Ancylometes Rufus
''Ancylometes rufus'' is a species from the genus '' Ancylometes''. The species was originally described by Charles Athanase Walckenaer in 1837. It is typically found near water. It has been seen predating on frogs, '' Dendropsophus melanargyreus'' and ''Ameerega trivittata ''Ameerega trivittata'',Grant, T. et al., (2006).

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Ancylometes
''Ancylometes'' is a genus of Central and South American semiaquatic wandering spiders first described by Philipp Bertkau in 1880. Originally placed with the nursery web spiders, it was moved to the Ctenidae in 1967. The genus name is derived in part from Ancient Greek "" ('' ancylo-''), meaning "crooked, bent". These spiders live near ponds, lakes, rivers and other freshwater habitats, and can walk on water like water striders due to fine air-trapping hairs on the tips of their legs. They can also dive under the surface, and can stay underwater for over an hour by using the air trapped in hairs surrounding their book lungs. They will consume anything from insects to small lizards and, occasionally, small fish. Description Members of ''Ancylometes'' are among the largest araneomorph spiders, with a typical body length of . They are sometimes referred to as "giant fishing spiders" to distinguish them from ''Dolomedes'', a genus of smaller spiders also called "fishing spiders". ...

Dendropsophus Melanargyreus
''Dendropsophus melanargyreus'' is a species of mid-size tree frog in the family Hylidae. It is found in Bolivia, Brazil, French Guiana, Paraguay, and Suriname Suriname (; srn, Sranankondre or ), officially the Republic of Suriname ( nl, Republiek Suriname , srn, Ripolik fu Sranan), is a country on the northeastern Atlantic coast of South America. It is bordered by the Atlantic Ocean to the north .... Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and intermittent freshwater marshes. It is threatened by habitat loss. ''D. melanargyreus'' is characterized by having dark blotches on its back, ranging in color from gray and tan to dark yellows and browns. It normally possesses a reddish brown X that descends from the upper eyelids and descends to the lower back. The underside is usually white and pale yellow in coloration with speckled black blotches.

Bulletin of the American Museum of Natural History, 299, 1–262 formerly ''Epipedobates trivittatus'', is a species of frog in the family Dendrobatidae commonly known as the three-striped poison frog. It is found in Bolivia, Brazil, Colombia, Guyana, Peru, Suriname, Venezuela, possibly Ecuador, and possibly French Guiana. Its natural habitats are subtropical or tropical moist lowland forest floors and intermittent freshwater marshes. ''A. trivittata'' is diurnal and terrestrial. Its distinctive features include its large size (up to 50 mm), granular skin, lack of webbing between digits, and distinctive striped markings. The colour of these markings varies; typically the stripes are green, but yellow and orange specimens occur, as well. It lays terrestrial eggs, which are hidden in clutches under leaves. The ...
