![]() ![]() Many hexactinellid sponges have evolved elaborate networks of hair-like skeletal elements (indicated by arrows) that form the basis of an anchoring system that secures the sponges in soft sediments of the sea floor. Known as glass sponges, over the years their skeletal systems and their constituent elements (called spicules) have served as useful model systems for the design and fabrication of robust and damage tolerant structures. One such group is the hexactinellids, a collection of predominantly deep-sea sponges that produce elaborate skeletal systems of glass. ![]() Creatures of the ocean’s depths are some of the most mysterious and fascinating subjects for study, due to the challenges of collecting them from very deep waters and for their unique adaptations for colonizing the sea floor. Scientists often look to biology for inspiration and innovation, emulating the way that nature builds to advance human engineering. ![]()
