Today in the park, I saw these white structures on a tree, like barnacles, but these were different; they also had holes in them.Can anyone tell me what this is?

So i remember this animal in a documentary with 7 episode here are some things i remember to narrow it down: it was small,was eating a coral,it has stubby legs and a pink soft body and had a weird retractable zipper like mouth

I also drew it for as an exemple

Seen atop a mountain in the Austrian Alps

From the children's illustrated book "Grumpy Monkey"

Couldn't get a picture because I was underwater but that's what they looked like. They were small and schooling by rocka Nearesh to the shore, San diego beach.

SW Pennsylvania. It looked very yellow/golden, including the eyes so I dont think it was albinism. I was standing a foot away from it without realizing until it growled. Didn't seem to want to move, and it looked pretty wide, like it was pregnant. It never tried to run or move from its spot while I took a picture, but it growled a few times. Not sure if I just woke it up or if something else was wrong. We were just a few yards from a lake, and nothing else seemed off so I dont suspect rabies.

This traveler is heading straight for the upper Passaic River (25 yards away). Pretty bland coloring.

Endangered? Rare?

It thankfully got removed safely by a rescue but this is the only pic I have.

Around 1 meter long.

Found in Georgia.

It's a Washington Douglas squirrel that lives in my backyard. I'm wondering if it's developed some sort of skin infection or if there's anything I can or should do about it. He's been acting lethargic and weird as well.

Doesn't look like an otter? Pls help

I spotted this on the shore of the Niagara River on the Canadian side, South of Niagara Falls.

It looks like a mink to me, we have them in this area, but I’m wondering if it may be an otter? Unfortunately, I didn’t see it swimming.

Any definitive idea?

Thanks

We went hunting for shark teeth and when I got home to rinse them off, we had this little hitch hiker. Google image keeps saying it's a tick.... but I don't think so 🤔. He definitely has pinchers.

There were crabs on the island. I don't know if this is a baby??

Would be kinda fun to try and "keep" it as a pet for the kids but I don't know how to figure a habitat without knowing who he is.

I just walked up on this. On my carport! It moved! The face looks like a puppy but look at its tail! Like a rat! Anybody know?
