Sauroplasma
Sauroplasma is a genus of parasites of the phylum Apicomplexa. Species in this genus have two hosts (a vertebrate and an invertebrate) in their life cycle: for species in this genus the vertebrate host are lizards. The vectors are not known but ticks have been suggested as possible hosts. The type species is ''Sauroplasma thomasi''. History This genus was described in 1938 by du Toit. Description To date this species has been described from erythrocytes only. The parasites are amoeboid but frequently adopt a ring shape. A vacuole is present and occasionally one or more pigment granules. Schizogony is absent. Binary fission or budding into two daughter cells occurs.

Piroplasmida
Piroplasmida is an order of parasites in the phylum Apicomplexa. They divide by binary fission and as sporozoan parasites they possess sexual and asexual phases (sexual reproduction occurs in the tick gut). They include the tick parasites ''Babesia'' and ''Theileria''. Description They are minute rounded or pyriform parasites found within erythrocytes, or other circulating or endothelial cells of vertebrates, where they reproduce by merogony. The trophozoite stage is separated from erythrocyte by a single membrane. This distinguishes them from other blood parasites that usually have at least two membranes. An apical complex with a polar ring and rhopteries occurs, but without a conoid and usually without associated pellicular microtubules. They lack flagella and do not form either oocysts or spores. The known vectors are ticks or leeches in which they undergo sporogony; sexual reproduction probably occurs in the vector. See also * Babesiosis Babesiosis or piroplasmos ...

Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the Three-domain system, three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard (archaea), Asgard archaea. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass (ecology), biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. The ...

Schizogony
Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. The fission may be ''binary fission'', in which a single organism produces two parts, or ''multiple fission'', in which a single entity produces multiple parts. Binary fission Organisms in the domains of Archaea and Bacteria reproduce with binary fission. This form of asexual reproduction and cell division is also used by some organelles within eukaryotic organisms (e.g., mitochondria). Binary fission results in the reproduction of a living prokaryotic cell (or organelle) by dividing the cell into two parts, each with the potential to grow to the size of the original. Fission of prokaryotes The single DNA molecule first replicates, then attaches each copy to a differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uroplatus Fimbriatus
The common flat-tail gecko (''Uroplatus fimbriatus'') is a gecko endemic to Madagascar. It is found in eastern Madagascar and on the islands Nosy Bohara and Nosy Mangabe. These geckos live in tropical rain forests. They reach a total length of 330 mm. Etymology The generic name, ''Uroplatus'', is a Latinization of two Greek words: "ourá" (οὐρά) meaning "tail" and "platys" (πλατύς) meaning "flat". Its specific name ''fimbriatus'' is the Latin word for "fringed" based upon the gecko's unique appearance of fringed skin. Description It is a large nocturnal gecko. Because the eyes are extremely sensitive to light, 350 times more sensitive than the human eye, the species is able to see in colors even at night. By day it plasters itself to a small tree trunk and rests head down. If disturbed it will raise its tail and head, open its mouth and scream. Threats Habitat destruction and deforestation in Madagascar is the primary threat to this animal's future as well as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclura Nubila
The Cuban rock iguana (''Cyclura nubila''), also known as the Cuban ground iguana or Cuban iguana, is a species of lizard of the iguana family. It is the second largest of the West Indian rock iguanas (genus ''Cyclura''), one of the most endangered groups of lizards. A herbivorous species with a thick tail and spiked jowls, it is one of the largest lizards in the Caribbean. The Cuban iguana is distributed throughout the mainland of Cuba and its surrounding islets with a feral population thriving on Isla Magueyes, Puerto Rico. A subspecies is found on the Cayman Islands of Little Cayman and Cayman Brac. Females guard their nest sites and one population nests in sites excavated by Cuban crocodiles. As a defence measure, the Cuban iguana often makes its home within or near prickly-pear cacti. The numbers of iguanas have been bolstered as a result of captive-breeding and other conservation programs. ''C. nubila'' has been used to study evolution and animal communication, and i ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclura Lewisi
The blue iguana (''Cyclura lewisi''), also known as the Grand Cayman ground iguana, Grand Cayman blue iguana or Cayman Island rock iguana, is an endangered species of lizard which is endemic to the island of Grand Cayman. It was previously considered to be a subspecies of the Cuban iguana, ''Cyclura nubila'', but in a 2004 article Frederic J. Burton reclassified it as a separate species because according to him the genetic differences discovered four years earlier between the different ''C. nubila'' populations warranted this interpretation. The blue iguana is one of the longest-living species of lizard (possibly up to 69 years). The preferred habitat for the blue iguana is rocky, sunlit, open areas in dry forests or near the shore, as the females must dig holes in the sand to lay eggs in June and July. A possible second clutch is laid in September. The blue iguana's herbivorous diet includes plants, fruits, and flowers. Its color is tan to gray with a bluish cast that is m ...

Grand Cayman
Grand Cayman is the largest of the three Cayman Islands and the location of the territory's capital, George Town. In relation to the other two Cayman Islands, it is approximately 75 miles (121 km) southwest of Little Cayman and 90 miles (145 km) southwest of Cayman Brac. Geography Grand Cayman encompasses 76% of the territory's entire land mass. The island is approximately long with its widest point being wide. The elevation ranges from sea level at the beaches to above sea level on the North Side's Mastic Trail. Unlike many other Caribbean islands, Grand Cayman is for the most part, flat. This allows for more space to build as the island’s population grows. Island districts Grand Cayman Island includes five of the six districts of the Cayman Islands: Bodden Town, East End, George Town, North Side and West Bay. *Bodden Town – Founded in the 1700s, Bodden Town district comprises the central part of Grand Cayman Island, between the George Town and Nort ...

Cyclura Collei
The Jamaican iguana (''Cyclura collei''), also known commonly as Colley's iguana, is a large species of lizard in the family Iguanidae. The species is endemic to Jamaica. It is critically endangered, even considered extinct between 1948 and 1990. Once found throughout Jamaica and on the offshore islets Great Goat Island and Little Goat Island, it is now confined to the forests of the Hellshire Hills. Etymology The specific name, ''collei'', is in honor of someone named Colley. John Edward Gray, who originally described this species in 1845, referred to it as "Colley's Iguana". Unfortunately, Gray did not further specify who Colley was. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Colley's Iguana ''Cyclura collei'' ", pp. 56-57).
