But so the hyoid bone is what's making the roar?
15:58
So let's see.
15:59
Tigers don't truly purr.
16:02
Obviously, they can roar, but they do something called like a chuffing.
16:05
And we often see it when they interact with humans in a captive environment.
16:08
But they do still chuff at one another.
16:10
And it's kind of like this rolling.

But yeah, how are they learning how to survive on the side of cliffs and bounce around being so cute?
48:24
That's really cool
48:25
...
48:25
I, I think my favorite thing about snow leopards, though, has to do with their, their physiology.
48:31
So if you, um, well f- take your tongue, if you're listening, take your tongue and rub your tongue on the back of your canines, so y- the sharpest of your teeth, your top teeth.
48:41
The back of your canine is going to be relatively flat.
48:45
The front of your canine is relatively rounded.
48:48
That is a characteristic that all, uh, animals, all species, all mammals that, um, or I, I guess, I don't know about, or about reptiles, but in the case of mammals, all mammals share this, uh, this common fact, because our, those teeth are designed for shredding meat.

Sure.
11:52
So Imogene, you want to cut in and give us a little feedback on this first story?
11:56
I think so.
11:56
Yeah.
11:57
So crazy story going from one corral to the second.
11:59
But unfortunately, what we're looking at is always going to be a case of where did human wildlife interaction go wrong? Well, not wrong.
12:08
You can say wrong.
12:09
So in the case of like, you know, feeding wildlife, obviously clear cut, like don't do that.

Which one did the common ancestor have? Was it stripes or spots that they started from? And how did they end up developing those spots like the other leopards did while the tigers have stripes?
