Xenophrys Longipes (2)
''Xenophrys longipes'' is a species of frog in the family Megophryidae. It is also known as the Malacca spadefoot toad, red legged spine-eyed frog, red-legged horn frog, and slender-legged horned frog. It is found in the Malay Peninsula (Peninsular Malaysia and southern Thailand and Burma). Records from Cambodia and Vietnam are considered doubtful. Description Male ''Xenophrys longipes'' grow to snout-vent length of and females to . The body is relatively slender, as are the long hind legs. The tympanum is distinct. The dorsal skin is smooth but there are small warts on the flanks. The supratympanic fold is distinct and there are two pairs of delicate, oblique folds that converge posteriorly on the scapular region. The ventral surface is smooth. The dorsum is olive brown. There are oblique vertical dark bars on the sides of the head and a large triangular dark marking between the eyes. The limbs have dark cross-bars. The ventrum is pale reddish brown marbled and spotted with da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khao Sok National Park
Khao Sok National Park ( th, เขาสก, ) is in Surat Thani Province, Thailand. Its area is 461,712 rai ~ , and it includes the Cheow Lan Lake contained by the Ratchaprapha Dam. The park is the largest area of virgin forest in southern Thailand and is a remnant of rain forest which is older and more diverse than the Amazon rain forest. Geography Beautiful sandstone and mudstone rocks rise about above sea level. The park is traversed by a limestone mountain range from north to south with a high point of . This mountain range is hit by monsoon rain coming from both the Gulf of Thailand and the Andaman Sea, which makes it among Thailand's wettest regions with an annual rain fall of . Heavy rainfall and falling leaves led to the erosion of the limestone rocks and created the significant karst formations seen today. Flora Bamboo holds topsoil very tenaciously, preventing soil erosion on hillsides and riverbanks. With more than 1,500 species, bamboo is the oldest grass in the ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Amphibians Described In 1886
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within 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 recent decades there has been a dramatic decline ...

Xenophrys
''Xenophrys'' is a genus of amphibians in the family Megophryidae. They are found in southeastern Asia (including China and northeastern India) to Borneo. Their common name is strange-horned toads. Conservation Of the 36 ''Xenophrys'' species that the International Union for Conservation of Nature has evaluated, most are either " Data Deficient" or of "Least Concern". However, one species is considered " Critically Endangered" ('' Xenophrys damrei'') "Endangered" ('' Xenophrys takensis''), one is " Vulnerable" ('' Xenophrys auralensis''), and six are "Near Threatened". Taxonomy The genus was previously found to be strongly polyphyletic, and awaiting a better solution, they were synonymized in the genus ''Megophrys''. Following subsequent studies and reclassification, the genus has been revalidated. Species Presently, '' Amphibian Species of the World'' classifies the following 31 species in ''Xenophrys'': * '' Xenophrys aceras'' (Boulenger, 1903) — Perak horned toad * ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...
