 note = {text, We provide information on the development of scales of cycloid type and of the squamation pattern in the medaka. During the growth period from larva to juvenile, scales begin to form concurrently with the pronounced degeneration or resorption of the median fin fold in the region of the caudal peduncle. The position of scales to be formed first may be predestined on the body surface along the horizontal septum. In medaka, the body size at which the scales first appear is 8–10 mm total length (TL). The squamation begins on the horizontal septum of the posterior region of the trunk and the anterior region of the tail and subsequently extends to the cranial, the caudal and dorso-ventral sides. Scales on the skin of the prefrontal and dorsal surface of the pectoral fin appear last. During squamation formation, the diameter and circular number of a scale gradually increases, but the number of scale rows and circuli (ridges) varies greatly among individuals. The distribution of scales closely corresponds with the somites and vertebrae.},
