The fish that Mark shows is the standard pufferfish. We often catch them in Tampa Bay. The one I showed above is slightly larger with 1" long spines -- a striped burrfish. Their spines are rigid, but not sharp or poisonous, I was able to handle the fish without any issues. My guide, Neil Taylor, caught one of them today.
