And that's usually doesn't end well with the seal.

One thing that's crazy about these male-to-male conflicts is that when they fight each other, they essentially go after each other's baculums, which in carnivorans, carnivorans have a bone called a baculum in their penis.

So they go after each other's baculum to try to break it.

So it's pretty brutal out there.

Honestly, I have no idea how that compares to other mammals groups.

One of the nice things about sea otters is that they have to come to the surface and they just float.

So it's just so easy to get these observations because they're also really close to shore.

So like we were able to get these detailed information, whereas like other smaller animals, like even river otters, it's really hard to spot them and actually see what they're doing in the wild.

So who knows what they're doing out there?

Weird, wacky stuff.

Oh, there you go.

So there's these things called giant river otters in South America and the Amazon.

And these things are a little bit longer than the sea otters.

And if you ever see pictures of these ones, they are so weird looking.

They are another older lineage of otters that kind of offshoot from other otters like 10 million years ago or so.

But they got really like buggy eyes and they got their faces just like an alien otter.

But these guys are huge and they actually are in family units and they will actually go sometimes go after like caimans.

And there are even reports of them like fighting off jaguars.

Which is pretty crazy.

But yeah, the advantage for those guys is that they are in a group setting.
