Squamodisc
Squamodiscs are epidermal structures, which are typical of and found only in certain monogeneans of the family Diplectanidae. There are, typically, two squamodiscs, one ventral and one dorsal, located on the haptor of the monogenean. Squamodiscs are usually made up of scales embedded in the epidermis, which appear from the outside as rodlets arranged in rows. According to the classical book of Bychowsky (1967), Bychowsky, B. E.

English translation by the American Institute of Biological Science, Washington. 509 pp. “the Diplectanidae] have special paired attaching formations lying above the disc and also partially on it, on the dorsal and ventral sides in the shape of small rounded convexities equipped with numerous ..thorn-shaped little hooks or thin thread-like plates located more or less in concentric rows ("squamodisc")".

Louis Euzet
Louis Euzet (27 July 1923 in Lézignan-Corbières, France – 24 September 2013 in Sète, France) was a French parasitologist. Education Louis Euzet was a high-school student in Narbonne, France, and a student of the University of Montpellier (in the then “''Faculté des Sciences''”). He obtained his bachelor's degree (''Licence'') in 1947. He prepared his doctoral thesis in the Station de Biologie Marine at Sète, under the direction of Paul Mathias and Jean-George Baer; the thesis, on tetraphyllidean cestodes, was accepted on 16 June 1956. Career Louis Euzet was a junior lecturer at the Station de Biologie Marine in Sète in 1947. He was appointed Professor in the recently created “''Collège Scientifique Universitaire''” at Perpignan in 1959. He moved in 1969 to the University of Montpellier, where he established his ''Laboratoire de Parasitologie Comparée'' (Laboratory of Comparative Parasitology). He retired in 1991, became an Emeritus Professor in 1992 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplectanidae
The Diplectanidae are a family of monopisthocotylean monogeneans. They are all parasitic on the gills of fish (marine or freshwater). Diplectanids are small animals, generally around 1 mm in length. As parasites, they can be extremely numerous, up to several thousand on an individual fish. History The family Diplectanidae was proposed by the Italian parasitologist Monticelli in 1903 (as subfamily Diplectaninae). The status of the family and its components was later examined by various authors, including Johnston & Tiegs (1922), Price (1937),Price, E. W. 1937: North American Monogenetic Trematodes. I. The superfamily Gyrodactyloidea ''Journal of the Washington Academy of Sciences'' 27, 146-164PDF Bychowsky (1957), Yamaguti (1963), and Oliver (1987). Morphology Diplectanids are diagnosed by the combination of these three characters: * Presence of accessory adhesive organs on dorsal and ventral part of the haptor, called squamodiscs when they are made up of rodlets and lame ...

Lamellodisc
Lamellodiscs are epidermal structures, which are typical of and found only in certain monogeneans of the family Diplectanidae. There are, typically, two lamellodiscs, one ventral and one dorsal, located on the haptor of the monogenean. Lamellodiscs are made up of concentric lamellae embedded in the epidermis. Lamellodiscs are considered as special type of squamodiscs, which are homologous structure found in many diplectanid monogeneans but formed of rows of rodlets instead of lamellae. Lamellodiscs are found in members of the diplectanid genera '' Lamellodiscus'' or ''Calydiscoides ''Calydiscoides'' is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
