Cryptochiton stelleri, otherwise know as the gumboot chiton due it being the size of the sole of a large boot – over a foot long.
And one wears gumboots on the beach, so that’s probably why it wasn’t called the hiking boot chiton, or the brogue chiton.
Or even the croc chiton, which would be kind of appropriate.
Except a pair of gumboot chitons worn in the mall would have more cachet than a pair of crocs.
