Cichlidogyrus Nageus
''Cichlidogyrus'' is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is '' Cichlidogyrus arthracanthus'' Paperna, 1960, by original designation. All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae. Species of ''Cichlidogyrus'' are parasitic in many clichlid species in the Lake Tanganyika; a recent study (2016) has shown that species which are parasite on deep-water fish show reduced parasite-host specificity in comparison to species from littoral waters, probably an adaptation to low host availability. According to Antoine Pariselle and Louis Euzet, 71 species of ''Cichlidogyrus'' were known in 2009 - new species have been described since. Nikol Kmentová, Milan Gelnar, Stephan Koblmüller and Maarten P.M. Vanhove estimated that the number of species was more than 100 in 2016 and Chahrazed Rahmouni, Maarten P. M.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, 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 Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alien Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlidogyrus Philander
''Cichlidogyrus philander'' is a species of Monopisthocotylean Monogenean, in the family Ancyrocephalidae. It is ectoparasitic on the gills of the fish ''Pseudocrenilabrus philander''. The species has been described by Laurence Douëllou in 1993 from fish collected in Lake Kariba, Zimbabwe. A complete and detailed redescription of the species, using scanning electron microscopy in addition to traditional microscopy, has been done by Igeh, Dos Santos & Avenant-Oldewage in 2017. These authors used specimens collected from the same fish species, from Padda Dam, Gauteng, South Africa. Genetic characters derived from the 28S rDNA, the COI mitochondrial DNA and ITS1 rDNA regions distinguish ''C. philander'' from all other ''Cichlidogyrus'' sequenced species. Morphology ''Cichlidogyrus philander'' is characterised by a penis with a sharp, curved, lateral termination, an accessory piece with a hook-like extremity that may appear forked terminally, and lack of a visible vagina.
