3a. Stratum corneum, Stratum germinativum, Dermis
3b. Segregates excretions so embryo doesn’t poison itself

Since no one has posted in a while I guess I’ll post


What is the average size of a specimen in this genus?
What sexual dimorphism is exhibited by members of this genus?
What is a distinguishing feature of the tails of organisms in this genus?
What is the clutch size?
How do these organisms obtain body temperatures higher than air temperature?

1. You didn't ask for ID but it's Glyptemys.
2. I'm going to say like 11cm??
3. Females have flatter plastrons, smaller tails, vent is beneath carapace edge
4. V-shaped notch at the tail
5. I'm gonna go with like 2-10 (it's hard to average these numbers between the two species, not sure what you want)
6. Orienting their shells toward the sun and staying out of the wind

1.ID down to the most specific taxon on the list
2.do they make good pets? why or why not?
3.true or false: they are more heat tolerant than other snakes
4.why are the tails of these animals sometimes heavily scarred?
5.how much of their total length does the tail usually take up?

[Fallsbury]

Lol im actually bad at herp (like really bad) but here's my guess
1) Charina
2) Yes because they are quite docile and have a low cost of maintenance
3) True?
4) The tail gradually tapers, ending in a blunt stub. This also gives the illusion of 2 heads.
5) 14%
