Otto Franz Von Möllendorff
Otto Franz von Möllendorff (24 December 1848 – 17 August 1903) was a German scientist, a malacologist. In 1894, Jose Rizal sent (from Dapitan) to Möllendorff (who was in Manila at that time) specimens of Tonnidae, large sea snails known as tun shells together with some specimens of a species of small freshwater snails stored in glass vials. The species of small snails was later named ''Oncomelania hupensis, Oncomelania quadrasi'' by Möllendorff in 1895 in honour of Don José Florencio Quadras, a Spanish malacologist who was also based in Manila at that time.Davis GM (1979).

Otto Franz Von Mollendorff
Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants ''Audo'', ''Odo'', ''Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded from the 7th century ( Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was ''auda-'' (as in e.g. '' Audaþius''), the Anglo-Saxon form was ''ead-'' (as in e.g. ''Eadmund''), and the Old Norse form was '' auð-''. The given name Otis arose from an English surname, which was in turn derived from ''Ode'', a variant form of ''Odo, Otto''. Due to Otto von Bismarck, the given name ''Otto'' was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dapitan
Dapitan, officially the City of Dapitan ( ceb, Dakbayan sa Dapitan; Subanon: ''Gembagel G'benwa Dapitan/Bagbenwa Dapitan cbk, Ciudad de Dapitan''), is a 3rd class component city in the province of Zamboanga del Norte, Philippines. According to the 2020 census, it has a population of 85,202 people. It is historically significant as the place where José Rizal was exiled by the Spanish colonial authorities for his threat to start revolutionary activities. He is considered a national hero, and this is known as the "Shrine City in the Philippines." It is also often considered the capital of Mindanao Island. The city is also home to Gloria's Fantasyland, the first amusement park in Mindanao. History The earliest settlers of Dapitan were the Subanens, a nomadic tribe of Austronesian stock known to have settled and lived along the banks of the river or “suba” out of which their present-day tribal identity originated. Early cartographers of the Philippines showed Dapitan's loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manila
Manila ( , ; fil, Maynila, ), officially the City of Manila ( fil, Lungsod ng Maynila, ), is the capital of the Philippines, and its second-most populous city. It is highly urbanized and, as of 2019, was the world's most densely populated city proper. Manila is considered to be a global city and rated as an Alpha – City by Globalization and World Cities Research Network (GaWC). It was the first chartered city in the country, designated as such by the Philippine Commission Act 183 of July 31, 1901. It became autonomous with the passage of Republic Act No. 409, "The Revised Charter of the City of Manila", on June 18, 1949. Manila is considered to be part of the world's original set of global cities because its commercial networks were the first to extend across the Pacific Ocean and connect Asia with the Spanish Americas through the galleon trade; when this was accomplished, it marked the first time in world history that an uninterrupted chain of trade routes circling ...

Tonnidae
The Tonnidae are a family (biology), family of medium-sized to very large sea snails, known as the tun shells. These are marine invertebrates, marine gastropod molluscs in the clade Littorinimorpha. The name ''tun'' refers to the snails' shell shape, which resembles wine casks known as "tuns". While thin, the shells are also strong and lack operculum (gastropod), opercula. They are found in all tropical seas, where they inhabit sandy areas. During the day, they bury themselves in the substrate (biology), substrate, emerging at night to feed on echinoderms (especially sea cucumbers), Crustacean, crustaceans, and bivalves. Some larger species also capture fish, using their expandable probosces to swallow them whole. Females lay rows of eggs that become free-swimming larvae for several months before settling to the bottom. Taxonomy In 2005, these subfamilies were recognized in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of Bouchet & Rocroi: *Cassinae Latreille ...

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] |
Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Oncomelania Hupensis
''Oncomelania hupensis'' is a species of very small tropical freshwater snail, an aquatic gastropod mollusk in the family Pomatiopsidae. Distribution ''Oncomelania hupensis'' has been found in China, Taiwan, and also in Japan, the Philippines, and on the Indonesian island of Sulawesi. Description Over the past a few decades, the taxonomy of ''Oncomelania hupensis'' has been a dispute due to the variation in morphological characters such as shell sculpture, operculum etc. Phenotypically, ''Oncomelania hupensis'' can be separated into ribbed- and smooth- shelled morphotypes. In China, the typical morphotype of ''Oncomelania hupensis'' is ribbed-shelled, and its distribution is restricted to Yangtze River basin. Smooth-shelled snails are also distributed in mainland China, but are considered the same species and subspecies of ''Oncomelania hupensis''. ''Oncomelania hupensis'' reported in other Far East countries are smooth-shelled, and have been considered either as su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academy Of Natural Sciences Of Philadelphia
The Academy of Natural Sciences of Drexel University, formerly the Academy of Natural Sciences of Philadelphia, is the oldest natural science research institution and museum in the Americas. It was founded in 1812, by many of the leading naturalists of the young American republic with an expressed mission of "the encouragement and cultivation of the sciences". It has sponsored expeditions, conducted original environmental and systematics research, and amassed natural history collections containing more than 17 million specimens. The Academy also organizes public exhibits and educational programs for both schools and the general public. History During the first decades of the United States, Philadelphia was the cultural capital and one of the country's commercial centers. Two of the city's institutions, the Library Company and the American Philosophical Society, were centers of enlightened thought and scientific inquiry.

Rat Snake
Rat snakes are members – along with kingsnakes, milk snakes, vine snakes and indigo snakes – of the subfamily Colubrinae of the family Colubridae. They are medium to large constrictors and are found throughout much of the Northern Hemisphere. They feed primarily on rodents. Many species make attractive and docile pets and one, the corn snake, is one of the most popular reptile pets in the world. As with all snakes, they can be defensive when approached too closely, handled, or restrained. However, rat snake bites are not dangerous to humans. Like nearly all colubrids, rat snakes pose no threat to humans. Rat snakes were long believed to be completely nonvenomous, but recent studies have shown that some Old World species do possess small amounts of venom, though the amount is negligible relative to humans. Previously, most rat snakes were assigned to the genus ''Elaphe'', but many have been since renamed following mitochondrial DNA analysis performed in 2002. For the p ...

Elaphe Moellendorffi
''Elaphe moellendorffi'', commonly called the flower snake or Moellendorf's icrat snake, is a species of snake in the family Colubridae. The species is endemic to southeastern Asia. Etymology The specific name, ''moellendorffi'', is in honor of German malacologist Otto Franz von Möllendorf. Geographic range ''E. moellendorffi'' is found in China (Guangdong, Guangxi) and Vietnam ( Hòa Bình). It may possibly also occur in Laos. Description ''E. moellendorffi'' is a large snake. Adults may attain a total length (including tail) of .Boulenger (1894). Reproduction ''E. moellendorffi'' is oviparous Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and .... References Further reading * Boettger O (1886).
