This pycnogonid, or sea spider, was seen at a depth of 1,400 meters (4,593 feet) during a dive within Hudson Canyon, off the coasts of New York and New Jersey, as part of the 2021 ROV Shakedown. Despite their common name, pycnogonids are not “true” spiders. They are known as pycnogonids because they belong to the class Pycnogonida within the phylum Arthropoda. The look-alike land-dwelling spiders after which they get their common name are also arthropods, but they belong to the class Arachnida.
