Holy crud, you have got to be kidding. This animal's got its head covered in growths. Some of them are in even in in its mouth. When you see fish or other vertebrates with conditions this severe-looking, they are routinely put down. You would normally only leave something this nasty alone if you're deliberately monitoring the condition (to the detriment of the animal).
Heck, I just showed these pics to two other biologists, and all three of us horrified.
In any event, if it's a genetically-derived neoplasm, the last thing you want is that specimen releasing gametes. If they fertilize with another moray's, that's just spreading the ailment.
