Anguilla bicolor (McClelland, 1844) is one of the original Indonesian fish, a previous study conducted by LIPI (Lembaga Ilmu Pengetahuan Indonesia) in 2016 has found a large spawning area located in the waters of the southern coast of Java, especially in the Banten region to West Java. Anguilla bicolor’s threat status according to IUCN has increased from Least Concern to being Nearly Threatened only in the last 4 years. Anguilla bicolor is a fish that do extreme migration and can travel up to 2000 km. The ability of migration from Anguilla bicolor must be supported by good bone structure. This study aims to look at the development of Bone in Anguilla bicolor glass eel and early elver eel phase. The method that used is standart Inouye bone staining. The number of vertebrae segments in the glass eel and early elver eel was 104 segments and had been calcified. The difference between the two phases is that the cranial glass eel is still cartilage while in the early elver eel is compact bone.
