Rützler & Muzik, 1993 is a poriferan species that competes with corals and is known as a coral-killing sponge. However, limited information is available on its biology, including morphological traits. This study aims to examine the arrangement and development of spicules in various body parts of the sponge, including settled larvae. Spicules were found to appear on the second day after settlement and were present in all individuals on the fifth day. The spicules in the thread-like tissue of the growth portion were oriented in the direction of growth, with their pointed tips facing forward to support the elongated pioneer tissue. Furthermore, the spicules in the surface layer of the sponge tissue were perpendicular, with outward-facing tips associated with collagens. The study indicates that the spicules of are arranged to support both encrusting basal tissue and pioneering tissue to colonize corals.
吕茨勒氏海绵（Rützler & Muzik, 1993）是一种与珊瑚竞争的多孔动物物种，被称为杀珊瑚海绵。然而，关于其生物学特性，包括形态特征的信息有限。本研究旨在检查该海绵各个身体部位（包括附着的幼虫）中骨针的排列和发育情况。发现骨针在附着后第二天出现，到第五天时所有个体中都有骨针。生长部分丝状组织中的骨针沿生长方向排列，其尖端向前以支撑伸长的先锋组织。此外，海绵组织表层中的骨针是垂直的，朝外的尖端与胶原蛋白相关。该研究表明，吕茨勒氏海绵的骨针排列是为了支撑覆盖性的基部组织和先锋组织以在珊瑚上定殖。
