Laetmaster spectabilis
Laetmaster spectabilis. We saw this species of deep-sea sun star in Puerto Rican waters during the 2015 Océano Profundo expedition at a whopping 3,915 meters (2.4 miles). The last time this species was seen was when it was first collected via trawl net in 1878 by the oceanographic research vessel USS Blake. It basically gave the 20th Century a hard pass!
