Triprion
''Triprion'' is a genus of frogs (the shovel-headed tree frogs) in the family Hylidae found in the Pacific lowlands of Mexico, the Yucatán Peninsula, and Guatemala. These frogs hide in tree-holes and plug the entrance with their strange-looking, bony heads.

Triprion Spatulatus
''Triprion spatulatus'' is a species of frog in the family Hylidae. It is Endemism, endemic to the Pacific lowlands of western Mexico between the Sinaloa and Oaxaca states. It is known by several common names: shovel-headed treefrog, Mexican shovel-headed treefrog, shovel-nosed tree frog, and shovelhead treefrog. Taxonomy and systematics Two subspecies that primarily differ in coloration are sometimes distinguished: Duellman (1970) allocated specimens from Sinaloa to the nominotypical subspecies and those further south and east to ''T. s. reticulatus''. However, more recent research suggests that populations east of the Isthmus of Tehuantepec represent a distinct but yet undescribed species. Description ''Triprion spatulatus'' are large frogs, with males reaching and females in snout–vent length. The head has broad labial flanges, giving it a spoon-like shape, as attested in its Specific name (zoology), specific (from Latin ''spatulus'', "spoon") and vernacular names. The ey ...

Triprion Spinosus
''Triprion spinosus'', also known as the spiny-headed tree frog, spiny-headed treefrog, spinyhead treefrog, coronated treefrog, and crowned hyla, is a species of frog in the family Hylidae. It has a spotty distribution in Panama, Costa Rica, Honduras, and southern Mexico. Previously in its own monotypic genus ''Anotheca'' Smith, 1939, it was transferred to the genus ''Triprion'' in 2018. Description This species is a relative large frog with a snout–to–vent length of . It has numerous sharp, pointed projections on the head and dorsal surface, hence the common name. The skin on the head is fused to the skull and the tympanum is very large. The legs are long and slender and the digits have adhesive discs at the tips. The dorsal surface is pale brown or gray, with dark markings, and the flanks are dark brown or black, the colors being separated by a narrow white band. Ecology This species is active at night when the male's call "boop...boop...boop" is more likely to be hear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hylinae
Hylinae is a large subfamily of "tree frogs", family Hylidae. Classification The contents of this subfamily vary substantially according to the source. The Amphibian Species of the World follows the revision by Duellman and colleagues from 2016 based on molecular data and delimits the subfamily more narrowly than before, treating parts of former Hylinae as their own subfamilies. Following this classification, there were 18 genera totaling 174 species in the end of 2020. They are found North, Central, and the northmost South America, much of temperate Eurasia, Japan, and extreme northern Africa, however, only ''Hyla'' is found outside the Americas. The Wikipedia is following this classification. The AmphibiaWeb follows an older classification defining Hylinae more broadly, with several hundred species. At the end of 2020, the AmphibiaWeb lists 42 genera totaling 737 species. Amphibian Species of the World At the end of 2020, the Amphibian Species of the World includes the follo ...

Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as " tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** '' Boana'' – gladiator treefrogs *** '' Bokermannohyla'' *** '' Hyloscirtus'' *** '' Myersiohyla'' *** '' Nesorohyla'' *** ''"Hyla" nicefori'' ** Tribe Dendropsophini ***'' Dendropsophus'' *** '' Julianus'' *** '' Lysap ...

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] |
Frog
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" '' Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs ...

Yucatán Peninsula
The Yucatán Peninsula (, also , ; es, Península de Yucatán ) is a large peninsula in southeastern Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north and west of the peninsula from the Caribbean Sea to the east. The Yucatán Channel, between the northeastern corner of the peninsula and Cuba, connects the two bodies of water. The peninsula is approximately in area. It has low relief, and is almost entirely composed of porous limestone. The peninsula lies east of the Isthmus of Tehuantepec, the narrowest point in Mexico separating the Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea, from the Pacific Ocean. Some consider the isthmus to be the geographic boundary between Central America and the rest of North America, placing the peninsula in Central America. Politically all of Mexico, including the Yucatán, is generally considered part of North America, while Guatemala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibian Genera
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 d ...
