This sea star, likely Evoplosoma sp., was seen eating its way up a coral on a ridge at 2,006 meters (6,851 feet) depth. These large sea stars are one of the most common predators of corals that we see.

This deep-sea anglerfish, which measured 20-30 centimeters (7.8 - 11.8 inches) in length, was seen during exploration of Edmondson' seamount, at a depth of 1,260 meters (~4,135 feet). Anglerfish are ambush predators, lying motionless on the seafloor until unknowing prey swim by to be grabbed and eaten.

Ship systems and equipment were off for several weeks during the dry dock period. Part of the shakedown period includes literally turning on the power and rebooting all of the onboard computer systems to ensure the software is working and up-to-date. One computer in particular took a long time to bring online as the system had to install a lot of updates—120,641 to be exact.
