Graceful Crab

Brief Description

A medium-sized crab found in the intertidal and subtidal zones of the Pacific Northwest, identifiable by its smooth carapace and lack of hair on its legs.

Characteristics

Smooth, oval-shaped carapace that is widest at the 9th tooth. It typically has a purplish-brown to tan color. Unlike the Dungeness crab, its walking legs are slender and lack the characteristic hair or 'fringe' found on other species.

Habitat

Found in sandy or muddy bottoms, eelgrass beds, and occasionally rocky intertidal areas in bays and estuaries like Puget Sound.

When to Find It

Year-round; best observed during low tide when they may be trapped in tide pools or shallow water.

Conservation Status

N/A

Ecological Role

Acts as both a predator of small invertebrates and a scavenger. It serves as an important food source for larger fish, octopuses, and sea birds.

Easily Confused With

Dungeness Crab (Metacarcinus magister) - Dungeness have white-tipped claws and hairy legs; Red Rock Crab (Cancer productus) - Red Rock crabs have black-tipped claws and a much thicker, brick-red shell.

Observation Tips

Look in eelgrass beds during very low tides. Handle with care if necessary, as they can pinch, though they are generally less aggressive than Red Rock crabs.

Interesting Facts

Despite its name, it is a close relative of the commercially famous Dungeness crab, but it stays smaller and is not a primary target for commercial fishing.
