Snapshot of the Spotted Porcelain Crab

What has large pinchers, spotted and lives in the ocean? The Spotted Porcelain Crab!


Neopetrolisthes maculatus, commonly referred to as the Spotted Porcelain Crab or the Porcelain Anemone Crab, is a Pacific ocean crab mainly found in the Eastern hemisphere of the world. The bright unique coloration it displays is the first thing people notice when looking at this crab. Along with many other organisms, the N. maculatus varies in size depending on the living conditions. In the ideal living conditions, this organism can grow up to 3.5cm in length. For such a small organism, they have developed large pinchers located at the front of their body. The Spotted Porcelain Crab has a very unique mutualistic relationship with a sea anemone; more specifically, the Phymactis papillosa (Valdivia and Stotz, 2006). Without the sea anemone, this crab would not exist.
