Pseudoruegeria limi sp. nov. isolated from mud flats in the Yellow Sea in Korea.

A Gram-negative, aerobic, non-motile and rod-shaped bacterial strain, D-17(T), was isolated from mud flats in the Yellow Sea in Korea. Phylogenetic trees based on the 16S rRNA gene sequence showed that strain D-17(T) belongs to the genus Pseudoruegeria and it shared 97.5 % similarity with the type strain of Pseudoruegeria haliotis WM67(T).

Aestuariibaculum scopimerae sp. nov., isolated from the globular ghost crab, Scopimera globosa.

A Gram-staining-negative, non-motile, catalase- and oxidasepositive bacterium, designated strain I-15(T), was isolated from a crab of the Yellow Sea, Korea. On the basis of a 16S rRNA gene sequence analysis, strain I-15(T) was shown to belong to Bacteroidetes, related to the genus Aestuariibaculum. Sequence similarity between strain I-15(T) and the only type strain of the genus Aestuariibaculum, Aestuariibaculum suncheonense SC17(T), was 96.

First record of three species of octopodidae and gonatidae, cephalopods in the East/Japan Sea.

Three species of the unrecorded octopus and squids, Octopus megalops, Berryteuthis magister and Gonatopsis makko were collected for the first time from the East/Japan Sea in June, 2005. New Korean names proposed for these three species are "Big-eye octopus, Mako gonate squid, Schoolmater gonate squid" for the O. megalops, B.
