Amphibian
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Amphibious Caterpillar
Amphibious caterpillar refers to over 40 species of semiaquatic caterpillars endemic to Hawaii that are the only insect larvae that live as readily in water as on land. In 2010, Daniel Rubinoff and Patrick Schmitz at the University of Hawaii at Manoa first described the amphibious habits of the larvae in the moth genus '' Hyposmocoma'' of the family Cosmopterigidae. Young of each species thrive both underwater in rushing streams and exposed to air on rocks poking out of the water. Rubinoff states, "These species are at least as different as chimpanzees are from us". While some other caterpillars can survive for short periods under water, they are possibly the only air-breather that can thrive exclusively there. "No other animal that breathes air can handle being submerged for a month", he says. These caterpillars do not have gills or anything that covers the trachea to operate marine mammals' surface-to-breathe technique for respiration. Instead they appear to absorb oxygen ...

Amphibious Fish
Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits, a process known as convergent evolution. These fish use a range of methods for land movement, such as lateral undulation, tripod-like walking (using paired fins and tail), and jumping. Many of these methods of locomotion incorporate multiple combinations of pectoral-, pelvic-, and tail-fin movement. Many ancient fish had lung-like organs, and a few, such as the lungfish and bichir, still do. Some of these ancient "lunged" fish were the ancestors of tetrapods. In most recent fish species, though, these organs evolved into the swim bladders, which help control buoyancy. Having no lung-like organs, modern amphibious fish and many fish in oxygen-poor water use other methods, such as their gills or their skin to breathe air. Amphibious fish may also ...

Aquatic Insect
Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some ''diving'' insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete. Breathing One problem that aquatic insects must overcome is how to get oxygen while they are under water. Almost all animals require a source of oxygen to live. Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment with the specialization of these structures ;Aquatic adaptations # Simple diffusion over a relatively thin integument # Temporary use of an air bubble # Extraction of oxygen from water using a plastron or blood gill # Storage of oxygen in hemoglobin and hemocyanin molecules in hemolymph # Taking oxygen from surface via brea ...

Scolopendra Cataracta
''Scolopendra cataracta'' is a species of centipede in the family Scolopendridae. It is the first known amphibious centipede and grows to up to in length. Description ''Scolopendra cataracta'' is a giant centipede, growing to around in length; it has long legs and a greenish-black colour. When exposed, it escapes into water. It both runs along stream beds and swims with eel-like horizontal undulations of its body. Out of water, water rolls off the centipede's body leaving it dry as the surface is hydrophobic. The species was discovered, and the first specimen collected, in 2000 near Thailand's Khao Sok National Park. Two more specimens were collected near waterfalls in Laos. DNA analysis confirmed they belonged to ''S. cataracta''; the new species was named for the Latin for waterfall. A further specimen was found in the Natural History Museum's collection, in the shape of a misidentified 1928 centipede from Vietnam. The ecological niche is conjectured to be based on goi ...

Amphibius (comics)
The Savage Land Mutates is a supervillain group appearing in American comic books published by Marvel Comics. Their creators were writer Roy Thomas and penciler Neal Adams. Within the comic books, the group is based in an imaginary place called the Savage Land, which is a hidden Antarctic environment inhabited by dinosaurs and primitive humans. Publication history The Savage Land Mutates first appeared in ''The X-Men'' #62 (November 1969) and were created by Roy Thomas and Neal Adams. Fictional team biography The Savage Land Mutates were originally humanoid inhabitants of the Savage Land who were genetically altered by Magneto to serve as his troops. They clashed with the X-Men and Ka-Zar on multiple occasions. On one occasion, they turned Spider-Man into the Man-Spider and Angel into a bird monster. They have also encountered the Avengers. Although the group is fairly large, most appearances of the group contain only about half of the group's members, usually under lea ...

Amphibious Aircraft
An amphibious aircraft, or amphibian, is an aircraft that can Takeoff, take off and Landing, land on both solid ground and water. These aircraft are typically Fixed-wing aircraft, fixed-wing, though Amphibious helicopter, amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes (flying boats and floatplanes) which are equipped with Landing gear, retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared with planes designed specifically for land-only or water-only operation. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the de Havilland Canada DHC-3 Otter, DHC Otter, incorporate retractable wheels within their floats. Some amphibians are fitted with reinforced keels which act as skis, allowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Vehicle
An amphibious vehicle (or simply amphibian) is a vehicle that works both on land and on or under water. Amphibious vehicles include amphibious Amphibious cycle, bicycles, Amphibious ATV, ATVs, Amphibious automobile, cars, Duckboats, buses, trucks, Railroad car, railway vehicles, combat vehicles, and hovercraft. Classic landing craft are not amphibious vehicles as they do not work on land, although they are part of amphibious warfare. Ground effect vehicles, such as ''ekranoplans'', will likely crash on any but the flattest of landmasses so are also not considered to be amphibious vehicles. General technical notes Two main categories of amphibious vehicles are those that travel on an air cushion (Hovercraft) and those that do not. Among the latter, many extend the off-road capabilities of land vehicles to all kinds of terrain, including ice, snow, mud, marsh, swamp etc. This explains why many designs use Tracked vehicle, tracks in addition to or instead of wheels, and in som ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named '' Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, sca ...
