A study finds that the heavily-loaded rostral bones of billfishes, such as marlins and swordfish, are maintained by remodeling despite lacking osteocyte cells, which are abundant in the bones of mammals and were previously considered essential for detecting and repairing bone damage. A basic tenet of bone biology states that bone strength is maintained by remodeling, in which osteocytes detect and orchestrate the repair of micro-damage caused by repeated loading.
