  • A sea star was collected with fishing nets at a depth of approximately 100-160 m in the East Sea and was identified as Stephanasterias albula (Stimpson, 1853) belonging to the family Asteriidae of the order Forcipulatida. This species characterized by having the capability of asexual reproduction by self-division turned out to be new to the Korean fauna. Its morphological characteristics are redescribed with illustrations. Thirty one species of sea stars including S. albula are now recorded from the East Sea of Korea.

  • Since November, 2006, the new creeping platyctenid ctenophore, Coeloplana anthostella n. sp., has been collected from twigs and polyp masses of encrusting dendronephthyans at a depth of 26-32 m off the coast of Munseom, Jejudo Island. This new species is distinguished from C. bocki Komai, 1920 and C. komai Utinomi, 1963 by its smaller size, the absence of dorsal papillae, and the deep scarlet colored star-shaped markings on the dorsal plane. This novel addition to ctenophore fauna is presently described and illustrated in detail.

  • A new marine sponge Cinachyrella unjinensis n. sp. has been collected from Jejudo Island in 2009. This new species is similar to C. kuekenthali (Uliczka, 1929) in the shape and composition of the spicules except for style. However, it differs from the latter by size of anatriaenes, protriaenes and microxeas.

Narrabeena nigra n. sp. is similar to Narrabeena lamellate (Bergquist, 1980) with uncored primary and secondary fibres and an unarmoured surface. They differ in growth form, colour, and fibres.

  • The Korean state evolved as a distinct entity in a region of major power convergence and conflict. All states, as human constructions, seek sovereignty and life security of their subjects/citizens, and are rotted in organic society. In the Republic of Korea, constitutional order has provided a framework for political action and a succession of regimes - authoritarianism, military dictatorship, and constitutional democracy. Since 1960 two paradigms have undergone a cycle of growth and decline, and a third, since the 2016 candlelight demonstrations in Gwanghwamun, may be the beginnning of a third generation paradigm - populist constitutionalism.

  • Seventeen caprellid species are reported from adjacent waters, of the Goheung Peninsula, Jeollanam-do in June, 2008. Among them Paracaprella crassa Mayer, 1903 is newly added to the Korean fauna. We described this species with illustrations and mentioned some differences from the original description and subsequent redescriptions. As a result, Korean caprellid fauna consists of 34 species in 6 genera.
