Some asteroid specimens were collected from the subtidal zone near Gapado, Jejudo Island with fishing net on June 2010. Among them, Anseropoda petaloides (Goto, 1914) which belongs to the family Asterinidae of the order Valvatida turned out to be a new record from Korea. Morphological characters of this species collected at 130 m deep are redescribed with photographs. This species is characterized by its very thin body composed of plates imbricated into each other like scales. Twenty four asteroids are currently known from Jejudo Island, Korea.

Tunicates were collected from three harbors (Gampo, Bangeojin, Daebyeon) in Gyeongsangnam-do and one harbor (Seogwipo) in Jejudo Island during the period from August 2008 to January 2011 and were identified on the basis of their morphological characteristics. Among them, colonial tunicate Clavelina lepadiformis (Muller, 1776) belonging to the family Clavelinidae was found to be an invasive alien species introduced from the North Atlantic, and this is the first record of its occurrence in Korea.

The zoeal stages of Pisidia serratifrons are described and illustrated for the first time and its morphological characteristics are compared with those of three known Pisidia species of the family Porcellanidae. The zoea of P. serratifrons differs from those of other Pisidia (P. brasiliensis, P. dispar, and P. dehaanii), by having 11 spinules on the exopod of the antenna. In order to facilitate the study of plankton-collected material, a provisional key is provided for identification of the Korean porcellanid zoeae.

Three xanthid crabs from Chejudo island, viz., Forestia depressa (White, 1847), Pilodius nigrocrinitus Stimpson, 1858, and Palapedia integra (De Haan, 1835) are recorded as new to the Korean fauna. Up to data the Korean crabs of the family Xanthidae s. restr, consist of 15 species of 8 subfamilies.
