I was at a reptile show today in New Orleans and saw mangrove snake for sale in a deli-cup next to deli-cups filled with corn snakes, spotted pythons, and other non-venomous snakes. My question: how toxic is their venom? This show does not allow for venomous reptiles to be sold, so I guess most people don't consider them venomous enough to be of concern for the rules? I am just wondering because I always thought they were "somewhat" dangerous, but perhaps I am wrong.
