Green sea turtle coming ashore to feed on algae and seaweed, Turtle Bay, Oahu, Hawaii
Turtle Bay is a popular beach for the green sea turtles to come up onto the reef flat and feed. It is fascinating to see them chowing down on the sea weed. However there is a downside. Nitrogen-rich run-off from sewage and farms promotes the growth of an invasive seaweed that is reported to cause a herpes-like turtle virus to come out of dormancy. When this happens the active herpes virus causes the growth of fibropapilloma tumours on the turtles, which can be fatal.
