stinkpot

aka "musk turtle"

in latin that's Sternotherus odoratus.

See the barbels under the chin.

Has a toenail-like claw at end of its tail (not pictured).

Climbs trees.

Book says "if a turtle falls into your boat while you're fishing, it's almost certainly a musk turtle."
Does that mean one is wise to wear a helmet when boating?
