Pontella is a marine copepod genus in the family Pontellidae. It is an organism that bears three lenses in the eye. The outer has a parabolic surface, countering the effects of spherical aberration while allowing a sharp image to be formed. [1]
Pontella includes the following species: [2]
Henri Milne-Edwards was an eminent French zoologist.
Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes. Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts. Most are marine, but a few live in fresh water. There are 40 recognised families:
Calanidae is the largest taxonomic family of calanoid copepods. It includes the genus Calanus, which may be the most abundant metazoan genus on Earth.
Cyclops is one of the most common genera of freshwater copepods, comprising over 400 species. Together with other similar-sized non-copepod fresh-water crustaceans, especially cladocera, they are commonly called water fleas. The name Cyclops comes from the Cyclops of Greek mythology, as they have a single large eye; in Cyclops, the eye may be either red or black.
Diaptomus is a genus of copepods with a single eye spot. It is superficially similar in size and appearance to Cyclops. However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in Cyclops. It is a copepod of larger freshwater ponds, lakes and still waters.
Sapphirina, whose members are commonly known as sea sapphires, is a genus of parasitic copepods in the family Sapphirinidae.
Acartia is a genus of marine calanoid copepods. They are epipelagic, estuarine, zooplanktonic found throughout the oceans of the world, primarily in temperate regions.
Caligus is a genus of sea lice in the family Caligidae. The species are parasites of marine fishes and could be vectors of viruses. As of 2017, the World Register of Marine Species includes the following species:
Pontellidae is a family of copepods in the order Calanoida, containing the following genera:
Copilia is a genus of copepods in the family Sapphirinidae. The eyes in members of this genus have two lenses, arranged like those in a telescope.
Euaugaptilus is a genus of copepods. The genus contains bioluminescent species.
Lepeophtheirus is a genus of sea louse. The best-known species is L. salmonis, the salmon louse. Other species include L. pectoralis, which uses flatfish as its host, particularly the European flounder, and is also the type species of the genus Lepeophtheirus.
Centropages is a genus of copepods in the family Centropagidae with 34 known marine species.
Neocalanus is a genus of marine copepods. They are a dominant component of the open water ecosystems of the northern Pacific Ocean. Neocalanus are large copepods, reaching body lengths of more than 8 mm (0.31 in) in Neocalanus plumchrus.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Oithona is a planktonic crustacean genus found in marine, brackish, fresh water environments. Oithona has been described as the most ubiquitous and abundant copepod in the world's oceans. It was first described by Baird in 1843 using the species Oithona plumifera as taxon type.
Aetideidae is a family of copepods belonging to the order Calanoida.
Candacia is a genus of copepods in the order Calanoida. It is the only genus in the monotypic family Candaciidae.
