Craugastor Fitzingeri
''Craugastor fitzingeri'' is a species of frog in the family Craugastoridae. It is found in northwestern Colombia, Panama, Costa Rica, eastern Nicaragua, and northeastern Honduras. The specific name ''fitzingeri'' honors Leopold Fitzinger Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhis ..., an Austrian zoologist. Common name Fitzinger's robber frog has been coined for this species. Description Adult males measure and adult females in snout–vent length. The snout is subacuminate in dorsal view. The tympanum is prominent. The fingers and the toes bear discs; the toes are moderately webbed. Skin typically bears warts and ridges. The dorsal coloration varies from gray-brown to brown to orange-brown. Some individuals have a wide, light middorsal stripe. Most individuals have only ...

Eduard Oscar Schmidt
Eduard Oscar Schmidt (21 February 1823, in Torgau – 17 January 1886, in Kappelrodeck) was a German zoologist and phycologist. Biography He initially studied mathematics and science at Halle, then continued his education in Berlin, where he came under the influence of Christian Gottfried Ehrenberg and Johannes Peter Müller. In 1847 he received his habilitation at the University of Jena, becoming an associate professor during the following year. In 1855 was he appointed professor of zoology at the University of Cracow. Later he taught classes at the Universities of Graz (from 1857) and Strasbourg (from 1872). Schmidt was an early proponent of Darwinian evolutionary thought. He is remembered for his research of Porifera (sponges), particularly species from the Adriatic Sea. Schmidt also made contributions in the field of phycology. As far back as 1862 Oscar Schmidt showed that "cuttings" of sponges will attach themselves and grow. This idea was followed through in the exp ...

Sexual Selection In Amphibians
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour *Animal sexual behaviour **Copulation (zoology) **Human sexual activity **Non-penetrative sex, or sexual outercourse **Sex drive, a person's overall sexual drive or desire for sexual activity ** Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species * Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization ** Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainment ...

Amphibians Described In 1857
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 decl ...

Amphibians Of Panama
This is a list of amphibians found in Panama. 205 amphibian species have been registered in Panama, which are grouped in 3 orders: Caecilians (Gymnophiona), Salamanders (Caudata) and Frogs and Toads (Anura). This list is derived from the database listing of AmphibiaWeb.AmphibiaWeb 2012 25 species are critically endangered(CR), 16 species are endangered (EN) and 6 species are vulnerable (VU). One species has recently (September 2016) gone extinct with the last individual in captivity dying, and with not a single specimen seen nor heard in the wild for over a decade. Several other species might also be extinct with no specimen found for decades. The following tags are used to highlight specific species' conservation status as assessed by the IUCN: Caecilians (Gymnophiona) Caeciliidae Order: Gymnophiona. Family: Caeciliidae *'' Caecilia isthmica'' (DD) *'' Caecilia leucocephala'' (LC) *'' Caecilia nigricans'' (LC) *'' Caecilia tentaculata'' (LC) *'' Caecilia volcani'' (DD) *'' ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Frog
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] |
Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...
