Trachidermis
''Trachidermus fasciatus'' is a species of fish in the superfamily Cottoidea, the sculpins, and the only member of the monotypic genus ''Trachidermus''. Its common name is roughskin sculpin. It has also been called four-gilled perch. It is native to the coastlines of China, Japan, and Korea, where it occurs at the mouths of rivers. Description This species is up to about long and weighs up to . It has a large, spineless head with a wide mouth and small eyes near the tip of the snout. The upper jaw is slightly projecting. The dorsal fin has 8 spines and 19 to 20 soft rays and the anal fin has no spines but 17 to 18 soft rays. This fish lacks scales but its body surface is textured with knobbles. The gill opening is large and each gill has two orange stripes. This fish lives in rivers, estuaries, and coastal ocean waters. It is catadromous; adults spawn on mudflats at the river mouths, and after hatching, the juveniles swim upstream to freshwater river habitat. Breeding The f ...

Zoological Specimen
A zoological specimen is an animal or part of an animal preserved for scientific use. Various uses are: to verify the identity of a (species), to allow study, increase public knowledge of zoology. Zoological specimens are extremely diverse. Examples are bird and mammal study skins, mounted specimens, skeletal material, casts, pinned insects, dried material, animals preserved in liquid preservatives, and microscope slides. Natural history museums are repositories of zoological specimens Study skins Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center. The dowel is often intentionally longer than the bird's body and exits at the animal's vent. This exposed dowel provides a place to handle the bird without distu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crassostrea Rivularis
''Crassostrea'' is a genus of true oysters (family Ostreidae) containing some of the most important oysters used for food. The genus was recent split in WoRMS, following the DNA-based phylogenies of Salvi ''et al.'' (2014 and 2017). Pacific species were moved to a new genus ''Magallana''. ''C. zhanjiangensis'' became '' Talonostrea zhanjiangensis''. The changes are not universally welcomed by oyster researchers, as ''C. gigas'' (now ''M. gigas'') is "one of the most researched species of marine invertebrate". Species Extant species are: Fossil species Fossil species include: * †''Crassostrea alabamiensis'' (Lea 1833) * †''Crassostrea ashleyi'' ( Hertlein 1943) (syn. ''Ostrea arnoldi'') * †''Crassostrea cahobasensis'' (Pilsbry and Brown 1910) * †''Crassostrea contracta'' (Conrad 1865) * †''Crassostrea cucullaris'' (Lamarck 1819) * †''Crassostrea cuebana'' (Jung 1974) * †''Crassostrea elegans'' (Deshayes, 1832) (syn. †''Cubitostrea elegans'' Deshayes 1832 or ...

Copepod
Copepods (; meaning 'oar-feet') are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (living in the water column), some are benthos, benthic (living on the sediments), several species have Parasitism, parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calanoida
Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them. Description Calanoids can be distinguished from other planktonic copepods by having first antennae at least half the length of the body and biramous second antennae. However, their most distinctive anatomical trait is the presence of a joint between the fifth and sixth body segments. The largest specimens reach long, but most do not exceed long. Classification The order Calanoida contains the following families: * Acartiidae * Aetideidae * Arctokonstantinidae * Arietellidae * Augaptilidae * Bathypontiidae * Calanidae * Candaciidae * Centropagidae * Clausocalanidae * Diaixidae * Diaptomidae * Discoidae * Epacteriscidae * Eucalanidae * Euchaetidae * Fosshageniidae * Heterorhabdidae * Hyperbionycidae * Kyphocalanidae * Lucicutiidae * Megacalanidae * Me ...

Ariake Sea
The is a body of salt water surrounded by Fukuoka, Saga, Nagasaki, and Kumamoto Prefectures, all of which lie on the island of Kyūshū in Japan. It is the largest bay in Kyūshū. Its deepest point is only about 50 meters (165 ft) deep, and extreme tides exceed , covering roughly . Isahaya Bay is a branch of the Ariake Sea. Across the Amakusa Islands lies the Yatsushiro Sea. Many harbors are located on the coast of the Ariake Sea. Among them are Misumi (in the city of Uki, Kumamoto Prefecture), Shimabara ( Shimabara, Nagasaki), Taira ( Unzen, Nagasaki), Nagasu ( Nagasu, Kumamoto), Kumamoto ( Kumamoto, Kumamoto), Miike ( Omuta, Fukuoka), Kuchinotsu ( Minamishimabara, Nagasaki), and Oniike ( Amakusa, Kumamoto). Five ferry routes cross the Ariake Sea. Various species of fauna, including mudskippers, pen shells (''Atrina pectinata''), and fiddler crabs, live in the Ariake Sea. In autumn, the '' Suaeda'' halophyte ''shichimenso'' ('' Suaeda japonica'') grows along the shore. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotifer
The rotifers (, from Latin 'wheel' and 'bearing'), sometimes called wheel animals or wheel animalcules, make up a phylum (Rotifera ) of microscopic and near-microscopic Coelom#Pseudocoelomates, pseudocoelomate animals. They were first described by John Harris (writer), Rev. John Harris in 1696, and other forms were described by Antonie van Leeuwenhoek in 1703. Most rotifers are around long (although their size can range from to over ), and are common in freshwater environments throughout the world with a few Seawater, saltwater species. Some rotifers are free swimming and truly planktonic, others move by inchworming along a substrate, and some are Sessility (zoology), sessile, living inside tubes or gelatinous holdfast (biology), holdfasts that are attached to a substrate. About 25 species are colonial (e.g., ''Sinantherina semibullata''), either sessile or planktonic. Rotifers are an important part of the freshwater zooplankton, being a major foodsource and with many specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zooplankton
Zooplankton are the heterotrophic component of the planktonic community (the " zoo-" prefix comes from ), having to consume other organisms to thrive. Plankton are aquatic organisms that are unable to swim effectively against currents. Consequently, they drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton (cyanobacteria and microalgae), which are the plant-like component of the plankton community (the " phyto-" prefix comes from , although taxonomically ''not'' plants). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding), often generating biological energy and macromolecules through chlorophyllic carbon fixation using sunlightin other words, zooplankton cannot manufacture their own food, while phytoplankton can. As a result, zooplankton must acquire nutrients by feeding on other organisms such as phytoplankton, which are generally smaller t ...

Shrimp
A shrimp (: shrimp (American English, US) or shrimps (British English, UK)) is a crustacean with an elongated body and a primarily Aquatic locomotion, swimming mode of locomotion – typically Decapods belonging to the Caridea or Dendrobranchiata, although some Shrimp#Non-decapods, crustaceans outside of this order are also referred to as "shrimp". Any small crustacean may also be referred to as "shrimp", regardless of resemblance. More narrow definitions may be restricted to Caridea, to smaller species of either of the aforementioned groups, or only the Marine life, marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (Abdomen#Arthropoda, abdomens), long whiskers (Antenna (biology), antennae), and slender, Biramous, biramous legs. They swim forward by paddling the swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks wit ...

Predation
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 List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tangerine (color)
The color tangerine is a tone of orange named after the fruit of the same name. Use in graphic design Hues of tangerine are sometimes important to graphic designers when constructing identities, brand recognition, and stand-out ads for clients. Because of the brightness of the color variants, they are often employed to make a small but centrally important object stand out, especially when surrounded by the flat colors of earth tones. Tangerine hues may also be selected as complements to other bright hues, and because of their relative rarity of use. One of the original "fruit-flavored" iMacs released in 1999 was the Tangerine iMac (Apple could not call it "Orange" due to the existence of the rival firm Orange Micro). In sports, the English association football club Blackpool play in and are strongly identified with the color of tangerine since 1923.

Glass Bottle
Common uses for bottles made from glass include food condiments, soda, liquor, cosmetics, pickling and preservatives; they are occasionally also notably used for the informal distribution of notes. A glass bottle can vary in size considerably, but are most commonly found in sizes ranging between about 200 millilitres and 1.5 litres. History Glass bottles and glass jars are found in many households worldwide. The first glass bottles were produced in Mesopotamia around 1500 B.C., and in the Roman Empire in around 1 AD. America's glass bottle and glass jar industry was born in the early 1600s, when settlers in Jamestown built the first glass-melting furnace. The invention of the automatic glass bottle-blowing machine in 1903 industrialized the process of making bottles. Manufacture The earliest bottles or vessels were made by ancient man. Ingredients were melted to make glass and then clay forms were dipped into the molten liquid. When the glass cooled off, the clay was chip ...

Bamboo
Bamboos are a diverse group of mostly evergreen perennial plant, perennial flowering plants making up the subfamily (biology), subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family, in the case of ''Dendrocalamus sinicus'' having individual stalks (Culm (botany), culms) reaching a length of , up to in thickness and a weight of up to . The internodes of bamboos can also be of great length. ''Kinabaluchloa, Kinabaluchloa wrayi'' has internodes up to in length. and ''Arthrostylidium schomburgkii'' has internodes up to in length, exceeded in length only by Cyperus papyrus, papyrus. By contrast, the stalks of the tiny bamboo Raddiella, ''Raddiella vanessiae'' of the savannas of French Guiana measure only in length by about in width. The origin of the word "bamboo" is uncertain, but it most likely comes from the Dutch language, Dutch or Portuguese language, Portuguese language, which originally borrowed it from Malay langua ...
