I assume the croc has been on it before and is like "death 1 inbound, reaching hunting grounds soon"

The further we get away from mammals or even more specifically the further we get away from humans, the more difficult it becomes to guess animal cognition.
Typical farm chickens seem to have cognition on par with 3-4 year olds
Typical dogs also about 3-4 year olds
Pigs rank to amongst the smartest nonprimates, doing better than dogs on cognition tests
Monkeys obviously seem to be on par from something like 4-6 year olds
Cats also difficult to guess , especially with their aloofness but seem to be from 2-4 year olds.

The progress on delving into the minds of animals is slow, but perpetually becoming better. See, we've only recent moved from the idea that animals are in this perpetual present and might actually have memories. We've even discovered that rats dream.

Of course, people tend to think of fish as dumb but the few people willing to explore their cognition are showing some fish can count -- which is remarkable given the best bat we've given so far is to dolphins which of course are mammals.

To answer your question, it's probably highly likely that crocodiles can entertain themselves. Most species we've observed [or at least, have cared to observe] seem to have form of 'play' amongst themselves, even if its something like wrestling

are you saying i aint smart?

Well, I mean, I'm sure they have fun eating stuff.

If he were upset, he would turn around or at least struggle a bit. My guess is that he either sees it solely as a mode of transportation or enjoys it, and considering how intelligent crocodiles are he probably enjoys it.

Well, maybe they're smarter than us then, not dwelling on the past and all

Truuuue. But it's a little different. I speak from my own experience. If my bearded dragon doesn't like being in a spot, he wiggles until he is out of the spot. But a bearded dragon who gets his tail bitten off doesn't really freak out.

Biologist's have found that mammals are the only creatures on earth that "play".

Really? I've seen at least two nature documentaries where they say that crows play - one was Nat Geo WIld's "Wildest Russia" I believe. Not trying to be confrontational, just wanna know where you read that.

I found this, too www.popsci.com/scitech/article/2009-06/play-unique-mammals which says that play is not unique to mammals

I was taught that back in grade school, so it might be outdated info.

I wanna thumb you down for being wrong but I know I have a few nuggets or grade school information that are outright wrong too. I think elementary school teachers just didn't check their facts

You are correct. mini-OP doesn't know what he's taking about. Crows and many species of birds play, as do animals like cuttlefish and octopi and sometimes even reptiles.

Read a book on octopuses recently. Turns out they're kind of like playful dogs of the sea. And hella smart too.

Well, if you look at the .gif, you'll see he/she keeps getting up and tries again, over and over. Must be having a blast!

My momma says alligators is ornary 'cause they got all them teeth and no toothbrush.

OH YEAH? WELL WHY IS SMILING!?

damn crock is grinning ear to ear
