"The Common Barnacle, <em>Lepas anatifera</em>, perhaps the best-known example of the order, generally selects floating objects for this purpose, and frequently covers the bottoms of ships to such an extent as to even impede their progress through the water. It adheres by a flexible stalk, which possesses great contractile power. The shell is usually composed of two triangular pieces on each side, and is closed by another elongated piece on the back." &mdash; Goodrich, 1859

The Dungeness crab is a species of crab that inhabits eelgrass beds and water bottoms from the Aleutian Islands in Alaska to Santa Cruz, California. Its binomial name, Cancer magister, simply means "master crab" in Latin. They measure as much as 25 cm (10 inches) in some areas off the coast of Washington, but typically are under 20 cm (8 inches). They are a popular delicacy, and are the most commercially important crab in the Pacific Northwest, as well as the western states generally.

Maja squinado (the European spider crab, spiny spider crab or spinous spider crab) is a species of migratory crab found in the north-east Atlantic and the Mediterranean Sea. It feeds on a great variety of organisms, with seaweeds and molluscs dominating in winter, and echinoderms such as sea urchins and sea cucumbers in summer. Females can produce up to 4 broods per year. Migrations generally take place in autumn, with some crabs covering over 100 miles (160 km) in eight months.
