If we're using Epler...
...then I think this is Ranatra buenoi. You can see the single longitudinal depression, and according to Epler, only the buenoi have this depression of the FL Ranatra.

As v pointed out, the key in
As v pointed out, the key in Epler's Florida Bugs book will be the best source for you to identify your Ranatra specimen. If you'd like someone to attempt an ID from photos posted here, try providing these three additional shots: (1) close up of foreleg with the tibia pried away from the femur (as in the photo above); close up of the underside of the head so the antennae may be seen (the shape of the segments is important; you may have to bend the forelegs back to expose this view); and (3) a good view of the prosternum (to show whether there is one wide longitudinal depression, two narrow ones or none at all).

Thank you Brady. So far, still alive. I'll get the shots tommorrow.

Are those parasites?

 
Yep!
Probably mites because Ranatra get mites all the time! It's odd to see them without mites in my experience.
