Non-directional photoreceptors in the pluteus of Strongylocentrotus purpuratus
Published 2016-11-01“…Here we describe the spatiotemporal expression pattern of the major molecular actors mediating light reception – opsins – localized in the Strongylocentrotus purpuratus larva. In contrast to other zooplanktonic larvae, the echinopluteus lacks photoreceptor cells with observable shading pigments involved in directional visual tasks. …”

Variation in purple sea urchin (Strongylocentrotus purpuratus) morphological traits in relation to resource availability
Published 2021-04-01“…Extensive underwater surveys of habitat attributes (e.g., sea urchin density, algae cover) were paired with detailed laboratory assays (e.g., sea urchin dissections) to determine how resource abundance affects energy allocation between reproductive capacity and body structure in the purple sea urchin, Strongylocentrotus purpuratus. We found that: (1) sea urchins had a more elongate jaw structure relative to body size in habitats void of macroalgae (i.e., barrens), (2) sea urchin reproductive capacity (i.e., gonad index) was lower in barrens and the barrens habitat was primarily comprised of encrusting algae, and (3) sea urchin jaw morphology (i.e., lantern index) and reproductive capacity (i.e., gonad index) were inversely related. …”

Effect of thermal stress on survival and delay of metamorphosis in larvae of the purple sea urchin Strongylocentrotus purpuratus
Published 2011-06-01“… The effect of thermal stress (heat shock) on survival was evaluated for advanced larval stages and the possible effect on delay of metamorphosis in competent larvae was also evaluated in the purple sea urchin Strongylocentrotus purpuratus under laboratory conditions. Eight-arm precompetent and competent larvae were kept at 15, 19, 23, 28, and 31 ºC during 24 h to estimate their thermal tolerance and measure their survival in each treatment. …”
