This article presents a comprehensive comparison of Dungeness crabs and snow crabs, examining their distinctions in various aspects. Dungeness crabs are indigenous to the western coast of North America, while snow crabs have a broader distribution in regions such as Maine, Greenland, the Sea of Okhotsk, and the Sea of Japan.

Crabs, as fascinating crustaceans, possess unique breathing mechanisms that enable them to survive both underwater and on land. With a staggering array of over 4,500 known species, these creatures primarily inhabit aquatic environments but can also be found in terrestrial habitats. Equipped with segmented bodies, protective shells, jointed limbs, and antennae, crabs draw water over specialized gills to extract oxygen underwater.
