The Insane Biology of: Kangaroos

There is 48 millions kangaroos in Australia and 3,5 millions people is Uruguay which mean if kangaroos were invade Uruguay, each person will have to fight 14 kangaroos .

That photo of a Kangaroo just standing alone in the water, staring dead at the camera, is creepy as hell.

"Only about five people per year seek medical attention after a kangaroo encounter; the rest lie because they are too embarrassed about how they got into that situation."

13:10 "Male kangaroos will sometimes stand in ways that show off their muscles, to entice females..." Some things never change.

Kangaroos physique is so impressive to look at. Those poses where they show off their muscles, it reminds me of people at the gym who work out in front of mirrors, so they can see themselves. It is so strange to me that so many animals have muscles that are far stronger than ours.

The list of organisms that will make a good go of ending you in Australia is pretty impressive for its diversity; snakes, spiders, crocs, roos, wasps, emus, fish, sharks, octopi, ticks, jellyfish, bogans, sea snails, centipedes and even trees.

Had to rescue a dopey Japanese tourist once (Please note... I like Japanese people... but, this guy must have had rocks in his head)... he tried to walk right up to a 6ft+ male kangaroo, who was stooping to feed, and hand feed it. It stood upright, suddenly dwarfing this tourist, then raised up on it's tail for like a fraction of a second... then launched him for six. Folded him in half. He was lucky... it must have only given him a warning kick. I laugh about it now... but, I genuinely though he was a goner, when I saw him walk up to it.

One of the most scariest interactions with a kangaroo happened when I was younger and I was just walking around and then I look behind me and there’s one just standing there looking at me.

If you’re ever attacked; put your head down and cough loudly (it’s a sign of submission). The kangaroo will usually leave. They want to win not kill

One of those special features their anatomy has is the 'epipubic bone'. This is a special pair of bones that Marsupials evolved to support the weight of the pouch with a joey in it. They are mounted on the front of the pubic bones of the pelvis and then rise up to the middle of the abdomen (about where the belly button would be). In Kangaroos, these unique bones also have a second function. Aside from supporting a female's heavy pouch with young while bounding at speed, in males, these bones act like a second rib cage, forming a shield over the vital organs and allowing those horrendous kicks to divert off to the side rather than rupture the gut or straight up rip the belly open. Kangaroo hide is also exceptionally strong for its weight. Its valued as a leather for that incredible durability and lightness. This is also another adaptation to their unique lifestyle and environment. It provides exceptional resistance to scratches and tears in combat or the rough, twiggy forests on Australia, while not weighing them down when they need to travel fast. As a side note, the presence of epipubic bones is an instant identifier when determining if a fossil is a Marsupial mammal or a Eutherian (placental) mammal. Just a bit of trivia.

The most fascinating thing I learned from this video is the fact that a Roo’s niche is parallel to that of deer on other continents.

Kangaroos are the nature's way of telling you "Fuck around and find out"

7:22 "allows them to outrun predators" *Kangaroo running from a tiny bird 😂

Before i even watch this i already know just how dangerous kangaroos are. I knew an australian guy and talked with him about them. He had to save his dog multiple times from kangaroos that tried to drown it and he showed me pictures of those massive spikes for nails on their feet. Those are some scary animals.

Been face to face with one before, it's terrifying! They used to go through my yard past the side of my house. One night I heard something down the side of my house between the fence, so I went to check it out. Yeah a big buff kangaroo just stood there facing me when I pulled out the torch. Stepping back carefully was in order heh.

Looking at their little arms tucked up there like that reminds me of another animal. A big one. That's extinct. Imagine....if you dare ..a T Rex hopping like a kangaroo. Could it possibly be?

I'm graduating this spring in biochemistry and have always admired this channel. It's just criminally underrated, thr science is head and shoulders above other educators. And paired with good stock footage and fantastic narration. That taipan video was a layperson approachable explanation of a 400 level undergrad biochem lecture series, and didn't dumb it down at all. Apparently, roos are an amazing source of meat, too. Like 97% lean and far more nutrient dense than cow, pork or chicken, and somehow it's not tough or gamey, a buddy said it's like beef tenderloin. I haven't had a chance to try it yet, but roo steaks are high on my list of foods I'd love to try. Turn all the cheap ground beef in the world's fast good into impossible meat, give us roos as an alternative to beef in most other things (kangaroo fajitas), and save the cows for special occasions.

Just a few years ago I spent three whole days at Philip Island Wildlife Park in the off-season. Very few tourists but lots of Red and Eastern Grey kangaroos to spend time with up close and personal. One of my most treasured memories and the last item on my bucket list. Remarkable creatures and, in that environment, very friendly and not at all aggressive. Spending time feeding, stroking and talking to a mob of kangaroos in fields and an atrophied wood and creek, with no other human in sight, was food for my soul.

I was at the cemetery which has kangaroos all throughout and two of the big fellas started to kick off. The one who lost got pissed off and tried to pick on another one, which kicked his ass too. It's awful when they fight but seriously impressive. Joey's are so bloody cute the way they bop about. I've also seen something like 200 roos at least behind the local fire station just appear out of the long grass and take off in a mass migration. They blend in so well you'd hardly even know they are there. Roos and quokkas ❤ are some of the most beautiful creatures

My fiancée has 6 brothers who want to drown me. The kangeroo will just have to get in line.. 😂
