While on vacation in the Outer Banks in North Carolina, my son and I put a GoPro in a crab trap so that we could take a look at all of the fish that we weren’t catching. What showed up on the video was pretty interesting. No fish or crabs were harmed in the filming of this video. The puffer fish in the video DID NOT DIE. Puffer fish inflate themselves with air when they feel threatened to avoid being eaten. As soon as they release the air they can swim normally.
