Might have done more with this but was very tired. Massive lizard type creature that lives on a desert planet. Adopting a genetic idea from a type of frog that carries it's young on it's back in similar type bubbles until they are ready to be on their own this lizard does much the same thing. The sharp alternating temps on the planet make it safer for it to carry them at body temp than to bury the eggs. This lizard travels for long distances in search of water and stores it much like a camel would only in it's legs rather than on it's back.
