Glass Sponge Habitat
This picture is a preview into an entire mini-ecosystem. There’s a glass sponge (visible as the pale matrix of interwoven fibers in the background), an anemone, and a squat lobster. Glass sponges are so named because their tissue contains silica particles, the same compound that makes up glass. The sponges are filter feeders, but they do more than just sit and eat. Their intricate structures make them ideal homes for many other undersea critters.
