From my experiance, no, I've even had adult painted turtles kill baby snapping turtles, I reccomend you keep them separate
Turtles like dogs and people arent in desprate need of company but it would help prevent depresion.
Yes baby sea turtles live with their parents but they grow oder and oder their parents live them or they live their parents.
Turtles can be cannibalistic. Adult and hatchling turtles should not mix. Also turtles with large size differences should be kept separate. A larger turtle would quite happily take a snap at a hatchling causing serious damage or death. So no, don't mix your baby turtles with your adults.
not sure - i think they can
Wherever their alive
For a while, yes. Turtles can live up to three months without water. This is not to say that you shouldn't try to find it as fast as possible.
It depends what kind of turtle it is is and how big it is.
no they live in the water they're hole life
how big can a snapping turtle get? The common snapper can reach 50-80 lbs. and can live 40-50 years attaining a carapace size of 18'. That is correct!
Turtles do not give birth to live young. All baby turtles, of all species, are hatched from eggs.
No. Not unless you're prepared to take care of all the baby turtles they will have together.
ya they can but not a salamander with a snapper turtle the snapper will eat it
