Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic, some are benthic, a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.
Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a class in superclass Multicrustacea. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
Churcher's College is an independent, fee-charging day school for girls and boys, founded in 1722. Churcher’s College is regarded as a leading private school in the south of England. The Senior School is in the market town of Petersfield, Hampshire with the Junior School and Nursery in nearby Liphook. It is a member of the Headmasters' and Headmistresses' Conference (HMC).
Waldo LaSalle Schmitt was an American biologist born in Washington, D.C. He received his Ph.D. from George Washington University in 1922. In 1948, he received an honorary Doctor of Science degree from the University of Southern California. Schmitt's primary field of zoological investigation was carcinology, with special emphasis on the decapod crustaceans. His bibliography consists of more than seventy titles.
The family Argulidae, whose members are commonly known as carp lice or fish lice, are parasitic crustaceans in the class Ichthyostraca. It is the only family in the monotypic subclass Branchiura and the order Arguloida, although a second family, Dipteropeltidae, has been proposed. Although they are thought to be primitive forms, they have no fossil record.
Cancer is a genus of marine crabs in the family Cancridae. It includes eight extant species and three extinct species, including familiar crabs of the littoral zone, such as the European edible crab, the Jonah crab and the red rock crab. It is thought to have evolved from related genera in the Pacific Ocean in the Miocene.
The Cyclopoida are an order of small crustaceans from the subclass Copepoda. Like many other copepods, members of Cyclopoida are small, planktonic animals living both in the sea and in freshwater habitats. They are capable of rapid movement. Their larval development is metamorphic, and the embryos are carried in paired or single sacs attached to first abdominal somite.
The World Association of Copepodologists (WAC) is a non-profit organization created to promote research on copepods by facilitating communication among interested specialists.
Poecilostomatoida is a suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida.
Bomolochidae is a family of copepods parasitic on marine fishes. Most species parasitize the gills of fish, but some species live in the nostrils or on the eyes of their hosts. The family contains just over 150 species from the following genera:
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults, more-so than where the larvae are planktonic, and thereby easily caught.
Lernaeocera branchialis, sometimes called cod worm, is a parasite of marine fish, found mainly in the North Atlantic. It is a marine copepod which starts life as a small pelagic crustacean larva. It is among the largest of copepods, ranging in size from 2 to 3 millimetres when it matures as a copepodid larva to more than 40 mm as a sessile adult.
Hirsutiidae is a family of crustaceans, classified either as a separate order, Bochusacea, or as part of a wider Mictacea. It comprises five species in three genera:
Alejandro "Alex" Kacelnik, FRS is an Argentine-British zoologist, professor of behavioural ecology at Oxford University and E.P. Abraham Fellow of Pembroke College, Oxford. Kacelnik heads the Behavioural Ecology Research Group at Oxford. The author of more than 200 peer reviewed publications, his research focuses on the evolution of behaviour and mathematical modelling. His work uses an interdisciplinary approach, combining data and methods from zoology, psychology and economic theory. In 2011 Kacelnik was honoured by the Comparative Cognition Society for his contributions to the field of animal cognition. He has also received the Cogito Prize for interdisciplinary research linking the natural and social sciences, shared with Professor Ernst Fehr of the University of Zurich, the de Robertis Medal of the Argentinian Society of Neurosciences, and the Raíces ("Roots") Prize for contributions to international collaborations between Argentinian and other scientists.
Crustaceans are invertebrate animals of the subphylum Crustacea, a large, diverse group of mainly aquatic arthropods including decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans.
MarBEF Data System was a project of the European Union's Network of Excellence which served as a platform to integrate and disseminate knowledge and expertise on marine biodiversity, with informative links to researchers, industry, stakeholders and the general public. The program was funded by the EU and formally ended in 2009. The data system's online Register of Resources (RoR) includes the details of over 1,000 European marine biology experts and their affiliated institutions and publications.
Lepeophtheirus pectoralis is a species of parasitic copepod from the northeast Atlantic Ocean, and the type species of the genus Lepeophtheirus. It is a parasite of flatfish, with the European flounder, the plaice, and the dab as the most frequent hosts. It feeds on the mucus, skin, and blood of the fish, with egg-producing females infecting the pectoral and pelvic fins of the host, while immature individuals and males are found on the rest of the body.
Mildred Stratton Wilson was an American zoologist, whose work on copepods was awarded a Guggenheim Fellowship in 1955.
Cardiodectes bellottii is a species of copepods in the family Pennellidae. It is a parasite of fish. It is found in the Atlantic and Pacific Oceans as well as the Mediterranean Sea; specimens from the Pacific were formerly treated as a separate species, Cardiodectes medusaeus.
