Nice find! Sounds like they live in a water environment though so I wouldn't call them desert shrimp. I was expecting to see something scampering across the dunes. I've been spelunking in some of those New Mexico caves before. I will keep my eye out for new critters next time I visit the land of enchantment. All kinds of interesting things that live down in there. Interesting, isolated environments give life to interesting new species. And they tell me evolutionary niches are a crock!
