Future porcelain crabs in trouble
Journal of Experimental Biology, 2014![Figure][1] Porcelain crabs. Photo credit: Adam Paganini. If you've ever had a fever, you'll know how rotten it feels when your temperature rises by even a few degrees. Now imagine yourself in the position of a porcelain crab on the California seashore as the tide withdraws.

Journal of Thermal Biology, 2013
Abstract Thermal tolerance limits of marine intertidal zone organisms are elevated compared to subtidal species, but are typically just slightly higher than maximal habitat temperatures. The small thermal safety margins maintained by intertidal zone organisms suggest that high thermal tolerance is associated with a physiological cost.

Abstract Settlement was studied in two vertically separated populations of the filter-feeding porcelain crabs Petrolisthes cinctipes (Randall) and Petrolisthes eriomerus Stimpson near Bamfield, British Columbia, Canada. Within their respective tidal levels, megalopae of each species settled preferentially in cages containing conspecific adults.

Biogeographic Patterns of the Galápagos Porcelain Crab Fauna
1991Twelve species of porcelain crabs are currently known from the Galapagos Islands. The basic question addressed by this chapter is: Why do these twelve species, and not any of the nearly 80 other species from the eastern Pacific, or of the more than 90 species from the Indo-West Pacific, constitute the Galapagos porcellanid fauna?

Survival and chloride ion regulation of the porcelain crab Petrolisthes armatus exposed to mercury
Marine Biology, 1974Acute toxicity bioassays conducted at various salinities demonstrated that mercury (as mercuric chloride) at low concentrations was lethal to Petrolisthes armatus. Ninety-six hour LC50 values varied from 50 to 64 parts per billion (ppb) of mercury, depending on test salinities. Lower salinities.

Mitochondrial DNA Part A, 2014
The mitochondrial genome sequence of the porcellanid crab, Petrolisthes haswelli is provided, making it the second for the family Porcellanidae and the third for the superfamily Galatheoidea. Petrolisthes haswelli has a mitogenome of 15,348 bp consisting of 13 protein-coding genes, two ribosomal subunit genes, 22 transfer RNAs and a non-coding AT-rich ...

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics, 2007
Intertidal zone organisms experience thermal stress during periods of low tide, and much work has shown that induction of heat shock proteins and ubiquitination occurs in response to this stress. However, less is known of other cellular pathways that are regulated following thermal stress in these organisms. Here, we used a functional genomics approach

Abstract Porcelain crab zoeae display vastly different morphological and swimming characteristics compared to other crab zoeae. Porcellanids have highly elongated anterior and posterior carapace spines and swim with smooth lateral directionality. While long spines have been shown to aid in predator deterrence in crab larvae, there is no empirical ...

Abstract The eyestalk of the porcelain crab houses two neurosecretory cell bodies, the Z-organs, which contain a factor controlling regeneration, molting, and oocyte maturation. The role played by the Z-organs in the regulation of these phenomena has been estimated by experimental studies.
