These waters include the vicinity of the mouths of the Wakayama and Kii rivers and Tomogashima Island. At the mouths of the Kii and Wakayama rivers abundant benthic organisms can be seen, with the largest populations in the Kinki region for fiddler crab, Uca lactea lactea, Macrophthalmus abbreviatus, and Gymnogobius uchidai in particular. Also numerous are Mesochaetopterus japonicus, Iravadia sakaguchii, and other rare species (Ministry of the Environment, 2001). Since it is fringed by natural rocky shores and pebble beaches, Tomogashima has a high degree of biodiversity. On its pebble beaches live Luciogobius grandis, while Callytron yuasai can be seen on its rocky shores. In the Kitan Strait, wakame and agar beds have formed (Ministry of the Environment, 2001; Wada, 2008). In recent years finless porpoises have been seen around Tomogashima as well (Hirajima, personal communication).

* This is the species list of which meet the criteria. In that matter, this list does not include all species that inhabit the individual area.
Abbreviation in the information is as follows.
[Br/Ne] : Adjacent water of breeding area or nesting site
[Sp] : spawning area
[Ad] : species not used for analysis but add to the list because inhabit information was collected later
[Ex] : species used for analysis but considered to be possibly extinct in the EBSA region (area)
No mark : data of species distribution
