Robert Thomson Leiper
Robert Thomson Leiper (17 April 1881 – 21 May 1969) FRS CMG was a British parasitologist and helminthologist. Early life and education Leiper was born on 17 April 1881 in Witch Road, Kilmarnock, Scotland; the eldest of three children of John Leiper (died 1895), tailor, and his wife, Jessie Aird. The family moved to England shortly after he was born. He was educated at Warwick School, spending time at the Warwick Technical College to further his studies in science. He spent a year at Mason Science College (which later became the University of Birmingham), matriculating in physics, mathematics, English and Latin. He then entered the University of Glasgow to study medicine, at which he excelled, winning awards such as the John Hunter Medal and the Senior Arnott Prize in the field; graduating in 1904. Career From an early age Leiper was devoted to helminthology, the study of parasitic flatworms; while still an undergraduate, at the age of 21, he discovered an undocumented turbe ...

Digenea
Digenea (Gr. ''Dis'' – double, ''Genos'' – race) is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms (known as ''flukes'') with a syncytial tegument and, usually, two suckers, one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6,000 species have been described to date. Morphology Key features Characteristic features of the Digenea include a syncytial tegument; that is, a tegument where the junctions between cells are broken down and a single continuous cytoplasm surrounds the entire animal. A similar tegument is found in other members of the Neodermata; a group of platyhelminths comprising the Digenea, Aspidogastrea, Monogenea and Cestoda. Digeneans possess a vermifo ...

Trematode
Trematoda is a class of flatworms known as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five traditional vertebrate classes: mammals, birds, amphibians, reptiles, and fish. Etymology Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. Taxonomy There are 18,000 to 24,000 known species of trematodes, divided into two subclasses — the Aspidogastrea and the Digenea. Aspidogastrea is the smaller subclass, comprising 61 species. These flukes mainly infect bivalves and bony fishes.https://www.biotaxa.org/Zootaxa/article/view/zootaxa.3918.3.2 Digenea — which comprise the majority of trematodes — ...

Indoplanorbis Exustus
''Indoplanorbis'' is a genus of air-breathing freshwater snail. Its Monotypic taxon, only member species is ''Indoplanorbis exustus'', an aquatic animal, aquatic pulmonate gastropod mollusk in the family (biology), family Planorbidae, the sheep, ram's horn snails. The species is widely distributed across the tropics. It serves as an important intermediate host for several trematode parasites. The invasive species, invasive nature and ecological tolerance of ''Indoplanorbis exustus'' add to its importance in veterinary and medical science. Taxonomy ''Indoplanorbis exustus'' is the only known species in the genus ''Indoplanorbis''. In spite of its long history and wide geographical range, it is thought that ''Indoplanorbis'' includes only a single species. However phylogeography research by Liu et al. (2010) revealed the phylogenetic depth of divergences between the Indian clades and Southeast Asian clades, together with habitat and parasitological differences suggest that ''Indopl ...

These snails simultaneously have a gill and a lung as functional respiratory structures, wh .... The species is found in Southeastern Asia and Central America. However, it has been taken from its native habitat to be used as a food delicacy, control of weeds in freshwater, a component in home aquariums, and as a vector for parasitic larva in the freshwater. This has made it very difficult to determine ''Pila scutata's'' true native range. References Ampullariidae {{Improve categories, date=February 2022 ...

Animals Described In 1943
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the ec ...
