From Natural History of Southeast Alaska
Eelgrass (Zostera marina) occurs. This species is often mistaken for small specimens of the the related Dungeness Crab (Metacarcinus magister). The graceful rock crab does not have the sharp, toothed ridge as seen the Dungeness Crab (Metacarcinus magister). Also, in the M. magister, the posterior-most carapace spine is also the widest part of the carapace. In M. gracilis there is a tiny spine behind the spine forming the widest point of the carapace (see photo with inset).
