It actually can curl all the way around and throw a jet of water forward.

Can you imagine that?

Cool.

So it creates these small little forward jets of water with its tail by sort of cupping it and curling it around with special muscles that most fish don't have.

And that fish can actually propel itself backwards with its tail fin.

Interesting.

That's the only one that I could confirm.

I found references to a couple of other ones like the boxfish and the cowfish, which may be able to do something similar.

But that's really the only one that really is clearly using its tail fin for backward propulsion.

It's pretty cool.

Yeah.

But I knew the big risk of this is the right for the wrong reason.

Because people say, oh, you can't swim backwards, even though you can.

But you guys actually got it for the right reason, which is that the snailfish isn't the first one.

But the snailfish itself, it's just passively swimming backwards.

It's not...

actively swimming backwards.

But this wasn't, what they did with the survey is they basically put cameras in the Arctic and then just, you know, gathered a ton of data and they found all kinds of weird stuff that they'd never seen before, you know.

So there's still a lot to discover, you know, if we just put cameras down there.

Yeah, as predicted.
