Muraenidae
Moray eels, or Muraenidae (), are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water. The English name, from the early 17th century, derives from Portuguese , which itself derives from Latin , in turn from 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 and anal fins. Most species lack 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 prey. The body is generally patterned. In some species, the inside of the mouth is also patterned. Their jaws are wide, framing a protruding snout. Most possess large teeth used to tear flesh or grasp slipper ...

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 (biology), 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 Kamehameha I, King Kamehameha I’s nickname. The genus name is derived from the Greek word ''Echidna (fish), echidna'' meaning "viper", and the species name, ''nebulosa,'' originates from the Latin word ''nebulosus'' 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 Pacific Ocean, Central Pacific from southern Baja California, Mexico, and from Costa Rica to northern Colombia.McCosker, J.E. and R.H. Rosenblatt, 1995.

California Moray
The California moray (''Gymnothorax mordax'') is a moray eel of the family Muraenidae, found in the eastern Pacific from just north of Santa Barbara to Santa Maria Bay in Baja California. They are the only species of moray eel found off California, and one of the few examples of a subtropical moray. They typically occupy boulder or cobble habitats up to 40 m in depth. They can attain lengths of about 5 ft (1.52 m) and are believed to live for upwards of 22–26 years. Like other morays, they have no pelvic or pectoral fins or gill covers. Habitat and distribution California morays are a common sight on rocky reefs surrounding islands in southern California (notably, Catalina Islandin the California Channel Islands) and other islands in the Pacific. Their geographic distribution extends from Point Conception, California to Magdalena Bay, Baja California. California moray juveniles can live in tide pools while adults live in deeper waters. Adult California morays have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharyngeal Jaw
Pharyngeal jaws are a "second set" of jaws contained within an animal's throat, or pharynx, distinct from the primary or oral jaws. They are believed to have originated as modified gill arches, in much the same way as oral jaws. Originally hypothesized to have evolved only once, current morphological and genetic analyses suggest at least two separate points of origin. Based on connections between musculoskeletal morphology and dentition, diet has been proposed as a main driver of the evolution of the pharyngeal jaw. A study conducted on cichlids showed that the pharyngeal jaws can undergo morphological changes in less than two years in response to their diet. Fish that ate hard-shelled prey had a robust jaw with molar-like teeth fit for crushing their durable prey. Fish that ate softer prey, on the other hand, exhibited a more slender jaw with thin, curved teeth used for tearing apart fleshy prey. These rapid changes are an example of phenotypic plasticity, wherein environmental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Respiration
Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water. Unicellular and simple small organisms In very small animals, plants and bacteria, simple diffusion of gaseous metabolites is sufficient for respiratory function and no special adaptations are found to aid respiration. Passive diffusion or active transport are also sufficient mechanisms for many larger aquatic animals such as many worms, jellyfish, sponges, bryozoans and similar organisms. In such cases, no specific respiratory organs or organelles are found. Higher plants Although higher plants typically use carbon-dioxide and excrete oxygen during photosynthesis, they also respire and, particularly during darkness, many plants excrete carbon-dioxide and require oxygen to maintain normal functions. In fully submerged aquatic higher plants spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mucins
Mucins () are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. Mucins' key characteristic is their ability to form gels; therefore they are a key component in most gel-like secretions, serving functions from lubrication to cell signalling to forming chemical barriers. They often take an inhibitory role. Some mucins are associated with controlling mineralization, including nacre formation in mollusks, calcification in echinoderms and bone formation in vertebrates. They bind to pathogens as part of the immune system. Overexpression of the mucin proteins, especially MUC1, is associated with many types of cancer. Although some mucins are membrane-bound due to the presence of a hydrophobic membrane-spanning domain that favors retention in the plasma membrane, most mucins are secreted as principal components of mucus by mucous membranes or are secreted to become a component of saliva. Genes Human mucins ... [...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 (though in practice, 'glycation' often refers more specifically to Maillard-type reactions). 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 clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidermis (skin)
The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermis 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 human epidermis is a familiar 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 Cellular components The epidermis primarily consists of keratinocytes ( proliferating basal and differentiated suprabasal), which comprise 90% of its cells, but also contains melanocytes, Langerhans c ...
