These waters include the Harioseto Strait and the Haikiseto Strait connecting Omura Bay with the open sea at the north end of the bay. Since Omura Bay connects to the open sea only through these two narrow straits, the tide flows very fast in this area. The Haikiseto Strait is home to numerous rare shellfish that inhabit tidal mud flats, and saltwater marshlands' Juncaginaceae and Aster tripolium grow here as well. It also is a habitat for fiddler crab. Snipe and plover visit here as well, although in small numbers. Rare shellfish such as Platyvindex sp., Cassidula plecotrematoides and others inhabit Egamiura in the town of Egami, in large numbers. Also numerous here are Protopterus dolloi as well as Hibiscus hamabo and other saltwater marshland plants (Sasebo city, 2013).
