How to Identify a Gumboot Chiton

The gumboot chiton is a prehistoric looking mollusk that lives in the intertidal and subtidal pools of the northern Pacific Ocean. The gumboot chiton's strange appearance and physical suggestions of ocean evolution patterns make being able to identify the creature worthwhile. Follow these steps to identify the gumboot chiton.

      Look in the right places. Gumboot chitons live in very specific areas and conditions. The chiton likes the subtidal and inter-tidal rocky pools of the cold water of the northern Pacific Ocean. To identify the chiton during the day, set out to the tide pools during foggy or overcast weather when the gumboot chiton is more likely to be out and feeding.

      Look at the animal's basic shape. The animal is difficult to identify at first sight because of its similarity to rocks and other tidal features. However, a closer look reveals a coating of various colors of algae. Touch the chiton to feel the soft fuzz of the algae to see if you can identify it as a gumboot chiton.

      Use the armored plates. One of the distinguishing features of the gumboot chiton is the armored plates that run down the back of the creature. There are eight ribs or plates (called valves) that run along a relatively soft, leathery exterior. The chiton is generally the size and shape of a football. So, use this exterior appearance to identify the chiton.

      Check the underside. The underside of the chiton resembles that of most mollusks. Running down the center of the underside is a tongue-like foot. Flanking the foot on either side are gills, which look like thin, toothed slits. At the top of the creature is a small hole, or mouth, that the gumboot chiton mollusk uses to feed on seaweeds and small creatures of the intertidal zones.
