Thats where it gets tough, I would just hope the Test makers would make it an easy ID using a distinct species for the photo or just avoid it all together.

Okay, but then what would they test? There are approx. 25 Trachemys (sliders) species, but what would they test? I mean, how would they test this in the first place, if there isn't general information?

Also, do they often ask about specific lengths (e.g. shell usually __ to ___ mm long)?

What I did when making binder pages is to pull up info about as many species and possible and generalize it i.e. species 1 lays 10-20 eggs, species 2 lays 15-30 eggs, species 3 lays 5-10 eggs Then the genus lays 5-30 eggs. Then there would also be a section for species specific info for prominent or *special* species.

I am not sure how they would test that honestly, perhaps make it to where you have to pick out which turtle in a series of photos is not Trachemys, then ask what is the general location of this species, diet, etc. Specific info is hard to do. I see it as they can ask questions about key species just not the names.

They probably would test on stuff that is the same for all species, like size, reproduction, etc.
They might ask about specific lengths, but it can be hard because different sources give different answers.

If I were to write a question on this stuff, I would word it to be ordinal (not that that's any help in determining how the average event supervisor would ask questions).

Any tips for identifying coluber and elaphe?

I feel like coluber has a smaller and fatter head.

Anyone figure out the difference between polychridae (what's on the list) and Polychrotidae (what shows up when polychridae is googled)?

Sorry for all the questions

Unrelated, but elaphe has slightly keeled scales while coluber has smooth scales.
