Loki's Lined Chiton (Tonicella lokii)

Description:

One of the prettiest of the chitons, in my opinion. You have to search for this one but if you look in the right places, you will enjoy the colors seen. Your camera will pick up on the colors more than seeing it in person. It feeds primarily on pink coralline algae. Its main enemies are the purple sea star (Pisaster ochraceus). The color is known to be modified by diet as they are pinker when eating corraline algae and greenish when feasting on diatoms.
