to mind.


Nasty? No!

They're adorable.

I advocate for their domestication to anyone who'll listen.

They're known to be very tame and friendly with in a short duration of repeated human closeness.

Sure, an adult Devil could bite your hand off, but so can a dog, and Devils tend to prefer already dead things.


Devils are apparently more bark than bite [1]

> Once deposited into a hessian sack for processing, devils tend to sit very still and let you do anything with them, including opening their mouth to check for devil facial tumour disease (DFTD) – all while wide awake and not anaesthetised! Every single person who has witnessed this incredibly calm, still behaviour from wild devils has been astounded at how easy they are to handle, how relaxed they appear lying on the biologists’ lap, and how biologists still have all their fingers after opening the devil’s mouth wide like a dentist!

Yeah, I recently listened to a researcher on one podcast or another who was saying this same thing.

I'm willing to bet all adult mammals will exhibit similar behaviour in the right circumstances for them, they had to have been capable of being passive and calm in order for their mothers not to kill them.


Poor little fighty bastards: https://en.wikipedia.org/wiki/Devil_facial_tumour_disease.

Human efforts at eradication left them with such low genetic diversity that contagious cancer became a thing.

https://www.aussieark.org.au/tasmanian-devil/


Yep, that's the primary driver for my advocating their domestication.


OK, well, each to his own. Everything in Oz can kill you anyway :)

My "contact" was limited to watching one run around and around his cage at some zoo or animal preserve. He certainly looked plenty pissed off.


> run around and around his cage

> He certainly looked plenty pissed off.

Wouldn't you?


All of the animals could reasonably be pissed off, but some are resigned to their fate.


This parody right?

Devils are know to bite their own family’s faces off. Even people trying to conserve their population dislike handling them directly.

They are horrible critters … they don’t seem to serve a purpose in the wider ecosystem other than nastiness…


No parody, they're typically ultra calm when they're being held, and generally love play.

are you talking about domesticating a Tasmanian Devil or a Platypus?


It seems clear they’re advocating for ‘devils.


Thank you Sega for introducing me to the Echidna (sonic & knuckles)


Wtf is this doing on obscura? You are acting like they are extinct or extremely rare. They are very common in certain areas. They are fun to flip over.


Please don't do that. They don't like it.


Sure, we have come across them within a kilometre from my home. But 99.9% of the world don't live where echidnas are, and they have very distinct anatomy and habits
