1. Plethodon
The rest from binder:
2. They have no aquatic larval stage (tadpoles), juveniles are physically similar to adults.
3. I'll go with 28. The number varies quite a bit.
4. They have no lungs - breathe through skin.
5. 18-19 (sometimes slightly more or less)
6. Caudal autotomy (tbh no idea, I just took a reasonable guess)
7. Daytime (guessing)
8. Invertebrates - insects, worms, etc.
What did you use for ID?

Seems about right. For 7 I’m fairly certain that it is disputed whether they are nocturnal or diurnal, as one study said nocturnal an another said diurnal. I made these questions without checking the answers, but from my memory, the rest seem to be correct.

There hasn't been a question in a long time so I'll ask!

1. Family?
2. Where does it eat? Give two examples of what it would eat.
3. T/F The females are polyandrous. Define polyandrous.
4. Conservation?

Okay, I got the answer without cheating, but the genus is in the URL so be careful :P
1) Emydidae
2) Can forage on land and catch prey in water; frogs and crayfish
3) F; One female gets exclusive mating rights to many males
4) Endangered

Describe the difference between viviparity, ovoviviparity, ovuliparity, and true oviparity. Give an example for each (use a reptile/amphibian if possible).

Describe the difference between viviparity, ovoviviparity, ovuliparity, and true oviparity. Give an example for each (use a reptile/amphibian if possible).
Viviparity: Live young, not eggs. Ovoviviparity: Form eggs, and the eggs stay inside the mother until ready to hatch. Can hatch either inside the body or eggs sacs are expelled from the mother’s body. Ovuliparity: (not really sure) fertilization is external. True oviparity: (not really sure either) fertilization is internal.
Viviparous: Storeria
Ovoviviparous: Nerodia
Ovuliparity: Scaohiopus
True oviparous: Elapidae

Yep, except not sure about Nerodia and Elapidae :?

¯\_(ツ)_/¯
What part of this genus's body can project up to 80% of its length?
List genus and body part.
