“It always happens around mid-summer, my team would begin to notice strange scars on the bodies of sperm whales we had documented, but these weren't your ordinary squid bites. It was then during a night dive when I had the shock of my life, swimming past me from the deep was the pod returning from their night hunt. I only saw the man-sized parasites for a few seconds, but I'm convinced I've found my culprit.”
