Pelobates Syriacus
''Pelobates syriacus'', the eastern spadefoot or Syrian spadefoot, is a species of toad in the family Pelobatidae, native to an area extending from Eastern Europe to Western Asia. Description The eastern spadefoot is a plump toad with a large head with a flat topped skull, large, protruding eyes and vertical slit-like pupils. It can grow to a length of about . The skin is smooth with a scattering of small warts. The male has a large gland at the back of his fore legs which becomes enlarged in the breeding season. The front foot has four toes and the back foot has five with deeply indented webbing between them. The hind legs are short and at the back of each hind foot is a yellowish bony protuberance, the inner metatarsal tubercle or spade, that gives the animal its name. The colour of the frog is quite variable, the back often being pale grey with large, greenish, irregularly shaped blotches and the belly being pale grey. The eastern spadefoot can be distinguished from the western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frogspawn (eggs) Of Pelobates Syriacus, Rehovot Vernal Pool, Israel 03
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), 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, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, 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 (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ponds
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be f ...

Tadpoles
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 been ...

Common Spadefoot
''Pelobates fuscus'' is a species of toad in the family Pelobatidae, native to an area extending from Central Europe to Western Asia. It is commonly known as the common spadefoot, garlic toad, the common spadefoot toad and the European common spadefoot. The common spadefoot grows to a length of approximately for males and for females. The skin colouration varies depending upon habitat, gender and region, but is usually light-grey to beige-brown on the dorsal surface. The skin is mottled by darker marks that differ between individuals. The belly is white, sometimes with grey mottling. Albino specimens have been observed. Two subspecies are traditionally recognised: ''Pelobates fuscus fuscus'' (from central Europe) and ''Pelobates fuscus insubricus'' (from Northern Italy). In reality there is no physical or behavioural character allowing to distinguish these supposed subspecies. A recent study showed that there is no haplotype segregation for the populations of Northern Italy, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
