Dermis Turtle

Dermis Turtles are small, peaceful turtle Rahi with almost impenetrable silver shells. They are good weather indicators: they would retreat into their shells if a storm was on the way. Rahaga Gaaki said they also had a musical cry that the Ga-Matoran on Metru Nui had gotten used to and even enjoyed. They can use their sharp silver tusks for defense.

Following the Battle of Bara Magna and the collapse of the Great Spirit Robot, the Dermis Turtles later left the Matoran Universe to begin new lives on Spherus Magna.

Trivia

 * The Dermis Turtle was designed for the BIONICLE: Rahi Building Contest, and was picked a winner. Greg Farshtey brought the turtle and the other contest winners into BIONICLE canon.
