sure looks like a salamander.

This is a species of dragonfly in its aquatic larval stage.

Here's a link to a google image search (but without much finer detail on the photo there's no real way to identify the species). Someone may be able to get you a genus, but that someone isn't me.

This is a water lily in the Family Nymphaeaceae.

I can't get you any more resolution than that, but someone else may be able to.

Astonished?

Thanks BugEric! You gave me lots of good suggestions, but I'll just thank you here.

I know this is a fairly simple ID, but I can't ID my birds without a field guide and I simply didn't have one on hand. So thanks much Jakubko (and everyone else who chimed in).

Thanks. I will check up on that, though it's probably so.

Ali Hemati Pour, you are very welcome.

However, I am not sure I understand the question. C. fluminalis belong in the wilderness right where you find them. They are a normal part of those ecosystems. Was I able to answer your question with that or did I miss?

Might that seriously be a cormorant? It looks like one, but way up in Ohio?

Ali,

I really think this is C. fluminalis, and not C. fluminea. C. fluminalis is native to where you found this shell, and is differentiated by having 15-23 ridges per cm, whereas C. fluminea has 7-14 ridges. And C. fluminea is not known to be introduced to Iran.
