A spicule is a small, spike-like structure that can be found in various organisms, including sponges, echinoderms, and certain types of algae. They often serve a structural purpose, providing support and helping to protect the organism from predators. In sponges, spicules are made of silica or calcium carbonate and can vary significantly in shape and size. Their presence can be an important factor in the classification and identification of certain species. Spicules may also play a role in the organism's interaction with its environment.
