Coringa Wildlife Sanctuary is an estuary situated near Kakinada in Andhra Pradesh, India. It is the third largest stretch of mangrove forests in India with 24 mangrove tree species and more than 120 bird species. It is home to the critically endangered white-backed vulture and the long billed vulture. Mangroves are a group of trees and shrubs that live in the coastal intertidal zone, with a dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides; hence, the mangrove forest gets flooded at least twice per day. The roots also slow the movement of tidal waters, causing sediments to settle out of the water and build up the muddy bottom.

Achondrostoma salmantinum is a species of freshwater fish in the family Cyprinidae. It is native to five tributaries in the Duero basin in the Province of Salamanca, Spain. It is normally found in clear, seasonal streams with sandy substrates, preferring the slower flowing stretches which have an abundant vegetation of aquatic macrophytes. The species is common within its restricted range but it has a declining population and it is threatened mainly by falling water tables caused by the abstraction of water for agriculture and the construction if dams and weirs.
The Modoc sucker is a rare species of freshwater fish native to northern California and southern Oregon. It grows to a length of about 7 in (18 cm) and becomes sexually mature at 4 in (10 cm). It feeds on algae, small invertebrates and detritus, and hides under stones, detritus and overhanging vegetation. It is found in only a few streams and is listed as an endangered species in California and the United States. Conservation measures have been put in place such as fencing the streams in which it lives from livestock. It was previously rated as "endangered" by the International Union for Conservation of Nature, but this rating has now been changed to "near threatened".

Steatogenys is a genus of gymnotiform knifefishes found in the Amazon, Orinoco and Essequibo river basins in tropical South America. The widespread and common S. elegans is found in a wide range of habitats, from the shallow essentially static waters such as floodplain lakes to fast-flowing rivers as deep as 50 m (160 ft). The two remaining species are less common and widespread, with A. duidae found mainly in small streams running through terra firme forests and S. ocellatus among submerged roots and branches in static or slow-flowing blackwater habitats. All three are regularly found among vegetation in floating meadows, a habitat that often contains little oxygen, but they are well-adapted to this.
Brachygobius mekongensis is a species of goby from the subfamily Gobionellinae which is found in the Mekong basin in southern Vietnam, Thailand, Cambodia and Laos where it lives in slow flowing waters and swamps among tangled roots and vegetation. This species is infrequently recorded in the aquarium trade and is potentially threatened by degradation of its habitat by drainage, water diversion and the building of dams and bridges.
