The disease, known as fibropapillomatosis, is thought to be caused by a herpes virus and is specific to sea turtles. Despite looking harmful, the tumors that develop on the surface are mainly benign, but problems arise when they grow over the turtles' eyes, which prevents them from seeing and therefore feeding. Around 20 years ago, vets at the Turtle Hospital in the Florida Keys were seeing around eight turtles a month with the tumors, but recently they have seen a massive increase, now seeing around eight a week.
