Nice little mutation that popped up about a year ago in my iriomotensis colony, at third generation now which to me means it’s truly isolated. I know the sp name changes a lot but I am sticking with what I got them as for now to avoid more confusion.
If I had to assign this a “mutation” it’s a bit hard cause we have various forms of Lucy and albino in isopods. To me this leans more towards a T+ albino. Will see as time progresses!
Here is a photo of what a standard irmo looks like.
