I went this afternoon and it was pretty hot. But not intolerable. I fished for more than an hour with one dink. Then I cast a T rigged craw to some deeper structure at the mouth of a small cove. I felt the line go limp and reeled up the slack and set the hook solidly. This fish thought it was twice the size it was. When I finally lipped it I saw its bottom jaw or lip was split or broken right in the middle. It was actually dislocated in the middle. I suspect maybe a snapping turtle. That didn't stop it from eating or fighting hard. 

Biggest smallie I ever caught had very definately once been tboned by a pike.

Well healed but noticable teeth marks/mangled scales on both flanks in that very distinctive shape.

I always wondered if that experience with a pike made that smallie more wary and ensured a longer life. They take 15-20 years to get over 5# (where I caught it)

I caught a skinny bass last year on a plastic worm.  As I was lifting it up the bass fell off of the hook, but it just lay there.  It didn't move or flop around.  When I picked it up I saw that it had a large puncture wound behind its head.  I guess a heron tried to eat it at some point.
