Educational layout featuring Liam's encounter with the Box Turtle at the park.

The upper shell of the turtle is called the carapace. The lower shell that encases the belly is called the plastron. The carapace and plastron are joined together on the turtle's sides by bony structures called bridges. The inner layer of a turtle's shell is made up of about 60 bones that includes portions of the backbone and the ribs, meaning the turtle cannot crawl out of its shell. In most turtles, the outer layer of the shell is covered by horny scales called scutes that are part of its outer skin, or epidermis. Scutes are made up of a fibrous protein called keratin that also makes up the scales of other reptiles. These scutes overlap the seams between the shell bones and add strength to the shell. Some turtles do not have horny scutes. For example, the leatherback sea turtle and the soft-shelled turtles have shells covered with leathery skin instead.Lizzie page set, by Roberta D’Achille, Rendered Memorieshttp://renderedmemories.com/shop/index.php?main_page=product_info&products_id=173Quick Clik layered sketch by Alma Townsend, TheScrapHabitInked edge overlay and stamped alpha from Robyn England’s War kit
