A few zoos have reptile shows. What reptile species and natural behaviours could be included in a good reptile show?
For me, the most iconic reptile show and where it is located is in Australia Zoo where saltwater crocodiles are shown for performances in the Crocoseum.
Lots of zoo in Asia such as China and Thailand will have crocodile show and will put their head in the crocodile.
I think it depends on your audience and the local conditions. Imo, a good reptile show should include an introduction of native reptile species (including, if necessary, the differentiation between venomous and nonvenomous species), information regarding updated husbandry requirements of reptiles, the issue of invasive reptile species as well as reptile conservation. The actual show aspect could include medical training of various reptile species (especially larger ones) and the close inspection and monitored interaction with certain "tame" relatively harmless specimens. For the sake of the animals and the staff, I'd refrain from all too risky behaviour such as mentioned above...
