I knew about fish sleeping and snakes having two penises(Hemipenes), but they only use one at a time.
I did not know about Koala fingerprints.
There are many odd things about animals that we still don't know.

That barking cat was a revelation!!
I had heard about the Koala fingerprints before. I wonder if they are all different like ours.
And of course other animals are ticklish!
Anyone who's played with a dog can tell you that. Guinea pigs are too, very much so, in some cases. Our hamster was too!

It's always fun to discover the unknown isn't it? I will have to go back over those weird facts. My memory isn't so good so I have to read things twice at least.

I still love fish sleeping. I discovered that when I had a large tank of goldfish and koi. I got up during the night and found they were all on the bottom of the tank asleep. It was really funny to see them.

I had fish and saw them sleeping too at the bottom of the tank.

Until you saw the fish sleeping did you even guess that fish slept. I don't think I even thought about it.

I certainly never thought about koala fingerprints.
What else is out there that we don't know about?
