That is amazing.
OK, I'm evil. I'm wondering if it takes them nine months to develop in the egg, or if it doesn't and they're merely cued into breaking dormancy by the presence of water, like brine shrimp. Most animals with that kind of life cycle have eggs that stay dormant until they're triggered by moisture. Most of them have very short hatch times once water is available.
Wow! If someone could get colonies of those going, think of the potential there for instant feeder lizards....
