Along the warmth of the coast, this long, spindly-legged lizard deposits its eggs where they can fend for themselves. If a predator doesn't get them, they'll hatch into a whole new generation of yellow-bellied skinks. Up in the mountains, the eggs would have a rougher time of it. The temperature at higher altitudes drops, and the skink eggs don't have the same chance as their coastal siblings do. The yellow-bellied skink has found a solution to that; it disposes with eggs entirely and carries its young internally until it can give birth to them.

Is it a snake or a lizard!

Or...BOTH!
