Plumed Basilisk
The plumed basilisk (''Basiliscus plumifrons''), also called the green basilisk, double crested basilisk, or Jesus Christ lizard, is a species of lizard in the family Corytophanidae. The species is native to Central America. The plumed basilisk's native range spans southern Mexico and northern Colombia. ''B. plumifrons'' inhabits hot, humid rainforests that contain streams, rivers or other water bodies. The physical appearance of the plumed basilisk is striking: it sports a bright green color along its body with black and white streaks along its neck and back. Their physical appearance differs by sex, as they are sexually dimorphic; males have a distinct crest on the back and tail and large plumes on top of their heads, while females typically only have a singular, much smaller, crest on their head. The green crested or plumed lizard is unique in its ability to run across water with speed and the method it employs to do this. It displays the behaviour as a threat response, when ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juvenile (organism)
A juvenile is an individual organism that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as eclosion in many insects. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species, for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates, on reaching the adult stage, are fully mature and their development and growth stops. Their juveniles are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, and "juvenile" refers to a post-larval stage that is no ...

Anolis Aquaticus
''Anolis aquaticus'', commonly known as the water anole, is a semi-aquatic species of anole, a lizard in the family Dactyloidae, native to southwestern Costa Rica and far southwestern Panama. The species demonstrates adaptations that allows it to spend periods of time underwater up to approximately a quarter of an hour, forming an air bubble which clings to its head and serves to recycle the animal's air supply while it spends time beneath the surface. Although highly unusual, similar adaptions and behavior are found in other species of semi-aquatic anoles. Taxonomy The order of the water anole is Squamata, which refers to scaled reptiles. Squamata is the largest order of reptiles, including species of lizards, snakes, and amphisbaenians. Members of this order are found on every continent other than Antarctica, and they live in a variety of habitats, while showcasing various different traits. Iguania is a suborder that includes species of chameleons, iguanas, and New World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Geographic Society
The National Geographic Society (NGS), headquartered in Washington, D.C., United States, is one of the largest non-profit scientific and educational organizations in the world. Founded in 1888, its interests include geography, archaeology, and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. The National Geographic Society's logo is a yellow portrait frame—rectangular in shape—which appears on the margins surrounding the front covers of its magazines and as its television channel logo. Through National Geographic Partners (a joint venture with The Walt Disney Company), the Society operates the magazine, TV channels, a website, worldwide events, and other media operations. Overview The National Geographic Society was founded on 13 January 1888 "to increase and diffuse geographic knowledge".

Fluid Dynamics
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including '' aerodynamics'' (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space a ...

Air Cavity System
Air cavity system (or ACS) is a modern marine hull design concept based upon capturing air beneath a vessel's hull to reduce drag and increase speed and fuel efficiency. How it works The system works by trapping a layer of air bubbles beneath the ship's hull. A dedicated system or an air blower generates air bubbles that pass nonstop under the ship's surface. Along the bottom of the hull, air bubble outlets are located at different sites equally on both the sides of the boat's center. A layer of bubbles is formed by blowing air at a constant rate, reducing the drag and resistance between the boat and the water. Operational use ACS is used on the Russian Serna- and Dyugon-class landing crafts. See also *Froude number *Hull (watercraft) *Ship resistance and propulsion A ship must be designed to move efficiently through the water with a minimum of external force. For thousands of years ship designers and builders of sailing vessels used rules of thumb based on the midship-sect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaysian Sail-finned Lizard
The Moluccan sail-finned lizard or Ambon sailfin dragon (''Hydrosaurus amboinensis'') is a large agamid lizard native to moluccas or maluku islands in indonesia, growing to about in length. It is often confused for being the largest of the sailfin dragons; however, that title belongs to '' Hydrosaurus microlophus'', with the second largest of the sailfin dragons being '' Hydrosaurus celebensis''. The Amboina sail-finned lizard is found in wooded habitats near water in New Guinea and the central Moluccas. Although it has been reported from the Philippines and Sulawesi, a genetic study has shown that all in the former country (even southern ones, which have caused confusion in the past) are Philippine sailfin lizards ''H. pustulatus'', while genetic and morphological studies have shown that individuals from the latter island belong to two separate species to which the names ''H. celebensis'' and ''H. microlophus'' are available.Cameron D.

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbae ...

Coati
Coatis, also known as coatimundis (), are members of the family Procyonidae in the genera '' Nasua'' and '' Nasuella''. They are diurnal mammals native to South America, Central America, Mexico, and the southwestern United States. The name "coatimundi" comes from the Tupian languages of Brazil, where it means "lone coati". Locally in Belize, the coati is known as "quash". Physical characteristics Adult coatis measure from head to the base of the tail, which can be as long as their bodies. Coatis are about tall at the shoulder and weigh between , about the size of a large house cat. Males can become almost twice as large as females and have large, sharp canine teeth. The measurements above relate to the white-nosed and South America coatis. The two mountain coatis are smaller. All coatis share a slender head with an elongated, flexible, slightly upward-turned nose, small ears, dark feet, and a long, non-prehensile tail used for balance and signaling. Ring-tailed coatis ...
