ALT During Dive 08 of the third Voyage to the Ridge 2022 expedition, a rarely observed aggregation of sea urchins (Conolampas sigsbei) was seen, much to the delight of scientists onboard and onshore. The urchins each appeared to have a cluster of debris on the apex of its body, leading scientists to liken them to “hats.” Image courtesy of NOAA Ocean Exploration.

ALT Monkfish: This monkfish was hard to spot camouflaged against the seafloor at 861 meters (2.825 feet) depth during a Windows to the Deep 2019 dive to explore the south-facing wall of Washington Canyon off the coast of Virginia.

ALT Crab: This decorator crab was observed using its modified back legs to carry a glass sponge on its back at a depth of 762 meters (2,500 feet) during Dive 12 of Windows to the Deep 2021. It is thought that decorator crabs use materials from their environments, such as sponges, as camouflage, to avoid detection. Image courtesy of NOAA Ocean Exploration.
