There are a few threads in the photo lounge with pics from the weekend.
As for the other stuff, like was posted... really what we learned is that 99% of the rays out there need to be reorganized in better taxonomic form so we really know what is there. Things like 6 different color patterns for an orbig can be confusing.
Threads like "ID this ray" are going to be a hot topic. If pups change patterns as much as is thought in 'hybrids' or they take after the female, you could have what looks like a nice motoro, but really it's a mix. You'd really have to have known parents to ID a captive ray anymore. Shoot, even what I "KNEW" I had for a collection of animasl is now questionable. Other "professionals" found out the same stuff that weekend.
We got a good wake up call to how much is really unknown... but knowing you don't it all is a good first step. The event was open to all ray owners for just that reason. I'll tell you I've drawn a lot of knowledge from guys and gals who keep rays as a hobby and translated it into major displays. I also hope that the info passed out from zoos/aquariums have helped the hobby.
