The terrapin is a turtle-like creature that lives in fresh and brackish waters. He has a rigid beak, outstanding night vision, and a bony shell derived from his ribs. No matter how hard he tries, a terrapin can not crawl out of his shell. In addition, he can not stick out his tongue. The pattern on a terrapin’s shell is achieved by weaving colored threads in an alternating manner to form blocks of color that repeat in a series of squares and lines. The pattern and colors of a particular terrapin can be used to identify the Scottish clan to which he belongs.
