The species has been studied for its behavioral responses to environmental stressors including ocean acidification and warming.
Pachycheles rudis
thickclaw porcelain crab, big-clawed porcelain crab
Pachycheles rudis is a porcelain crab in the family Porcellanidae, commonly known as the thickclaw porcelain crab or big-clawed porcelain crab. It inhabits the East Pacific coast from Baja California to Kodiak, Alaska. The species is a filter feeder that typically occurs in heterosexual pairs and exhibits size-assortative pairing with apparent long-term mate recognition. It is frequently found in crevices, nooks, and interstices, often occupying discarded barnacle shells lined with the bryozoan Alcyonidium.
Taliepus nuttallii
southern kelp crab, globose kelp crab
Taliepus nuttallii, commonly known as the southern kelp crab or globose kelp crab, is a true crab species in the family Epialtidae. It inhabits kelp forest ecosystems along the East Pacific coastline. The species was originally described as Epialtus nuttallii by Randall in 1840 before being transferred to the genus Taliepus. As a member of the kelp crab group, it is adapted to life among macroalgae, though specific ecological details remain limited in available sources.
