Caligus musaicus is a sea louse species [1] that parasitises the European flounder (Platichthys flesus); it was discovered off Portugal. [2]
Flounders are a group of flatfish species. They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries.
A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward.
Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side. A small number of species in Pleuronectidae can also have their eyes on the left side, notably the members of the genus Platichthys.
The Bidasoa is a river in the Basque Country of northern Spain and southern France that runs largely south to north. Named as such downstream of the village of Oronoz-Mugairi in the province of Navarre, the river actually results from the merger of several streams near the village Erratzu, with the stream Baztan that rises at the north-eastern side of the mount Autza being considered the source of the Bidasoa. It joins the Cantabrian Sea between the towns of Hendaye and Hondarribia.
Fernando Manuel Fernandes da Costa Santos is a Portuguese professional football manager and former player who played as a defender. He is the manager of the Poland national team.
The European flounder is a flatfish of European coastal waters from the White Sea in the north to the Mediterranean and the Black Sea in the south. It has been introduced into the United States and Canada accidentally through transport in ballast water. It is caught and used for human consumption.
Platichthys is a genus of flatfish native to the North Pacific and North Atlantic oceans. Despite being in the family Pleuronectidae, all three species in the genus Platichthys are often "lefteyed", i.e. they lie on the sea bottom on their right side, with both eyes on the left side.
The Pacific sand sole, also known as simply sand sole, is a flatfish species inhabiting the northeastern Pacific waters where it lives on sandy bottoms. The only species in the genus, Psettichthys, it ranges from the Bering Sea to Northern California.
The blackish stingray, Hemitrygon navarrae, is a little-known species of stingray in the family Dasyatidae, found in the northwestern Pacific Ocean off the coasts of mainland China and Taiwan. This species reaches 38 cm (15 in) across and has a chocolate brown, diamond-shaped pectoral fin disc nearly as long as wide. Its whip-like tail bears three large tubercles in front of the stinging spine, as well as both dorsal and ventral fin folds with the ventral fold half as long as the disc. Caught as bycatch in bottom trawls, the blackish stingray is frequently marketed as food in China.
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:
The River Allen, or St Allen River, to the north of Truro is one of two watercourses in Cornwall which share this name.
The Fortress of Cacela (Portuguese: Fortaleza de Cacela also known as Fort Cavaleiros de Santiago (Portuguese: Fortaleza dos Cavaleiros de Santiago is a fortress in the civil parish of Vila Nova de Cacela, municipality of Vila Real de Santo António, in the southeastern Portuguese district of Faro.
Acanthochondria limandae is a species of copepods in the genus Acanthochondria. They are host-specific ectoparasites of two species of flatfish: the common dab and the European flounder. They attach themselves to the bases of the gill arches of their hosts. They can infest as much as 2 to 30% of fish in a given population.
Ivan Ricardo Neves Abreu Cavaleiro is a Portuguese professional footballer who plays for Ligue 1 club Lille. Mainly a winger, he can also play as a forward.
Hediste diversicolor, commonly known as a ragworm, is a polychaete worm in the family Nereidae. It lives in a burrow in the sand or mud of beaches and estuaries in intertidal zones in the north Atlantic. This species is used in research but its classification is in dispute and in the literature it is often classified as Nereis diversicolor. Its specific name "diversicolor" refers to the fact that its colour changes from brown to green as the breeding season approaches.
1-Hydroxyphenanthrene is a phenanthrol and a human metabolite of phenanthrene that can be detected in urine of persons exposed to PAHs.
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.
Susana Santos Silva is a Portuguese jazz and free improvisation musician.
The Baltic flounder is a species of flatfish endemic to the Baltic Sea, where it is the only known endemic fish species.
Acanthochondria cornuta is a species of parasitic copepod from the northeast Atlantic Ocean, and the type species of the genus Acanthochondria. It infects the gills of several species of flatfish, particularly the European flounder. Copepodids and immature females infect the holobranch of the host, while adult females prefer the pseudobranch and the internal wall, suggesting they migrate upstream in the gills of the host as they mature.
