Results for “pelagic”

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.

Also known as the green lepturus, this is a stunning species when mature. Unfortunately, it is rarely seen for sale. Its pelagic nature means it is difficult to catch for export. As a result it can be quite expensive when it is available....

This species is only occasionally offered for sale, as it is difficult to collect, living a predominantly solitary lifestyle. As a result, it is much sought after by enthusiasts. It may be confused with the other species in the genus, C. caerulus, but can be distinguished by its deeper body shape and very distinctive black markings on its snout. Champsochromis have widely spaced teeth compared to some other pelagic predatory cichlids found in Lake Malawi, such as Buccochromis species....

Together with the recently erected genus Mchenga, Copadichromis species form an exclusive group of Malawian cichlids commonly referred to as "Utaka" (prounounced "ooh-taw-kuh"). They're specialised to a pelagic lifestyle, and can be found living in huge numbers throughout much of Lake Malawi. Some tend to remain in the proximity of underwater reefs or rocky shorelines, while others occur mainly in more featureless, sandy habitats. Here they face the oncoming current, us...

C. guapore is a sought after aquarium fish although it is not often traded. It exhibits slightly different behaviour to the majority of congeners in that it tends to form aggregations in midwater and spends a large proportion of its time away from the substrate. Its morphology exhibits corresponding adaptations towards a pelagic existence with a relatively large eye, a more terminal mouth position, more strongly-forked caudal-fin, and more symmetrical body shape than most other Corydoras species.

Known only from Kanyakumari District, Tamil Nadu state, at the southern tip of the Indian peninsula. Type locality is the Kodayar River drainage and it's also been collected in the Paralayar and Pamburivaikal river systems. No precise data is available but it's certainly a pelagic, riverine species with habitats likely to vary depending on locality and time o...

This species is also known by the vernacular 'jungle perch' or 'sidebar barb' and should not be considered an aquarium subject in all but the most extreme circumstances since it can grow to over 2 feet in length, weigh in excess of 5 kg and is a powerful, pelagic predator. It's also a popular sport fish with a reputation for striking hard.

The genus Mchenga was erected in 2006 by Stauffer and Konings and currently numbers half a dozen species, all of which are previous members of Copadichromis. The reclassification was based on various morphological and behavioural traits, including habitat preference and breeding strategy. Together with Copadichromis, Mchenga spp. form an exclusive group of Malawian cichlids commonly referred to as "Utaka" (prounounced "ooh-taw-kuh"). They're specialised to a pelagic l...

Some wild populations have evolved a complex amphidromous breeding strategy in which adults live and spawn in freshwater or brackish streams and the pelagic post-hatch larvae are washed downstream to the sea where the post-larval fry spend the first part of their life developing in estuarine nursery zones under brackish to full marine conditions. Once they reach a certain stage of development they begin to migrate upstream with some mov...
