Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Caterpillar
Amphibious caterpillar refers to over 40 species of semiaquatic caterpillars endemic to Hawaii that are the only insects 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 don’t have gills or anything that covers the trachea to operate marine mammals' surface-to-breathe technique for respiration. Instead they appear to absorb oxygen direct ...

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 terrestrial locomotory modes, such as lateral undulation, tripod-like walking (using paired fins and tail), and jumping. Many of these locomotory modes 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 have ey ...

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 molecules in hemolymph # Taking oxygen from surface via breathing tubes ( siph ...

Scolopendra Cataracta
''Scolopendra cataracta'' is a species of centipede in the family Scolopendridae. It is the first known amphibious centipede, growing to up to in length. Discovery George Beccaloni, an entomologist and curator at the Natural History Museum, London, found a specimen of ''S. cataracta'' near the Khao Sok National Park in 2000, while on honeymoon in Thailand. Beccaloni described the centipede as "pretty horrific-looking: very big with long legs and a horrible dark, greenish-black colour" but what caught his attention was that it scurried into a stream rather than the forest when he turned over the stone it was hiding under on the stream bank – unusual behaviour as centipedes typically avoid water. It then ran along the stream bed and hid under a rock underwater. After capturing the centipede, Beccaloni observed that it swam like an eel below the water's surface; his discovery was greeted with scepticism by an expert on ''Scolopendra'', as these centipedes usually occur in ...

Amphibius (comics)
The Savage Land Mutates is a supervillain group of criminals appearing in American comic books published by Marvel Comics. Their creators were writer Roy Thomas and the penciler/inker team of Neal Adams and Tom Palmer. Within the comic books, the group is based in the imaginary place called the Savage Land, which is a hidden Antarctic environment of dinosaurs and primitive humans within Marvel Comics' fictional Marvel Universe. Publication history The Savage Land Mutates first appeared in ''The X-Men'' #62 and were created by Roy Thomas, Neal Adams, and Tom Palmer. Fictional team biography The Savage Land Mutates were originally the human inhabitants of the Savage Land (most of them being from the Swamp Men tribe) that were genetically altered by the mutant Magneto to serve as his troops. The mutations in the Savage Land were occurring easy due to the levels of radiation. They clashed with the X-Men and Ka-Zar on multiple occasions. On one occasion, they turned Spider-Man into ...

Amphibious Aircraft
An amphibious aircraft or amphibian is an aircraft (typically fixed-wing) that can take off and land on both solid ground and water, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes ( flying boats and floatplanes) which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up. 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 DHC Otter, incorporate retractable wheels within their floats. Many amphibian aircraft are of the flying boat type. These aircraft, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Vehicle
An amphibious vehicle (or simply amphibian), is a vehicle that is a means of transport viable on land as well as on or under water. Amphibious vehicles include amphibious bicycles, ATVs, cars, buses, trucks, railway vehicles, combat vehicles and hovercraft. Classic landing craft are not amphibious vehicles as they do not offer any real land transportation at all, 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 Apart from the distinction in sizes mentioned above, two main categories of amphibious vehicles are immediately apparent: those that travel on an air-cushion ( Hovercraft) and those that do not. Amongst the latter, many designs were prompted by the desire to expand the off-road capabilities of land-vehicles to an "all-terrain" ability, in some cases not only focused on creating a tr ...

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, scale an ...
