False Tomato Frog
''Dyscophus guineti'', the false tomato frog or the Sambava tomato frog, is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss. Description The ''Dyscophus'' ''guineti'' male frogs are yellowish, and in size 60-65mm. The female frogs are red- orange often with many small reticulations, in size 90-95mm. Some of these frogs have an Odontoma which are tumors from a tooth that also contain tissue. These cause bad tooth eruption and displacement Displacement may refer to: Physical sciences Mathematics and physics *Displacement (geometry), is the difference between the final and initial position of a point trajectory (for instance, the center of mass of a moving object).

Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French natural history, naturalist and List of explorers, explorer. From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey. They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest. The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet Museum, Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odontoma
An odontoma, also known as an odontome, is a benign tumour linked to tooth development. Specifically, it is a dental hamartoma, meaning that it is composed of normal dental tissue that has grown in an irregular way. It includes both odontogenic hard and soft tissues. As with normal tooth development, odontomas stop growing once mature which makes them benign. The average age of people found with an odontoma is 14. The condition is frequently associated with one or more unerupted teeth and is often detected through failure of teeth to erupt at the expected time. Though most cases are found impacted within the jaw there are instances where odontomas have erupted into the oral cavity. Types There are two main types: compound and complex. * A ''compound'' odontoma consists of the four separate dental tissues ( enamel, dentine, cementum and pulp) embedded in fibrous connective tissue and surrounded by a fibrous capsule. It may present a lobulated appearance where there is no defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1875
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...
