During Dive 03 of the 2021 North Atlantic Stepping Stones expedition, we saw several very large glass trumpet-shaped sponges, some that were well over a meter (three feet) in height. In this image, remotely operated vehicle Deep Discoverer images one of the sponges; for reference, Deep Discoverer is 2.7 meters (9 feet) tall! Watch a video of one of these sponges.
