Results for “habitat”

Generally found within 15-20 km of the sea but habitat-type is extremely variable. It's been recorded in full marine conditions as well as pure freshwater environments, and commonly inhabits coastal mangrove creeks, swamps, and salt marshes. Freshwater habitats tend to comprise lowland swamps or forest streams with clear water but some populations inhabit acidic, tannin-stained, black waters. It's also abundant in the artificial canals typical of residential zones in the Gold Coast, southern Queensland.

Found in a number of habitat-types, though rarely in smaller tributaries, generally preferring deeper, flowing channels through which it travels for considerable distances at certain times of year. Like other large, migratory pimelodids these movements are typically associated with nutrient-rich, white water drainages rather than nutrient-poor black waters.

This species appears to be a relative ecological generalist. During a sampling trip in 1989 it was collected various habitat-types including a narrow (maximum width 3 m) stream containing shallow (maximum depth 1 m), transparent, moderate to fast-flowing water and substrate comprising gravel, mud, clay and organic debris including submerged logs. Aquatic plants consisted of water lilies and marginal vegetation was dense, comprising various trees, shrubs, grasses and ferns.

Nematabramis species are found a variety of habitat-types, from swiftly-flowing affluent streams to pools, lakes, and degraded swamps. Based on the available collection records juveniles and subadults of N. everetti display a preference for fast-moving water whereas adults are found in deeper, slower stretches of minor tributaries.

Apparently most abundant in shallow streams and minor tributaries, sometimes at relatively high altitudes, and apparently shows a preference for substrates of mud or silt. Given the extent of its range it would seem sensible to assume that it inhabits various habitat-types which also vary in water depth, flow, and turbidity depending on the time of year.

This species is euryhaline and mostly inhabits lowland, often coastal, habitats containing still or slow-moving brackish or freshwater. It displays a preference for habitats with surface vegetation or overhanging cover and is commonly found in mangrove swamps and rice paddies.

Endemic to southwestern Sri Lanka where it appears restricted to the so-called ‘wet zone’ (see 'Habitat'). Confirmed localities are all within the Bentota and Kelani river systems and Kottawa Forest Reserve in Galle district, Southern Province. Type locality is given simply as 'Habitat in India orientale' and this appears to have caused confusion regarding the species' distribution with it of...

Predominantly a riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, and apparently displays a preference for deeper, slower-moving stretches. In Sabah such habitats typically flow through tropical forest, although in recent years freshwater habitats throughout much of the state have been extensively modified by human activity such as conversion to palm or rubber plantations.

Inhabits ephemeral, water-filled depressions, pools and swamps mostly located in lowland floodplains. Water levels in these seasonally-variable habitats typically decrease during the dry season and eventually become completely dessicated for several months each year. Near Bagamoyo it's been collected from pools of a flat, grassy floodplain alongside the congeners N. annectens, N. janpapi and N. melanospilus, while at Soga it occus together with N. janpapi and N. ocellatus. Most habitats appear to be heavily overgrown with terrestrial vegetation.

Apparently this species is polymorphic with body patterning varying significantly depending on locality. Individuals collected from black water habitats tend to be noticeably darker in overall colouration, for example, with this being particularly evident among populations from the Guiana Shield. The genus Ageneiosus was at one point classified in...

Like most badids B. kyar is poorly documented in aquarium literature and has yet to find significant popularity in the hobby, though given its restricted natural distribution it is unlikely ever to be available in large numbers. The fish in our image is a specimen included in the only batch of this species known to have been exported to date. This species has a very slender body shape (which may be an adaptation to its habitat) and in this respect is similar to B. pyema. However B. kyar possesse...

Like most badids B. pyema is poorly documented in aquarium literature and has yet to find significant popularity in the hobby, though given its restricted natural distribution it is unlikely ever to be available in large numbers and has only been collected on three occasions to date. It has a very slender body shape, likely an adaptation to its habitat, and in this respect is similar to B. kyar. However B. kyar possesses relatively solid dark, uniform vertical bars on the flanks whereas in B. p...

Known only from a handful of localities in Bangkok, Samut Sakhon, Samut Songkhram and Samut Prakan provinces in central Thailand, all of which lie on the coast of the Gulf of Thailand. Most habitats are in close proximity to Bangkok, which continues to expand rapidly, are considered under extreme threat, and recent surveys have failed to confirm that the fish is still present in Samut Songkhram and Samut Prakan.

At one locality close to Serian, Sarawak, the habitat comprised a swiftly-flowing, clear hill stream with a substrate of quartz gravel and variably-sized rocks. The pH was 7.0 and there was no aquatic vegetation. The stream was approximately 10 metres across at its widest point and between 5-80 cm deep. B. taeniata was found in sluggish stretches among submerged tree roots, leaf litter, or overhanging riparian vegetation.

Mostly inhabits littoral to sublittoral zones, habitats which normally comprise a mixture of rocky rubble and exposed sandy areas, but has been recorded to depths of around 100 m. When not breeding adults exhibit a more-or-less pelagic lifestyle and apparently tends to form small, foraging groups in open water, whereas juveniles inhabit shallower, sandy nursery zones with some rock cover. There exists some evidence to suggest that adults move inshore at night or during early morning in order to feed.

Typically inhabits small forest streams. In the Yan Khaw Chaung (Yan Khaw stream) it occurs alongside Devario xyrops, Garra rakhinica, G. vittatula, Xenentodon cancila, Sicyopterus fasciatus and unidentified species of Lepidocephalichthys and Channa (Fang and Kullander, 2009). When sampled during the dry season the habitat consisted of nothing more than a series of small, interconnected po...

Apparently restricted to slow-moving or standing freshwater habitats such as marshes, temporal swamps and floodplains where aquatic vegetation and submerged grasses proliferate. One locality consisted of undisturbed marshland with lightly tannin-stained water and dense growth of Vallisneria spp.

C. bleheri is a popular aquarium fish though it remains unclear whether collection for the ornamentaol trade is having a detrimental effect on wild populations (see 'Habitat'). It's one of several genus members to lack pelvic fins and can be further distinguished from other Channa species by the following combination of characters: sides of lower jaw with one large cycloid scale; lateral line complete with 46-50 scales; 14 pectoral-fin rays; 25 anal-fin rays; 4-11 irregular reddish orange markings on the caudal-fin

Based on its colour pattern and limited details regarding its natural habitat this species may be adapted to dwelling between and under rocks. Alipurduar lies in the moist tropical region of floodplains and foothills of the eastern Himalayas commonly referred to as the Dooars or Duars, traditionally considered the gateway to Bhutan.

Restricted to a series of small habitats below the waterfall known as 'El Salto' in the upper Río Mezquital basin, Durango state, central Mexico. It was previously considered to occur throughout much of the upper Río Mezquital in both Durango and Coahuila states, but genetic analyses suggest otherwise and have resulted in taxonomic confusion (see 'Notes').
