Alcalus
''Alcalus'' is a small genus of frogs in the family Ceratobatrachidae. It is the only member of the subfamily Alcalinae. Its sister taxon is Ceratobatrachinae. Common name Alcala's dwarf mountain frogs has been proposed for the genus. They are found in Palawan Island (the Philippines), Borneo, and the Malay Peninsula. They prefer semi-aquatic microhabitats. Etymology The genus is named in honour of Angel Alcala, a Filipino biologist who has worked with Southeast Asian amphibians. Description Compared to the closely related genera ''Cornufer'' and ''Platymantis'', ''Alcalus'' have an intermediate body size (based on '' Alcalus baluensis'' and '' A. mariae'', males measure and females in snout–vent length). The head is broad. Skin is coarsely textured, shagreened, or ‘wrinkled’ in appearance. The toe discs are widely expanded; inter-digital webbing is extensive. Males have nuptial pads but lack vocal sac The vocal sac is the flexible membrane of skin possessed by mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alcalus Mariae
''Alcalus mariae'', common name Mary's frog or Palawan eastern frog, is a species of frog in the family Ceratobatrachidae. It is endemic to the Palawan Island, the Philippines, and only known from its type locality, Mount Balabag, in the Mantalingajan mountain range. The specific name refers to Mary Lee Inger née Ballew, first wife of Robert F. Inger who formally described the species in 1954. Description The type series of ''Alcalus mariae'' consists of two males measuring in snout–vent length. They are stocky frogs with depressed, broad head and rounded snout. Tympanum is visible though rim hidden by skin. Tips of digits are expanded into large, round disks. Legs are stout and relatively short. Toes are webbed and have disks similar in size to those on fingers. Skin of all dorsal surfaces is coarsely shagreen. Chest and belly are strongly rugose but gular region is less so. Tubercles are present laterally. Habitat and conservation The natural habitat of ''Alcalus mariae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcalus Rajae
''Alcalus rajae'', sometimes known as king dwarf mountain frog, is a species of frog in the family Ceratobatrachidae, subfamily Alcalinae. It is endemic to Kalimantan, Borneo (Indonesia), and known from its type locality in the Bukit Baka Bukit Raya National Park, as well as the Gunung Penrissen Nature Reserve, both in the West Kalimantan province, and from the Meratus Protected Forest in the South Kalimantan province. The specific name ''rajae'' refers to the type locality: Bukit Raya is the highest mountain in Kalimantan, getting its name from the Indonesian word ''raya'' (or ''raja''), signifying the majestic size of the peak.

Ceratobatrachidae
The Ceratobatrachidae are a family of frogs found in the Malay Peninsula, Borneo, the Philippines, Palau, Fiji, New Guinea, and the Admiralty, Bismarck, and Solomon Islands. Taxonomy Ceratobatrachidae was formerly treated as a subfamily (i.e., Ceratobatrachinae) in the family Ranidae (true frogs), but have now been re-classified as a separate family. The following genera are recognised: * Subfamily Alcalinae Brown, Siler, Richards, Diesmos, and Cannatella, 2015 ** '' Alcalus'' (5 species) * Subfamily Ceratobatrachinae Boulenger, 1884 **'' Cornufer'' Tschudi, 1838 (> 50 species) **''Platymantis'' Günther, 1858 (> 30 species) * Subfamily Liuraninae Fei, Ye, and Jiang, 2010 **'' Liurana'' Dubois, 1987 (4 species) Formerly, the following genera were also recognized in the family Ceratobatrachidae, but have now been merged into the genera above. *'' Batrachylodes'' Boulenger, 1887 (8 species) *'' Palmatorappia'' Ahl, 1927 (1 species) *'' Ceratobatrachus'' Boulenger, 1884 (1 spe ...

Taxa Named By David C
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...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 ...

Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...
