Do females or males live longer?
What is the most optimal water temperature for this organism?
T/F: Females mate every single mating season.

I'm thinking this is a musk turtle? 70%, juveniles are smaller, summer, females, 20-30 degrees Celsius, T

Nope, try again on the identification. (sorry this is a bad angle lol)

From the given angle it resembles the nominal logger head musk turtle or the flattened musk turtle. (Pictured respectively.)

But it does more closely resemble Actinemys spp.

By the way, whose turn is it?

The shell shape also doesn't quite match mud/musk turtles.

Probably better to use hide or spoiler, since people who browse the question marathons may not want to know the answer the question right away.

Ironically, this post preserves the original unspoilered version.

Anyway, axolotl, you can go if you be more specific about which features belong to alligators and which belong to crocodiles (e.g. what tooth structure do alligators have and what tooth structure do crocodiles have)

If I say that they have (for example) darker skin, then infer that the other has lighter skin
Jaw width (not counting Indian mugger): crocs have thinner
Inside jaw color: crocs are orange, gators have beige
Scute height: crocodiles have higher scutes/ridges for easier movement in water
DPRs: crocs have them everywhere, gators only have them on and around the jaw
Tooth structure: gators have conical teeth, crocs have dagger-like teeth
Tooth shape: crocs have prominent fourth tooth and same size top and bottom jaw, gators have overbite (top>bottom)
Webbing on feet: crocs have a lot more webbing
Distribution: Africa, Australia, and America have crocs, gators are only in southern US and China

I admit I had to look all of these up
1) Crocodylus porosus
2) Hylonomus, 312 mya
3) On land: the freshwater crocodile
4) Homopus signatus (Adult males are 3 inches)
5) Tropidechis carinatus
6) Komodo dragon (up to around 3 meters)
7) Olm


Anyone else can go.
