Happy World Turtle Day!
The American World Tortoise Rescue began World Turtle Day in 2000 to draw attention to turtles and tortoises, to increase knowledge about and respect for them, and to encourage human action to help them survive and thrive [www.tortoise.com].
- Turtle shells have nerves and a blood supply, making them an active part of turtles’ bodies.
