red porcelain crab Petrolisthes sp.* Family Porcellanidae updated Jan 09 Where seen? This colourful flat crab with large flat pincers is often seen on some of our rocky shores, hidden under stones. After having a look under a stone, be sure to replace the stone the way you found it. Do it carefully so you don't crush any living things. Features: It's much larger than most porcelain crabs found under stones. Body width about 1cm. Body not hairy and is reddish or maroon with fine stripes. The pincers have serrated edges. Antennae much longer than the body. |
