As a former teacher, I couldn't resist sending this to my kids for their "Educational Moment of the Day". Whether they read it or not . . . ? I thought it was very interesting and love the nickname, Wandering Meatloaf.
This is a very common chiton in local waters, especially in Johnstone Strait and the other channels of the Inside Passage. Here, it is usually called the Gumboot Chiton, which is also a name used in Wikipedia.
My son tells me that Wandering Meatloaf opened up for The Allman Brothers on their ‘73 tour. That's one remarkable chiton!
