There are a few nudibranchs I've encountered but haven't been able to identify. Unknown #1 Unknown #2 Unknown #3 Unknown #4 Unknown #5 Unknown #6 Unknown #6 Maybe chromodoris? Close Unknown #5 Maybe glossodoris? Close Unknown #4 Likely a chromodoris or maybe nembrotha Close Unknown #3 Maybe really a flatworm? Close Unknown #2 This looks like a glossodoris or maybe chromodoris but I can't find a good match. Close Unknown #1 This might be a Pteraeolidia ianthina, but it's enough unlike the other photos of that critter that I'm not sure. Close
