An adult green mamba is roughly twice the length of a rough green snake and will have a thicker body if it has fed normally. Unless the mamba was a juvenile, it's difficult to confuse the two snakes. Let's face it - the spokeswoman for the Serpentarium would have been a LOT more convincing if she had appeared with the rough green snake in-hand when interviewed. The state needs to inspect this facility and ascertain if there is ANY chance of these non-native species escaping their enclosure. If this report is true, the Sepentarium needs to come clean and admit, "Yeah, we screwed up and this is what we're doing to make sure it never happens again." The simple fact is that if a snake can get out of its enclosure, it can certainly escape the building. We don't need a local environmental disaster. The Everglades National Park now has a thriving population of pythons and boas released by people when their "pet" got too big. Guam has seen its bird population nearly eliminated by brown tree snakes that hitched a ride in on cargo ships at the end of WW II. A Gaboon viper, native to Cenral Africa, was captured in a Chicago garage after it escaped from its owner. He had purchased it at a flea market! A few years ago, several snakes escaped from one of the many small, roadside zoos in Florida. One of them was a King Cobra, thankfully captured a short time later. It's only a matter of time before some careless collector (or careless keeper) allows a pregnant mamba or cobra to escape and we have a growing population somwhere in the Southeastern U.S. The importation of all non-native species need to be tightly regulated and controlled. If there's any truth to this story, the Sepentarium would do more good by admitting it and using it as a teaching tool, to discourage private ownership of these snakes. "If we professionals can make a mistake, so can you." (In addition to helping avert a potential eco-disaster, it might save one or two of the few dozen "collectors" who are bitten by their pet venomnous snake every year. Some bozo in Indianapolis nearly died when HIS green mamba bit him!)
