Turtles are unique among reptiles due to their protective shells, which are made up of two parts: the carapace (the upper shell) and the plastron (the lower shell). The shell is primarily composed of bone, and the outer surface is covered with scutes, which are plates made of keratin, the same material found in human nails. These scutes provide extra protection and are arranged in specific patterns that vary by species. Over time, turtles shed and regrow scutes as part of their natural growth process. The shell itself is fused to the turtle’s skeleton, including the spine and ribs, making it an integral part of its body.nSpecifications:nnThis display features a real articulated turtle skeleton mounted on a wood basenThe photo shown is an example of what your specimen will approximately look like.
