Coastal zone (lakes and marshes)

…
[Lake creatures]
Because lakes and ponds are semi-closed bodies of water, there is a very close interaction between the various organisms living there and the environment, with each lake forming an independent ecosystem as a whole. Lake ecosystems are divided into three ecological zones based on the characteristics of the habitats of the organisms in the lake and their biotic composition: the littoral zone, the offshore zone, and the bathyal zone. The littoral zone is a shallow area where large plants grow along the lake shore, and from the water's edge to the center of the lake, emergent plants, floating-leaved plants (aquatic plants with leaves that float on the water surface, such as water lilies and water chestnuts), and submerged plants are distributed in successive bands.

*Some of the terminology that refers to "coastal zone (lakes and ponds)" is listed below.

［湖の生物］
　湖沼は半閉鎖的な水塊であるため，そこに住む各種の生物と環境の間の相互作用はきわめて密接で，それぞれ湖全体が一つの独立した生態系を作り上げている。この湖沼生態系では，湖の中における生物の生活場所の特性と生物構成から，沿岸帯，沖帯，深底帯の三つの生態区分に分けられる。　沿岸帯は湖岸に沿った大型植物が生育している水深の浅い区域で，波打ちぎわから湖心に向かい抽水植物，浮葉植物(スイレン，ヒシのように葉を水面に浮かべる水草)，沈水植物が順に帯状に分布している。…
