If there's one thing that unites a lot of the creatures that live in vernal pools, it's their extreme lifestyle.

They have a very distinctive strategy.

A few months ago, a wildlife biologist named Chuck Black took me out to see some

vernal pools at a marine base outside San Diego.

Vernal pools are these temporary little ponds that form when it rains, and they turn

into these little oasis that are home to a whole bunch of different creatures,

most iconic of which is the fairy shrimp.

They don't have any spines or defensive mechanisms.

They're kind of like lunch for anything that comes along,

beetles or birds or anything.

But they're very fast to reproduce. And so the shrimp strategy is to start fast, get your reproduction done, and then...

It kind of reminds me of those just add water toys as a kid, if you remember those.

It's like the rain comes, it fills up these pools, and it sort of activates the fairy shrimp eggs that have been sitting there for who knows how long.

The fairy shrimp then grow as fast as they can, they reproduce, they put out their own eggs, and then those eggs just sit there for a while, enduring droughts or fire until the next time it rains.

And that could be decades.

Or even a hundred years from now. So it's sort of like a live fast, die young. Yes, exactly.
