I was a bit bored so I thought I'd give everyone interested in the herp side of things something to do in keeping with the bird and mammal threads. Of course there's always a bit of fluctuation in what is considered a family or not but I hope I got all the currently recognized families in. If not let me know. I'd suggest marking the species seen only in captivity by underlining them; the ones seen only in the wild in bold; and those seen in both captivity and in the wild by doing both (as in the previous threads). I reckon everyone will have seen at least one species of every order, while families is gonna be a bit more difficult.^^ Order Testudines Order Rhynchocephalia Order Squamata Order Crocodilia

I'll start us off then^^ As always my memory is a bit spotty on some of the captive stuff I may or may not have seen in my time as I don't keep lists and I'm not an expert on reptiles so I don't always know if something is a new family when I go in unprepared.

So here is where I stand in terms of reptile observations as of this writing. Like the other taxonomic threads, I will be basing my list off of iNaturalist's taxon scheme, so it may differ slightly from what others have. This one wasn't as time-consuming to put together (reptile taxonomy is thankfully way less bloated than that of fish or birds). On the other hand, it wasn't as interesting either, since there is far less taxonomic diversity this time around (particularly egregious with snakes, where I have seen nearly 100 species of snakes, yet only covered 8 of the 31 families thanks to the vast majority of them being Colubrids). In total, I have observed 3 of the 4 orders of reptiles (missing Rhynchocephalia as I have yet to see a Tuatara in person) and 40 out of 92 families. Crocodilians (Order Crocodylia) - 3 out of 3 families. Rhynchocephalians (Order Rhynchocephalia) - 0 out of 1 families. Snakes and Lizards (Order Squamata) - 24 out of 74 families. Turtles and Tortoises (Order Testudine) - 13 out of 14 families Observed only in captivity. Observed only in the wild. Observed in both captivity and the wild.
