  • The specimens of Peregrinamor ohshimai, an ecto-commensal species to Upogebia major, were collected from the mudflat of Chilcheondo Is., Geoje-si, Gyungsangnam-do, Korea and diagnostic characters of P. ohshimai were analyzed. The genus Peregrinamor is reported in Korean fauna for the first time.

  • Complete 18S rDNA sequences were determined for 10 vetigastropods in order to investigate the phylogeny of Vetigastropoda, which is controversial. These sequences were analyzed together with published sequences for nine other vetigastropods and two nerites. With the two nerites as outgroups, the phylogeny was inferred by three analytical methods, neighbor-joining, maximum likelihood, and maximum parsimony. The 18S rDNA sequence data support the monophyly of four vetigastropod superfamilies, the Pleurotomarioidea, the Fissurelloidea, the Haliotoidea, and the Trochoidea. The present results yield the new branching order: (Pleurotomarioidea (Fissurelloidea ((Scissurelloidea, Lepetodriloidea) (Haliotoidea, Trochoidea)))) within the vetigastropod clade.

  • To investigate the phylogeny of Patellogastropoda, the complete 18S rDNA sequences of nine patellogastropod limpets Cymbula canescens (Gmelin, 1791), Helcion dunkeri (Krauss, 1848), Patella rustica Linnaeus, 1758, Cellana toreuma (Reeve, 1855), Cellana nigrolineata (Reeve, 1854), Nacella magellanica Gmelin, 1791, Nipponacmea concinna (Lischke, 1870), Niveotectura pallida (Gould, 1859), and Lottia dorsuosa Gould, 1859 were determined. These sequences were then analyzed along with the published 18S rDNA sequences of 35 gastropods, one bivalve, and one chiton species. Phylogenetic trees were constructed by maximum parsimony, maximum likelihood, and Bayesian inference. The results of our 18S rDNA sequence analysis strongly support the monophyly of Patellogastropoda and the existence of three subgroups. Of these, two subgroups, the Patelloidea and Acmaeoidea, are closely related, with branching patterns that can be summarized as [(Cymbula + Helcion) + Patella] and [(Nipponacmea + Lottia) + Niveotectura]. The remaining subgroup, Nacelloidea, emerges as basal and paraphyletic, while its genus Cellana is monophyletic. Our analysis also indicates that the Patellogastropoda have a sister relationship with the order Cocculiniformia within the Gastropoda.

  • 오징어의 actomyosin과 myosin은 3$0^{\circ}C$에서 최대 Vmax를 나타냈고 대합의 actomyosin과 myosin은 35$^{\circ}C$에서, HMM은 $25^{\circ}C$에서 최대 Vmax를 보였다. 또한 근원섬유단백질의 열 안정성은 염농도의 차이에 따라 크게 변하여 염농도가 높을수록 변성의 정도가 컸으며 대합의 근원섬유단백질이 오징어의 근원섬유단백질보다 높은 열 안정성을 나타냈다. 근원섬유단백질에 3%의 에탄올을 첨가하여 가온하면 변성은 가속화되었으며 변성속도에 있어서도 동물간에 차이가 있는 것으로 나타났다.
