Tomato Frog
Tomato frogs are any of the three species of genus ''Dyscophus'' (family Microhylidae): ''D. antongilii'', ''D. insularis'', or ''D. guineti''. ''Dyscophus'' is the only genus in subfamily Dyscophinae. They are endemic to Madagascar. The common name comes from ''D. antongiliis bright red color. When threatened, a tomato frog puffs up its body. When a predator grabs a tomato frog in its mouth, the frog's skin secretes a thick substance that numbs up the predator's eyes and mouth, causing the predator to release the frog to free up its eyes. The gummy substance contains a toxin that occasionally causes allergic reactions in humans. The allergic reaction will not kill a human and the frog secretes it only when frightened. The lifespan of the tomato frog can be from 6 to 8 years. When adult, the colors may vary from yellowish orange to deep red. Tomato frogs will reach sexual maturity in 9–14 months. Females are larger than males and can reach 4 inches in length. Males can reach 2 ...

Dyscophus Antongilii
''Dyscophus antongilii'', the Madagascar tomato frog, is a species of frog in the family Microhylidae. Description Females are much larger than males, reaching up to 10.5 cm and 230 g in weight (6.5 cm and 41 g for males). Tomato frogs live up to their name by possessing a vibrant, orange-red colour. Females have brighter tones of red or orange on their back, with a pale undersurface. Some individuals also have black spots on the throat. It is thought that the brilliant colours of the tomato frog act as a warning to potential predators that these frogs are toxic; a white substance secreted from the skin acts as a glue to deter predators (such as colubrid snakes) and can produce an allergic reaction in humans. Habitat and distribution Endemic to Madagascar, tomato frogs are found in the northeast of the island around Antongil Bay (from which they gain their specific name, antongilii), and south to Andevoranto. The exact distribution of this species is unclear however, ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50  μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Dyscophus Insularis
''Dyscophus insularis'' is a species of frog in the family Microhylidae. It is endemic to western Madagascar (the two other '' Dyscophus'' species are from eastern Madagascar). Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, dry savanna, moist savanna, intermittent rivers, and intermittent freshwater marshes. It is threatened by 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 ....

Dyscophus Guineti
''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).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French naturalist and 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. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet, but was prevented by a severe attack of fever. ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...
