![]() The team was even more surprised to observe trails of spicules that appeared in nearly 70 percent of the seafloor images that contained living sponges. The researchers said it is not clear, given the challenging environment, how the area supports such a large community. The peaks of the ridge were found to be covered by one of the densest communities of sponges that has ever been recorded.

In some cases of sponges raised in the lab, movement involved remodeling their entire bodies.
