You should head over to Shrimpnow.com (much nicer guys over there:icon_cool ) and look around... I've seen some pictures..Nothing too special mostly just small stuff like CRS banding on legs and things like that make them look obviouslt like hybrids. Sometimes the carapace (body/tail) gets all banded funky but you see a ton less pictures of that so I think it is probably a bit more uncommon. But then again, no one really tries to cross these two shrimp because it would screw stuff up... VERY complicated; I asked this question once..... it was too confusing so I just decided its a big NO NO!
