What's the difference between flatfish and roundfish?
(n.) Any fish of the family Pleuronectidae; esp., the winter flounder (Pleuronectes Americanus). The flatfishes have the body flattened, swim on the side, and have eyes on one side, as the flounder, turbot, and halibut. See Flounder.
(1) These unique connections provide the necessary and sufficient connectivity to adapt the flatfish's eye movement system to the animals' postmetamorphic existence.
(2) The geographic distribution pattern points to the existence of areas around the globe in which flatfish or eels are able to develop skin papillomas.
(3) Intracellular staining of central neurons with horseradish peroxidase revealed that in postmetamorphic flatfish second-order horizontal canal neurons contact vertical eye muscle motoneuron pools on both sides of the brain via pathways that are absent in all other vertebrates studied.
(4) The 1-butanol adduct enhancement version of the 32P-postlabeling assay was used to measure the levels of hepatic DNA adducts in the marine flatfish, English sole (Parophrys vetulus), sampled from the Duwamish Waterway and Eagle Harbor, Puget Sound, WA, where they are exposed to high concentrations of sediment-associated chemical contaminants and exhibit an elevated prevalence of hepatic neoplasms.
(5) Flatfish, mainly in the form of plaice, and crustacea were found to be the main source of organic arsenic compounds.
(6) The opposite is found for lymphocystis, which is common among flatfish species of the Atlantic shores of Europe and North America.
(7) Amphistium Amphistium is a 50m-year-old relative of the flatfish.
(8) During their metamorphosis, the animals undergo a 90 degrees tilt to one side or the other to become the bottom-adapted adult flatfish.
(9) We studied the allergenic significance of the fish species considered most representative because of their greater consumption in our environment (flatfishes: Pleuronectiformes such as sole, whiff, and witch; Gadiformes such as hake; and Scombriformes such as albacore) or because of the results of previous studies of Gadiformes such as cod.
(10) Outside these areas of "potential skin papilloma risk," flatfish and eel populations are not afflicted with papillomas even if they inhabit estuaries or rivers with a high man-made or naturally-occurring pollution.
(11) Fish lymphocystis disease viruses (FLDV) were isolated directly from lymphocystis disease lesions of various flatfish species and further purified.
(12) The results of both laboratory and field studies show that sediment-associated PAHs are biologically available to both flatfish species, and that both species accumulate similar levels of PAHs.
(13) The peripheral and central oculomotor organization of the adult flatfish presents no morphological substrates that suffice to explain adaptive changes in its vestibuloocular reflex system.
(14) These species and the flatfishes Platichthys flesus (Linnaeus) and Limanda limanda (Linnaeus) were laboratory infected.
(15) Pardaxin, an active principle of the repellent secretion of the Red Sea flatfish, Pardachirus marmoratus, elicited severe struggling, mouth paralysis, and transient increase in urea leakage from the gills only when administered to the medium bathing the shark's pharyngeal cavity and gills.
(16) In a marine flatfish halibut, (Hippoglossus hippoglossus), we have found a more specialized hatching process.
(17) While modern flatfish, like flounder, plaice and sole, have both eyes on one side of the head, the shift in eye position is incomplete in Amphistium.
(18) Mechanical or electrical stunning is compulsory except for eel and flatfish.
(19) The effects of the two toxic proteins Pardaxin I and II isolated from the gland secretion of the flatfish Pardachirus marmoratus on frog neuromuscular transmission have been investigated and compared to those of the gland secretion.
(20) A comprehensive description of the histopathologic characteristics of a spectrum of idiopathic lesions in feral English sole (Parophrys vetulus), a bottom-dwelling flatfish, from Puget Sound, Washington State, is presented.
(n.) Any ordinary market fish, exclusive of flounders, sole, halibut, and other flatfishes.
(n.) A lake whitefish (Coregonus quadrilateralis), less compressed than the common species. It is very abundant in British America and Alaska.
