Chondraster grandis (Verrill 1878) Figure 5A, D–E Chondraster grandis is a widely occurring species in the North Atlantic which occurs at moderate to abyssal depths in the western and eastern sides of the Atlantic. The genus includes only two species with the second species Chondraster elattosis known primarily from South Africa and subantarctic Indian waters. Chondraster was recently reviewed by Mah and Foltz (2014). The observation herein represents the first published account of an in situ observation for this species, although Mah and Foltz (2014) mention earlier observations by Okeanos Explorer from this region. Color of this species is highly variable and ranges from a fleshy pink (in the North Atlantic “unnamed canyon” locality, Fig. 5A) to a rich purple (on Richardson Ridge, further south) to a dark, solid red to purple color with light tan colored papulae (Fig. 5 D–E).
