Flat Porcelain Crab
Despite its name and appearance, the Flat Porcelain Crab is not a crab at all. In fact, it is more closely related to the lobster, but through a process known as carcinisation has evolved to look like a crab. The chief difference is in the number of legs - Porcelain Crabs only have six walking legs while real crabs have eight. Why some marine creatures develop crab-like characteristics is still not completely understood by scientists, but it may an adaptation to living around and under rocks where the crab’s body shape and structure is uniquely suited. The animals unique name stems from the smooth texture and subtle colors of the carapace, which, when wet, often glistens like porcelain. These false-crabs can range in color from dark brown to sky blue. At the Aquarium, look for them in the touch pool in the Rocky Shores gallery.
Range & Habitat
Porcelain crabs are found in almost every ocean on Earth. Along the West Coast, they can be found from British Columbia to Santa Barbara, California. They are very common along the Oregon coast where the rocky environment makes a perfect habitat for them. Often they can be seen scurrying quickly over the sand or into the surf on the state’s various beaches.
