porcelain crab

    • ‘In the context of physiological determinants of vertical zonation, note that many of the more coldadapted porcelain crabs could not withstand the habitat temperatures experienced by more warm-adapted congeners.’
    • ‘A group of intertidal organisms that meets many of the above criteria for selection of a study system is the porcelain crabs, genus Petrolisthes.’
    • ‘Anemone Reef consists of an anemone-covered plateau in 5 or 6m, with resident anenomefish and porcelain crabs.’
    • ‘In the vicinity there was a large clump of green sea anemones, with an adult red-studded porcelain crab perched up high.’

    • ‘Each encounter involved a single porcelain crab placed in a bucket with a single larger predatory crab, recorded by a video camera positioned on a tripod directly above the bucket.’
    • ‘Here, I summarize work on the physiological tolerance limits of rocky intertidal zone porcelain crab species of the genus Petrolisthes to emersion - related heat stress.’
    • ‘To find out how rising temperatures could affect these animals, scientists tested the thermal tolerance of porcelain crabs by hooking them up to a heart-rate monitor, immersing them in water, and gradually increasing the temperature.’
    • ‘Recent studies of porcelain crabs have revealed interspecific variation that closely mirrors the differences seen for whole animal heat tolerance.’
    • ‘On the underside of rocks lifted from the bottom cling tiny broad-clawed porcelain crabs Porcellana platycheles.’
    • ‘A purple shore crab captures a porcelain crab by firmly grasping its cheliped.’
