Prasinohaema
''Prasinohaema'' ( Greek: "green blood") is a genus of skinks characterized by having green blood. This condition is caused by an excess buildup of the bile pigment biliverdin. ''Prasinohaema'' species have plasma biliverdin concentrations approximately 1.5-30 times greater than fish species with green blood plasma and 40 times greater than humans with green jaundice. The benefit provided by the high pigment concentration is unknown, but one possibility is that it protects against malaria. Geographic range Species in the genus ''Prasinohaema'' are endemic to New Guinea and the Solomon Islands.

Prasinohaema Virens
The green-blooded skink (''Prasinohaema virens''), sometimes (ambiguously) known as green tree skink, is a scincid lizard species native to Papua New Guinea and the Solomon Islands. This small and arboreal lizard is common, but poorly known.Molecular, morphological, and physiological evolution in South Pacific scincid lizards. Austin, Christopher Cowell, Ph.D., The University of Texas at Austin, 1995, 213 pages; AAT 9603793 Physiology The skink has developed setae on its toe pads (or digit pads) for climbing analogous to those of geckos and anoles, but the trait is believed to have evolved independently to these groups, so is an example of convergent evolution. With regards to the trait, other species in the genus, '' P. flavipes'' and '' P. prehensicauda'', have the primitive character, and lack the setae. Other skinks within the genus ''Lipinia'' have also evolved toe pad setae, and within the skink family, four morphologically distinct adhesive microstructures have evolved, p ...

Skink
Skinks are a type of lizard belonging to the family (biology), family Scincidae, a family in the Taxonomic rank, infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Etymology The word ''skink'', which entered the English language around 1580–1590, comes from classical Greek and Latin , names that referred to various specific lizards. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the Tribolonotus gracilis, red-eyed crocodile skink have a head that is ve ...

Richard Semon
Richard Wolfgang Semon (22 August 1859, in Berlin – 27 December 1918, in Munich) was a German zoologist, explorer, evolutionary biologist and memory researcher who believed in the inheritance of acquired characteristics and applied this to social evolution. He is known for coining the terms '' engram'' and '' ecphory''. Australia Before taking up his appointment at the University of Jena, he spent three years travelling around Australia; and the Indonesian Archipelago and, as a consequence, he was one of a number of influential German-speaking residents such as Ludwig Becker, Hermann Beckler, William Blandowski, Amalie Dietrich, Wilhelm Haacke, Diedrich Henne, Gerard Krefft, Johann Luehmann, Johann Menge, Carl Mücke (a.k.a. Muecke), Ludwig Preiss, Carl Ludwig Christian Rümker (a.k.a. Ruemker), Moritz Richard Schomburgk, Karl Theodor Staiger, George Ulrich, Eugene von Guérard, Robert von Lendenfeld, Ferdinand von Mueller, Georg von Neumayer, and Carl Wilhel ...

Hampton Wildman Parker
Hampton Wildman Parker, CBE (5 July 1897 – 2 September 1968) was an English zoologist. Parker graduated from Cambridge in 1923 with degrees in botany, zoology, and chemistry. Within the same year, he joined the staff of the British Museum (Natural History Museum, London, Natural History Museum) and was later assigned Keeper of Zoology from 1947 to 1957. During his career, he wrote several works on snakes and frogs. Parker also discovered a new species of lizard on the Seychelles, which he described and named Vesey-Fitzgerald's burrowing skink (''Janetaescincus veseyfitzgeraldi'') after Entomology, entomologist Leslie Desmond Foster Vesey-Fitzgerald.

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). The most abundant cells are red blood cells. These contain hemoglobin, which facilitates oxygen transport by reversibly binding to it, increasing its solubility. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Blood is circulated around the body through blood vessels by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biliverdin
Biliverdin (from the Latin for green bile) is a green tetrapyrrolic bile pigment, and is a product of heme catabolism.Boron W, Boulpaep E. Medical Physiology: a cellular and molecular approach, 2005. 984–986. Elsevier Saunders, United States. It is the pigment responsible for a greenish color sometimes seen in bruises. Metabolism Biliverdin results from the breakdown of the heme moiety of hemoglobin in erythrocytes. Macrophages break down senescent erythrocytes and break the heme down into biliverdin along with hemosiderin, in which biliverdin normally Biliverdin reductase, rapidly reduces to free bilirubin. Biliverdin is seen briefly in some bruises as a green color. In bruises, its breakdown into bilirubin leads to a yellowish color. Role in disease Biliverdin has been found in excess in the blood of humans suffering from hepatic diseases. Jaundice is caused by the accumulation of biliverdin or bilirubin (or both) in the circulatory system and tissues. Jaundiced skin ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
