| 内容記述 | Herein, we report a unique morphological characteristic of Japanese sand lances, genus Ammodytes, inhabiting the northern Sanriku Coast. Japanese sand lances are distributed widely in Japanese coastal waters and possess vivid spots on the both sides of their head, which reflect environmental light and can be visually observed. However, the population in Otsuchi Bay, Iwate completely lacks these spots, which is mutual in the sympatric species A. japonicus and A. heian. This difference in the local population in the Otsuchi Bay relative to those in other localities has been likely overlooked because the spots quickly disappear after the fish dies; therefore, they are not recognizable in preserved specimens. Furthermore, the population in Sendai Bay, Miyagi consists of individuals with these spots present (75%) and absent (25%), suggesting an immigration of the latter from the northern Sanriku Coast. Microscopic observation revealed that the spots are iridophore-like cells because of their oval shape and the absence of pigments and are probably connected to the nervous system. The present study should encourage future research to clarify the taxonomy and population structure of Japanese sand lances, whose stock has been decreasing and for which a management plan is urgently needed. | |||||
