Abstract

Henricia specimens were collected using fishing nets from 14 November 2012 to 8 June 2018 from the East Sea of Korea. The specimens were identified as Henricia sanguinolenta (O.F. $M{\ddot{u}}ller$, 1776), belonging to the family Echinasteridae of the order Spinulosida, which is known for its wide distribution throughout the world. This species can be distinguished from other Henricia species by long arms (R/r=6-6.8), thick arm base, coarser stubby abactinal spines with more than ten apical points, and visible longitudinal series of actinal ossicles. Previously, eight species of the genus Henricia were reported in the Korean fauna. The morphological characteristics of this species were prepared and described with illustrations.
