Turtles are cold-blooded reptiles, and most of them are protected by a cartilaginous shell, which is developed from their ribs.
The name "leather back turtle" comes from the turtles soft, leathery shell. Unlike most turtles, the leather back turtle has a flexible shell.
If the bottom shell is convex, it might be female. Also female turtles have the cloaca closer to the body, almost under the overlap of the shell. Male turtles have the cloaca located farther away from the body, about half the distance from the shell to the tip of the tail. Most male turtles have longer claws as well.

Most turtles do not eat snakes as most of them are vegetarians. Snakes do not eat turtles either because of their hard shell. However, snapping turtles are omnivores and will gladly eat any snake they can catch in their tough, powerful jaws.
Turtles do not really attack, the most they will do is try to snap or bite at the threat, otherwise they will usually hide from the situation by retracting the muscles and backing into their shell.

Why would you want to paint a turtle's shell anyway - unless it's for identification. A more sensible procedure would be micro-chipping ! It's permanent and doesn't wash off ! Anyway - to answer the question - so long as you use lead-free & solvent-free paint it shouldn't harm the turtle.
