A leathery shell is a shell that is flexible rather than solid like the shell of a bird egg. A snake's egg has a shell that is flexible, as does a turtle's egg.
It prevents water loss
no,some either lay eggs or give birth to live young
A marine or semi-aquatic environment would be best.
I'm pretty sure it's reptiles in general snakes, turtles.

Bivalve mollusks like clams hold their shells closed with their muscular bodies. They also have leathery "hinges" at the rounded part of the shell which help to hold the two halves together. These are similar to ligaments in higher animals. If you ever get a clam in the supermarket that is already open, that one is dead and you should not eat it.

The leathery shell of a reptile egg is to simply protect the eggs from any predators.
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.

Armadillos are small mammal with a thick leathery armour shell.
No snake does unless scientist fond another specie is found .
Monotremes are egg-laying mammals, and their eggs are not hard-shelled, but leathery. The monotremes include the platypus and echidna.Reptiles also lay rubbery/leathery eggs.
The name "leather back turtle" comes from the turtles soft, leathery shell. Unlike most turtles, the leather back turtle has a flexible shell.
Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
Mammals don't lay eggs. The only mammal that lays eggs is a platypus, and they have leathery feeling eggs, but still a shell.
