Sharks and a Thing

I am tired today! So here are some sharks randomly flipped to in my shark book because I am too sleepy to think of things:

Who can name what kind they are? It's not that hard, there are only four. Two are the same kind! One has teeth that probably shouldn't, and the other I'm not really sure is actually considered a shark but it might be. I have already drawn them so I am not going to look it up. I will live in misinformation forever!

And here is something I have been forgetting to scan for months!

I'm sorry.
