The Jack Facente Serpentarium/MToxins Venom Lab is a reptile zoo/venom lab in Oshkosh, WI. It opened only last year, on an honestly sketchy looking street corner. I am happy to say that this outside impression does reflect the actual quality of the facility, however.

Note about the name: Jack R. Facente Serpentraium and MToxins Venom Lab are the same facility, and I don't know which name is better to use. Their logo and website use MToxins, but it's listed here on ZooChat under the Setpentarium name. Both names are equally large on the front of the building. For the rest of this this review I will refer to the facility as "MToxins" simply because it is easier to type.

The entire facility is in one large room. Two walls are completely covered in terrariums, and the third wall contains windows looking into the venom lab. There are also some terrariums in the middle of the room. The terrariums at MToxins are all approximately the same size, but each is clearly customized for its inhabitants. Each is naturalistic and resembles the natural environment of the species found inside it. Apparently, each terrarium is also bioactive, meaning it contains an ecosystem of various inverts such as isopods and springtails to clean up the snake's poop and shed skin. These are some of the best reptiles displays I have ever seen, although some of them are perhaps a bit on the small side for some of the larger snakes.

The reptiles collection here is truly impressive as well. I saw 49 species of snakes on display, all venomous, including some extreme rarities. This is among the best, if not the best, collection of venomous snakes in any North American zoo.

There's a few non-reptile exhibits here, too. A small pen on the floor in the middle of the room contained a young Fennec Fox, only a few weeks old. This little guy was extremely playful and was obsessed with this cat toy with a little bell on it. The entire time I was here I could hear the ringing from the Fennec Fox playing with the toy. The other non-reptiles exhibits here included a macaw in a cage and three tethered birds of prey (two owls and a Bald Eagle).

While I was here several animal ambassadors were brought out, and I also got to see some venom extraction in the lab. Here at the Venom Lab they extract venom from various species of spider, snakes, and scorpions in order to make antivenom. I actually got to see venom extraction from three species (Cottonmouth, Spectacled Cobra, Monocled Cobra) while I was here, which is very cool. I also learned from talking with the owner that MToxins is only of only 9 venom labs in the world, one of only two that harvests venom from both vertebrates and invertebrates, and the only to harvest centipede venom. It seems a bit odd it would be located in Oshkosh, Wisconsin, which has no wild venomous animals.

Overall, I highly recommend a visit. MToxins has one of the greatest venomous snake collections in North America, probably in the world, too. It is easily one of the best zoos in Wisconsin, and probably one of the best specialist collections in the US. This is a must-see if you are in the area!

WOW. The only place I can think of to rival it in numbers might be the rattlesnake museum, which is even more specialized. Luray doesn't come close, and their exhibits are awful. Glad to hear the outside doesn't reflect their exhibits or care. Thank you for your detailed review!
 
That's an astonishing list of species. I'll have to visit the next time I swing through Wisconsin. ;)
 
I just noticed their website lists 200 snake venoms for sale - that means MToxins has >200 species of just venomous snakes (as not all on-exhibit species were listed)!

It also lists 10 scorpion species, 21 spider species, 6 centipede species (including an undescribed one)!

Having the venom for sale does not automatically mean that the species is currently kept or has ever been kept there, sonce dry venom can be bought from other sources and stored there for a while if conserved adequately.
