coastal residents." The Latin name Cryptochiton stelleri means
Steller's hidden chiton. "Steller" is in honor of the 18th-century
German zoologist Georg Wilhelm Steller, who first described many
species of the northern Pacific seashore. "Hidden" or "concealed"

chitons are not visible, being totally internal in this genus of
