Djakonov, 1950

The species was first described by Alexander Michailovitsch Djakonov in 1950,[1][2][3] with the holotype collected in 1925 in the Peter the Great Gulf of the Sea of Japan near the Basargin Lighthouse, at a depth of 20m in the waters off Primorsky Krai.[4][5]

It has also been recovered in Chemulpo Bay, in northwestern South Korea.[1]

It has been found on silty sand or pebble substrates.[4] It has been found at depths of 1-32m.[1]

Description

This starfish has five arms. The arms grow to 14.6cm, the ratio between the length of the arm and the radius of its disc is 4:1.[1] It has planktonic larvae.[2] Djakonov found it to be the most similar to Asterias rollestoni.[1]
