Habitat

Niijima Maehama embankment

When I was swimming in the foreshore, a friend called me, "There's a strange fish!" I found three strange fish that fluttered on the surface of the water near the embankment. They were very slow swimmers and one was swept away by the waves. The large, well-developed fins were graceful.
