Yes they have tortoise here and wild turtles in the ponds.

Back packs are allowed. I took water in with me on last visit. They are subject to search. But I think they are allowed.

Yes, an entire island of them.

The zoo is 500 acres of mainly wooded terrain. There is local wildlife there. I didn't see any wild snakes but I did surprise a raccoon that was trying to raid a trash can.

Motorized wheel chairs/scooters are $28 for the day and are first come first served. There are a few sizable hills (at least in the African side) so a motorized chair is worth the $$ if you must have someone wheel you around.

Yes. Right as you enter either gate, at the gift shop.

think well

The zoo has American alligators but no crocodiles unfortunately.

Last time I was here they made me check my baby. They have nice climate controlled cubbies

They have 2 polar bears.
