All Puffed Up
by Tim Grollimund
Puffers are a group of fish I like to shoot, especially the big ones. They have a shy, jovial personality. At least they always look like they are smiling. Puffers are related to boxfish, and are also toxic, but in a different way. I found references to two toxins, tetrodotoxin (TTX) and saxitoxin (STX), which are nerve agents. They are chemically distinct, but act on the nervous system similarly.
