The first tentacle pores have no arm spine; pores have five or six arm spines from the second to 14th or 15th. The number of the arm spines decreases gradually on subsequent segments to one toward the arm tip. Throughout the arm, all arm spines are approximately half length of the corresponding arm segment, and are covered by thin integument (

D, F–H). Arm spines in the basal one-fourth of the arm are ovoid, carrying two to six terminal projections. Inner most spines have four or five terminal projections, the outer ones have two or three. In the middle one-quarter to three-quaters of the arm, arm spines are transformed into hooks; the inner most spines possess three inner teeth and the outer ones have two. On the distal quarter of the arms, the arm spines are hook-shaped and have two or three inner teeth. The hook-shaped arm spines can be distinguished from hooklets on aboral and lateral surface by having reticular structure on their basal portion.
