| Abstract |
A specimen of Henricia was collected from the adjacent waters of Moseulpo, Jeju Island, Korea, using fishing nets. The specimen was identified as Henricia aspera Fisher, 1906, which belongs to the family Echinasteridae of the order Spinulosida. This species can be distinguished from other Henricia species by its broad arms (R/r=4.1), swollen arm base, three to seven short abactinal spines, and close-meshed formation of the actinal skeleton. This study has newly recorded H. aspera inhabiting the Korean fauna, bringing the total number of known Henricia species in Korea to 16. This study provides a description of the morphological characteristics of H. aspera with photographs of each part. Additionally, a table is presented that compares the morphological characteristics of H. aspera with closely related Henricia species. |
