Notes
Similar to Serpula columbiana, this tubeworm can be distinguished by how very wide the attachment base of the tube is when compared to others. In Serpula the cemented base (imagine gluing a tube to a flat surface, first you place a line of glue. When tube is pressed down, the amount of glue squeezed outward is analogous to width of cemented base) is just about the diameter of tube. In Crucigera the calcareous base is much wider than diameter of tube. Photo taken with Pentax Optio W10 underwater
