Alright guys, I just picked up a 5 to 6" Motoro today that i'm acclimating right now and i just noticed this crazy looking parasite stuck to it's back. It's about as big around as a pencil eraser, and kinda flat, but it's moving....Anyone know what this could be? Can i remove it? This is my first ray, so i'm buggin out! Any advice would be great.
