Moray Eel
Moray eels, or Muraenidae (), are a family (biology), family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively Marine (ocean), marine, but several species are regularly seen in brackish water, and a few are found in fresh water. The English name, ''moray'', dates back to the early 17th century, and is believed to be a derivative from Portuguese language, Portuguese , which itself derives from Latin , in turn from Greek language, Greek , ; these are the Latin and Greek names of the Mediterranean moray. Anatomy The dorsal fin extends from just behind the head along the back and joins seamlessly with the caudal fin, caudal and anal fins. Most species lack pectoral fin, pectoral and pelvic fins, adding to their serpentine appearance. Their eyes are rather small; morays rely mostly on their highly developed sense of smell, lying in wait to Ambush predator, ambush prey. The body is generally patter ...

Whitemouth Moray
The turkey moray (''Gymnothorax meleagris''),also known as the guineafowl moray or as the white-mouth/whitemouth moray is a species of marine fish in the family Muraenidae. Description The turkey moray is a medium size moray which can reach a maximum length of 120 cm, but specimens usually encountered are much smaller. Its serpentine in shape body has a dark brown to black background color dotted with numerous small white spots uniformly distributed. The inside of its mouth is completely white. Distribution and habitat The white-mouth moray is widespread throughout the Indo-Pacific area from eastern coast of Africa, Red Sea included, until Polynesia and Hawaii and from south Japan to New Caledonia. This is a relatively rare moray even within its distribution area except in Hawaii, where it seems to be common. It likes shallow waters from lagoons and reefs rich in coral and fish life until deep, spending time in holes in the reef to quickly emerge to grasp passing fish by ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycosylation
Glycosylation is the reaction in which a carbohydrate (or ' glycan'), i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule (a glycosyl acceptor) in order to form a glycoconjugate. In biology (but not always in chemistry), glycosylation usually refers to an enzyme-catalysed reaction, whereas glycation (also 'non-enzymatic glycation' and 'non-enzymatic glycosylation') may refer to a non-enzymatic reaction. Glycosylation is a form of co-translational and post-translational modification. Glycans serve a variety of structural and functional roles in membrane and secreted proteins. The majority of proteins synthesized in the rough endoplasmic reticulum undergo glycosylation. Glycosylation is also present in the cytoplasm and nucleus as the ''O''-GlcNAc modification. Aglycosylation is a feature of engineered antibodies to bypass glycosylation. Five classes of glycans are produced: * ''N''-linked glycans attached to a nitrogen of asparagi ...

Epidermis (skin)
The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermal layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss. The epidermis is composed of multiple layers of flattened cells that overlie a base layer ( stratum basale) composed of columnar cells arranged perpendicularly. The layers of cells develop from stem cells in the basal layer. The thickness of the epidermis varies from 31.2μm for the penis to 596.6μm for the sole of the foot with most being roughly 90μm. Thickness does not vary between the sexes but becomes thinner with age. The human epidermis is an example of epithelium, particularly a stratified squamous epithelium. The word epidermis is derived through Latin , itself and . Something related to or part of the epidermis is termed epidermal. Structure ...

Goblet Cell
Goblet cells are simple columnar epithelial cells that secrete gel-forming mucins, like mucin 2 in the lower gastrointestinal tract, and mucin 5AC in the respiratory tract. The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress. The term '' goblet'' refers to the cell's goblet-like shape. The apical portion is shaped like a cup, as it is distended by abundant mucus laden granules; its basal portion lacks these granules and is shaped like a stem. The goblet cell is highly polarized with the nucleus and other organelles concentrated at the base of the cell and secretory granules containing mucin, at the apical surface. The apical plasma membrane projects short microvilli to give an increased surface area for secretion. Goblet cells are typically found in the respiratory, reproductive and lower gastrointestinal tract and are surrounded by other columnar cell ...

Mucus
Mucus (, ) is a slippery aqueous secretion produced by, and covering, mucous membranes. It is typically produced from cells found in mucous glands, although it may also originate from mixed glands, which contain both Serous fluid, serous and mucous cells. It is a viscous colloid containing inorganic ions, inorganic salts, antimicrobial enzymes (such as lysozymes), Antibody, immunoglobulins (especially Immunoglobulin A, IgA), and glycoproteins such as lactoferrin and mucins, which are produced by goblet cells in the mucous membranes and submucosal glands. Mucus covers the Epithelium, epithelial cells that interact with outside environment, serves to protect the linings of the respiratory system, respiratory, Digestion#Digestive system, digestive, and Genitourinary system, urogenital systems, and structures in the Visual system, visual and auditory systems from pathogenic Fungus, fungi, bacteria and viruses. Most of the mucus in the body is produced in the gastrointestinal tract. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molar (tooth)
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name ''molar'' derives from Latin, ''molaris dens'', meaning "millstone tooth", from ''mola'', millstone and ''dens'', tooth. Molars show a great deal of diversity in size and shape across the mammal groups. The third molar of humans is sometimes vestigial. Human anatomy In humans, the molar teeth have either four or five cusps. Adult humans have 12 molars, in four groups of three at the back of the mouth. The third, rearmost molar in each group is called a wisdom tooth. It is the last tooth to appear, breaking through the front of the gum at about the age of 20, although this varies among individuals and populations, and in many cases the tooth is missing. The human mouth contains upper (maxillary) and lower (mandibular) molars. They are: maxillary first molar, maxillary second molar, maxillary third mol ...

Crustacean
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans ( oligostracans and multicrustaceans). The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zebra Moray
The zebra moray (''Gymnomuraena zebra'') is a species of marine fish in the family Muraenidae. It is the only member of the genus ''Gymnomuraena'', though it sometimes has been included in ''Echidna'' instead. Description The zebra moray is considered as a medium-sized fish even if it can reach a maximum length of 150 cm. However, the average size commonly observed is more of the order of 50 cm. It is densely banded dark and whitish, giving rise to its common name. Its snout is round and short. Distribution and habitat The zebra moray is widespread throughout the Indo-Pacific area from eastern coast of Africa until western coast of the Americas, including the Red Sea, Hawaii and Galápagos. The zebra moray is a benthic fish, its favorite habitat corresponds to the rocky or coral reef on coastal shallow water up to 40 meters deep. Biology ''Gymnomuraena zebra'' has a nocturnal activity and actively hunt its prey. Unlike most other moray eels, it feeds exclusively on ...

Snowflake Moray
The snowflake moray (''Echidna nebulosa''), also known as the clouded moray among many vernacular names, is a species of marine eel of the family Muraenidae. It has blunt teeth ideal for its diet of crustaceans, a trait it shares with the zebra moray (''Gymnomuraena zebra''). Its Hawaiian name is puhi-kapa, which originates from King Kamehameha I’s nickname. The genus name is derived from the Greek word ''echidna'' meaning "viper", and the species name, ''nebulosa,'' originates from the Latin word meaning "misty" or "cloudy". It is widespread throughout the Indo-Pacific area from the eastern coast of Africa throughout Micronesia including the Red Sea and to Hawaii. The species is also found in the eastern Central Pacific from southern Baja California, Mexico, and from Costa Rica to northern Colombia.McCosker, J.E. and R.H. Rosenblatt, 1995. Muraenidae.

Similan Islands
The Similan Islands (, , , Malay: ''Kepulauan Sembilan'') is a continental archipelago in the Andaman Sea off the coast of, and part of, Phang Nga Province in southern Thailand. It is the maritime border between India and Thailand. It was established as Mu Ko Similan National Park in 1982 after a one-year assessment by the forestry department. Access and tourism Access to the Similan Islands is primarily through Tab Lamu Port, located just south of Khao Lak in Phang Nga Province. The park headquarters is situated in Tab Lamu, a small fishing village approximately from Bang La On in Khao Lak. Regular boat services to the islands operate from the middle of October to the middle of May, with trips taking around three hours on standard boats and approximately 70 minutes by speedboat. During the diving season, liveaboard dive boats frequent the Similan Islands. These boats, departing from Tab Lamu, Ko Lanta, Phuket, and Ranong, offer multi-day stays in the Similan National Mari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
