Thats a fake photo.
WW2 photoshopping.
lol the teeth extend beyond the front of the boat in that picture, so it ain't painted on!
................
PT196 was a south Pacific experimental boat equipped with an extended tail (fuel tank)
in an effort to create a longer range patrol boat.
Apparently the one and only WW2 USN PT Boat with a unique camouflage paint job.
