caprella การใช้

• It closely resembles " Caprella septentrionalis " with which it shares the same geographical distribution.
• It closely resembles " Caprella mutica " but can be distinguished by its smooth first and second pereonites, as well as its linear-shaped gills.
• Some specimens collected from the Firth of Clyde, Scotland in 1999 were also initially misidentified as " Caprella tuberculata ", but have since been determined to be introduced " C . mutica ".
• "C . mutica " are known as " koshitoge-warekara " ( " spine-waist skeleton shrimp " ) in Japanese . " Caprella acanthogaster humboldtiensis ", another invalid name of the species, was first applied to misidentified specimens of " C . mutica " recovered from Humboldt Bay, California by Donald M . Martin in 1977.
• It may be difficult to distinguish the two species, particularly since " Caprella mutica " can exhibit considerable morphological variations among males . " C . mutica " can only be reliably differentiated by their setose first and second pereonites ( smooth in " C . acanthogaster " ), as well as the elongated oval shape of their gills ( linear in " C . acanthogaster " ).
• For example, in California, " Macrocystis pyrifera " forests, the nudibranch " Melibe leonina ", and skeleton shrimp " Caprella californica " are closely associated with surface canopies; the kelp perch " Brachyistius frenatus ", rockfish " Sebastes " spp ., and many other fishes are found within the stipitate understory; brittle stars and turban snails " Tegula " spp . are closely associated with the kelp holdfast, while various herbivores, such as sea urchins and abalone, live under the prostrate canopy; many seastars, hydroids, and benthic fishes live among the benthic assemblages; solitary corals, various gastropods, and echinoderms live over the encrusting coralline algae.
