Glass Sponge

On Dive 02 of the 2019 Southeastern U.S. Deep-sea Exploration expedition, we came across this unusual glass sponge with a fringe of large spicules at its base. It may be a new species or may expand the range of a known species (Anoxycalyx (Scolymastra) joubini), which has only been documented in the Antarctic region.
