Betta Imbellis
The peaceful betta or crescent betta (''Betta imbellis'') is a species of gourami native to Southeast Asia. ''Betta imbellis'' has a pair of suprabranchial chambers that each house a labyrinth organ, a complex bony structure lined with thin, highly vascularised respiratory epithelium. The labyrinth organ is a morpho‐physiological adaptation that allows the ''B. imbellis'' to extract oxygen from air. This adaptation allows the species to persist in extreme conditions. Males of the species may fight each other especially when in breeding condition. Description ''Betta imbellis'' grows to a maximum standard length of . Distribution ''Betta imbellis'' occurs naturally in Southern Thailand, Malaysia, and Indonesia, although it has been introduced to Singapore. Habitat ''Betta imbellis'' lives in sluggish bodies of water, including rice paddies, swamps, streams and ponds, with a substrate composed of leaf litter and mud. Conservation status ''Betta imbellis'' is listed as leas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Ladiges
Werner Ladiges (August 15, 1910- November 13, 1984) was a German zoologist. Life He studied zoology in Innsbruck and Hamburg, where he received his doctorate in 1934. In the same year, his book ''Tropische Fische'' was published in the field of aquaristics, as well as numerous articles in relevant specialist journals. His main activity was as a scientific ichthyologist at the Hamburg Zoological Museum. Ladiges managed to make a name for himself with his influential specialist book ''Der Fisch in der Landschaft''. He is also known to aquarists for the Celebes rainbowfish (''Telmatherina ladigesi'', now ''Marosatherina ladigesi''), which he discovered in 1935 and which was named after him, and for the peaceful betta ''Betta imbellis'', which he described in 1975. For several years, Ladiges was editor of the popular aquaristic magazine ''TI – Tatsachen und Informationen aus der Aquaristik'', which was published by the accessories manufacturer Tetra in Melle, Germany.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Fish Of Thailand
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Freshwater Fish Of Malaysia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the Water resources, water resource ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betta
''Betta'' is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (biology), family (Osphronemidae). The best known ''Betta'' species is ''B. splendens,'' commonly known as the Siamese fighting fish and often kept as an aquarium pet. Characteristics All ''Betta'' species are small fishes, but they vary considerably in size, ranging from under 2.5 cm (1 in) total length in ''B. chanoides'' to 14 cm (5.5 in) in the Akar betta (''B. akarensis''). Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth organ, labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as Paddy field, rice paddies, slow-moving Stream, streams, drainage ditches, and large Puddle, puddles. The bettas exhibit two kinds of spawning behaviour: some build bubble nests, such as ''B. splendens'', while others are mouthbrood ...

Glycera (annelid)
The genus ''Glycera'' is a group of Polychaete, polychaetes (bristle worms) commonly known as bloodworms. They are typically found on the bottom of shallow marine waters, and some species (e.g. common bloodworms) can grow up to in length. Although both are visually-similar and commonly-used as fishing bait, bloodworms are biologically-distinct from lugworms. Anatomy Bloodworms have a creamy pink color, as their pale skin allows their red body fluids that contain haemoglobin to show through. This is the origin of the name "bloodworm". At the 'head', bloodworms have four small antennae and small fleshy projections called parapodium, parapodia running down their bodies. Bloodworms can grow up to in length. Bloodworms are carnivorous. They feed by extending a large proboscis that bears four hollow jaws. The jaws are connected to glands that supply venom which they use to kill their prey, and their bite is painful even to a human. They are preyed on by other worms, bottom-feedi ...

Artemia
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp or '' sea monkeys''. It is the only genus in the family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide, typically in inland saltwater lakes, but occasionally in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans ...

Daphnia
''Daphnia'' is a genus of small planktonic crustaceans, in length. ''Daphnia'' are members of the Order (biology), order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their Saltation (gait), saltatory swimming style resembles the movements of fleas. ''Daphnia'' spp. live in various aquatic environments ranging from acidic swamps to Fresh water, freshwater lakes and ponds. The two most commonly found species of ''Daphnia'' are ''Daphnia pulex, D. pulex'' (small and most common) and ''Daphnia magna, D. magna'' (large). They are often associated with a related genus in the order Cladocera: ''Moina'', which is in the Moinidae group instead of the Daphniidae, and is much smaller than ''D. pulex'' (roughly half the maximum length). Appearance and characteristics The body of a ''Daphnia'' species is usually long, and is divided into Segmentation (biology), segments, although this division is not visible. The hea ...

Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordata, chordate subphylum Vertebrata, i.e. vertebrates. Well-known Phylum, phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxon, taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 Micrometre, μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
