World Turtle Day 2018: Celebrate Turtles, Tortoises with These Facts

All around the world Wednesday, people were "shellebrating" World Turtle Day. The holiday, which falls on May 23 each year, is sponsored by the American Tortoise Rescue (ATR), an organization dedicated to rehabilitating and rescuing the creatures.

The nonprofit was established to help protect all types of tortoises and turtles, and this day in particular was created to help people learn more about the animals and how to conserve them. The ATR has guidelines available online for their treatment, which include instructions about what to do if a person encounters a turtle in a roadway, how to advocate for the fair treatment of the animals and more.

World Turtle Day is a good time for anyone looking to help protect the animals and learn a few interesting facts about them. It shouldn't, however, be confused with World Sea Turtle Day, which is celebrated June 16.
