Glass Animals

While exploring Horizon Guyot, a seamount located north of Johnston Atoll, scientists observed a seafloor community dominated by several species of hexactinellid – or glass – sponges. Glass sponges have skeletons made of silica, which is the same material used to make glass; however, glass sponges are not glass, per se.
