Clown Featherback
The clown featherback (''Chitala ornata''), also known as the clown knifefish and spotted knifefish, is a nocturnal species of tropical fish with a long, knife-like body. This Notopteridae, knifefish is native to freshwater habitats in Cambodia, China, Hong Kong, Laos, Macau, Thailand, and Vietnam, but it has also been Introduced species, introduced to regions outside its native range. It is one of the world's most invasive species.

The IUCN Red List Of Threatened Species
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 within th ...

Chitala
''Chitala'' is a genus of fish of the family Notopteridae. This genus contains six species, some of which are important in aquaculture and the aquarium industry. They are commonly known as the Asian knifefishes or featherbacks. They are native to freshwater in South East and Southeast Asia. The largest fish in the genus (and also the family) is ''Chitala lopis'', which grows up to a length of . Other well-known species are the clown knifefish (''C. ornata'') and the Indochina knifefish (''C. blanci''). Species There are six recognized species in this genus.

Coriander
Coriander (), whose leaves are known as cilantro () in the U.S. and parts of Canada, and dhania in parts of South Asia and Africa, is an annual plant, annual herb (''Coriandrum sativum'') in the family Apiaceae. Most people perceive the leaves as having a fresh, slightly citrus taste. Due to variations in the gene OR6A2, some people perceive it to have a soap-like taste, or even a pungent or rotten taste. It is native to the Mediterranean Basin. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. It is used in certain cuisines, like Mexican cuisine, Mexican, Indian cuisine, Indian and Southeast Asian cuisine, Southeast Asian. Description It is a soft plant growing to tall. The leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the flowering stems. The flowers are borne in small umbels, white or very pale pink, asymmetrical, with the petals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuisine Of Thailand
Thai cuisine (, , ) is the national cuisine of Thailand. Thai cooking places emphasis on lightly prepared dishes with aromatics and spicy heat. The Australian chef David Thompson, an expert on Thai food, observes that unlike many other cuisines, Thai cooking is "about the juggling of disparate elements to create a harmonious finish. Like a complex musical chord it's got to have a smooth surface but it doesn't matter what's happening underneath. Simplicity isn't the dictum here, at all." Traditional Thai cuisine loosely falls into four categories: ''tom'' (boiled dishes), ''yam'' (spicy salads), ''tam'' (pounded foods), and ''kaeng'' (curries). Deep-frying, stir-frying and steaming are methods introduced from Chinese cuisine. In 2011, seven Thai dishes appeared on a list of the "World's 50 Best Foods", an online poll of 35,000 people worldwide by ''CNN Travel''. Thailand had more dishes on the list than any other country: tom yum kung (4th), pad thai (5th), som tam (6th) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palaemon Paludosus
''Palaemonetes paludosus'', commonly known as ghost shrimp, glass shrimp, and eastern grass shrimp, is a species of freshwater shrimp from the southeastern United States. They can be considered a keystone species based on the services they provide to their habitat. They are also popular in the domestic aquarium business. Description ''Palaemon paludosus'' is up to long and largely transparent. By manipulating the pigment granules in its body, it can produce effective camouflage against its background. It is very similar to '' P. kadiakensis'', from which it can be distinguished by the arrangement of spines on the telson. Distribution ''Palaemon paludosus'' is common in southern states east of the Appalachian Mountains. It is also found in Louisiana, where it may not be native, and there are scattered records from further west, in Texas and California. Their distribution is due to decreased susceptibility to predation because of complexity in higher habitats in ''Polygonum'' be ...

Prey
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunistic or omnivorous and only practice predation occasionally. Most obligate carnivores are specialized for hunting. They may ha ...

Twilight
Twilight is daylight illumination produced by diffuse sky radiation when the Sun is below the horizon as sunlight from the upper atmosphere is scattered in a way that illuminates both the Earth's lower atmosphere and also the Earth's surface. Twilight also may be any period when this illumination occurs, including dawn and dusk. The lower the Sun is beneath the horizon, the dimmer the sky (other factors such as atmospheric conditions being equal). When the Sun reaches 18° below the horizon, the illumination emanating from the sky is nearly zero, and evening twilight becomes nighttime. When the Sun approaches re-emergence, reaching 18° below the horizon, nighttime becomes morning twilight. Owing to its distinctive quality, primarily the absence of shadows and the appearance of objects silhouetted against the lit sky, twilight has long been popular with photographers and painters, who often refer to it as the blue hour, after the French expression .

Ventral Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Tentacles
In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats. Examples of such tentacles are the eyestalks of various kinds of snails. Some kinds of tentacles have both sensory and manipulatory functions. A tentacle is similar to a cirrus, but a cirrus is an organ that usually lacks the tentacle's strength, size, flexibility, or sensitivity. A nautilus has cirri, but a squid has tentacles. Invertebrates Molluscs Many molluscs have tentacles of one form or another. The most familiar are those of the pulmonate land snails, which usually have two sets of tentacles on the head: when exte ...
