The Star Turtles (Chelys galactica, also called Sky Turtles) are giant turtles living in Space. They are big enough to carry whole worlds. The most popular of the Star Turtles is Great A'Tuin. The elephants on Great A'Tuins shell are called Berilia, Tubul, Great T'Phon, and Jerakeen and are carrying Disc World. Great A'Tuins Gender is unknown, but once Great A'Tuin laid eight eggs. Some people don't think that it is a proof that Great A'Tuin is female.
The eggs of Star Turtles are as big as asteroids. If a young Star Turtle hatches it is carrying four elephants who are carrying a young world without any lifeforms.
