The fish spawn in slower-moving backwaters, typically over a substrate of cobbles or boulders. Young fish stay near shore and in quiet areas, preferring slightly more turbid water.Minckley, W.L. 1973. Fishes of Arizona.

As aggregation proceeds, the medium becomes more turbid, and its absorbance increases. The increase of the absorbance can be related to the aggregation rate constant k and the stability ratio can be estimated from such measurements. The advantage of this technique is its simplicity. Light scattering.

The adults and subadults are commonly found near the sea bottom over both high and low terrain, and sometimes among eelgrass or other vegetation. Pelagic juveniles are at shallower depths of about 120 ft. (36 m). They live alone or in small groups and are found in waters more turbid than many other rockfishes.

For example, small European perch exhibit a daily horizontal migration in some lakes in Finland. During the day they move away from the vegetated areas where the predation threat in the clear water is great, into more turbid open water areas, moving back at night because of the greater availability of zooplankton among the aquatic plants.

Almost 60 species of fish inhabit the Kura River and its tributaries. Some common families include loach, bleak, trout and nase, and many of these fish are endemic to the region. Among rivers of the Caucasus, the Kura has the largest number of endemic species. The upper section of the river supports much more biodiversity than the lower half, which is typically more turbid and polluted.

Where it overlaps with the last species, C. orinocensis prefers more slow- moving and shallow waters. They are able to tolerate more turbid waters than other species of peacock bass. It reaches up to about in standard length. Adults are easily recognized by the three large gold-edged dark spots on the side of their body (a fourth spot on the tail) and lack of dark markings on the operculum.

It has no outlet, with water leaving only by evaporation, or sub-surface seepage. The lake has about 10% of the area of the Great Salt Lake, but it has about 25% more volume. The salinity is approximately 1/6 that of sea water. Although clear Lake Tahoe forms the headwaters that drain to Pyramid Lake, the Truckee River delivers more turbid waters to Pyramid Lake after traversing the steep Sierra terrain and collecting moderately high silt-loaded surface runoff.

Amazon River near Manaus, Brazil, an example of a lowland river habitat. The generally more turbid, warm, slow- flowing waters and fine sediment beds of lowland rivers encourage fish species with broad temperature tolerances and greater tolerances to low oxygen levels, and life history and breeding strategies adapted to these and other traits of lowland rivers. These characteristics also encourage invertebrate species with broad temperature tolerances and greater tolerances to low oxygen levels and ecologies revolving around fine sediments or alternative habitats such as submerged woody debris ("snags") or submergent macrophytes ("water weed").

The population designated Ara-3 (center) is more turbid because that population evolved to use the citrate present in the growth medium. E. coli is normally unable to grow aerobically on citrate due to the inability to express a citrate transporter when oxygen is present. However, E. coli has a complete citric acid cycle, and therefore metabolizes citrate as an intermediate during aerobic growth on other substances, including glucose. Most E. coli can grow anaerobically on citrate via fermentation, if a co-substrate such as glucose is available to provide reducing power.

Fast flowing clear mountain streams flow to the valley floors of the two basins to yield a more turbid water quality, especially during periods of peak rain. This site is known worldwide as the premier habitat for the jaguar (Panthera onca), which is most often found in the vast almost unexplored West Basin wilderness. The riparian zone forest areas generally feature lush broadleaf rainforest intruding into the verges of fast flowing steep mountain streams as well as the languid meandering valley drainages. There are particularly interesting assemblages of vegetation along the rocky bedded mountain streams which have frequent rapids, waterfalls and deep pools.

A deep-sea Madreporaria collected by the Royal Indian Marine Survey ship Investigator, 1898 The taxonomy of Scleractinia is particularly challenging. Many species were described before the advent of scuba diving, with little realisation by the authors that coral species could have varying morphologies in different habitats. Collectors were mostly limited to observing corals on reef flats, and were unable to observe the changes in morphology that occurred in more turbid, deeper-water conditions. More than 2,000 nominal species were described in this era, and by the rules of nomenclature, the name given to the first described species has precedence over the rest, even when that description is poor, and the environment and even sometimes the country of the type specimen is unknown.

Seal Rocks (in distance), Phillip Island, Australia The Summerland Peninsula is approximately 360 hectares in area and is an exposed coastal plateau surrounded by coastlines of sandy and basalt boulder beaches and rock platforms among rocky basalt cliffs. Other major landforms include a coastal dune system and wetlands, made up of a freshwater lagoon, Swan Lake, and swamp, Green Lake. The north coast of the peninsula faces into the calm waters of Western Port Bay and the south coast into the more turbid waters of Bass Strait. The area includes the offshore rock formations of the Nobbies, three small islands, and Seal Rocks (Seal Rock and Black Rock) two rocky islets of 8 hectares, about 1.5 km off the western tip of the peninsula in Bass Strait.

The Neosho mucket has a marked tendency to securely anchor itself in gravel substrata with its foot. This may confer it an advantage in waters with high current speeds. For example, in Spring River it has been found to be a dominant species in fast flowing stretches; whereas it appears to be less dominant in slower and more stable habitats in other Kansas waters. Because of the foot anchoring adaptation to unstable habitats typical of the Spring River Basin, and the colourful mantle lure which would be effective in attracting host fishes in the clear waters, the Neosho mucket is hypothesised to have evolved in the Spring River or other Ozarkian streams; rather than in the western part of the range where the waters are generally slower and more turbid.
