Estuarine definition is - of, relating to, or formed in an estuary. The Niger Delta is a fan-shaped sedimentary environment located between the Benin River in the west and the Imo River in the east (longitudes 5o4′00″E and 7o 40′00″E), extending a few kilometres south of the village of Aboh at the point where the Niger bifurcates into several rivers with estuaries opening into the Gulf of Guinea.

Results of a year long study of the distribution of birds across five intertidal estuarine habitats reveal that tide level largely controls use of the habitats by birds. Sampling was conducted at high tide during summer in a highly turbid system, the Gironde estuary, for which primary production and thus food resource at the basis of the food web is strongly limited. A bar-built estuary, a drowned river valley and two river delta estuaries were compared and contrasted to elucidate the impact of some abiotic factors, notably climate, salinity, and oxygen on the distribution of the aquatic fauna and flora. 35: 235–250.

Estuarine Habitats and some characteristics Estuarine habitat, is a body of water formed at the coast as a result of the action of tides which mix salt water from the sea with fresh water from the land. Forty-eight species of bony fishes were recorded in Lagos Lagoon, the Escravos, and Qua Ibo estuaries and classified by salinity tolerance into stenohaline and euryhaline marine species (66%), and freshwater species (34%). This brackish water environment supports a variety of fish habitats, including: These environments provide important feeding, spawning and nursery sites for many aquatic animals.
