In Systematic Zoology Lab Practicum 2012, 30 undergraduate students in the Division of Biology, Department of Biological Sciences, School of Science, Hokkaido University went to Oshoro Marine Biological Station on 21 May, 28 May, 4 June, and 25 June 2012 to collect marine invertebrates, particularly among laminarian holdfasts and mussel beds. Clumps of the laminarian holdfasts and mussels were dissected at the marine station, and various invertebrates that crawled out from the sediments were sorted out and roughly identified. Each pair of students selected one invertebrate specimen, which was photographed in living state and fixed in 99% EtOH.
     After bringing the specimens back to the laboratory in the Sapporo campus, the students extracted DNA, amplified mitochondrial cytochrome c oxidase subunit I gene (COI), and determined the sequence. In some cases they were not able to amplify COI region; in such cases they sequenced 28S rDNA instead.
