Some of the common species of porcelain crabs in the [[Caribbean Sea]] are ''[[Petrolisthes quadratus]]'', found in large numbers under rocks in the intertidal, and the red-and-white polka-dotted ''[[Porcellana sayana]]'', which lives commensally within the shells inhabited by large [[hermit crab]]s. In [[Hong Kong]], ''[[Petrolisthes japonicus]]'' is common.<ref name="HongKong">{{cite book |author1=Brian Morton  |author2=John Edward Morton  |name-list-style=amp |year=1993 |title=The Sea Shore Ecology of Hong Kong |publisher=[[Hong Kong University Press]] |isbn=978-962-209-027-9 |chapter=Boulder shores |pages=86–125 |chapter-url=https://books.google.com/books?id=r79kKRbkzMwC&pg=PA95}}</ref>
