Fun Facts
- While all turtles sometimes get itchy and scratch their bodies or shells on hard corals or pieces of wrecks the Green Turtles of St. Maarten tend to do this a lot. Divers often find the green turtles here have less barnacle growth and cleaner shells from scratching such parasites off. Some have even developed a fondness for feeling diver’s bubbles on their stomach!
- When resting they can stay underwater for 2 to 3 hours! They don’t need to come up for air during that time because their muscles and blood store large quantities of oxygen; their heart rate also drastically slows down to conserve as much oxygen as possible
