New Zealand has 43 endemic species of gecko that give birth to live young (a reptile that lays eggs is said to be gravid when she is holding eggs inside of her rather than pregnant).
New Zealand geckos are unusual in that they give birth to live young (usually twins) rather than laying eggs.
There are 43 endemic species of gecko that give birth to live young and only one other species of gecko in the world (from New Caledonia) that does this. New Zealand geckos are extremely slow breeding, most only have two offspring per year. But they are very long-lived: some are more than 45 years old!
