(a.) Belonging to the order of fishes having spinose fins, as the perch.
(n.) A spiny-finned fish.
Example Sentences:
(1) The hypothesis that the posterior pretectal nucleus in these species is homologous to both the pars intermedius of the superficial pretectal nucleus and nucleus glomerulosus in acanthopterygians is supported by multiple similarities in relative position and cytoarchitecture.
(2) The presence of glomeruli in the posterior pretectal nucleus and nucleus glomerulosus in esocids and acanthopterygians, respectively, and the presence of two nuclei, the pars intermedius and nucleus glomerulosus, in acanthopterygians, as opposed to one nucleus, the posterior pretectal nucleus, are apomorphies.
(3) Nevertheless, the position of Brotula multibarbata showed that this fish is an evolved acanthopterygian.
Superorder
Definition:
(n.) A group intermediate in importance between an order and a subclass.
Example Sentences:
(1) Chromatin of 14 species of fish referring to nine families of the percoid fish superorder includes protamines similar to salmin, a typical protamine of salmon.
(2) The usage as well as some of the known family chemical characteristics of Xhosa and Zulu traditional medicinal plants belonging to various families of the superorder Liliiflorae are related to some of the clinical effects of Xhosa medicine observed by Solleder in 1972.
(3) The superorder Archonta has been hypothesized to include primates, tree shrews, bats, and flying lemurs as descendants of a common ancestor.
(4) Also in congruence with other recent molecular evidence, IRBP sequences do not support the view of a superorder Archonta that includes Chiroptera along with Dermoptera (flying lemur), Scandentia (tree shrew), and Primates.
(5) The hemoglobin of Trichechus inunguis is compared with those of Elephas maximus, Loxodonta africana, and Procavia habessinica and the monophyletic origin of the superorder Paenungulata is discussed.
(6) The relationships between the squalomorphs and other superorders of sharks and the relationships between the different orders within the squalomorphs are a matter of debate.
(7) This is particularly true for the superorder Squalomorphii.
(8) Here, we report a molecular phylogeny for a little known member of this superorder, the genus Echinorhinus.
(9) Alpha = 0.56 for the class of cartilaginous fishes, and for the superorder of sharks and skates alpha = 0.54 and 0.61, accordingly.
(10) Sequence comparison of the northern pike growth hormone gene to other known growth hormone genes revealed similarities closest to other members of the superorder Protacanthopterygii, which includes the Salmonidae family (i.e., salmon and trout).
(11) The superorder Elopomorpha (orders Anguilliformes, Elopiformes and Notacanthiformes) is characterized by the presence of a unique larval stage termed the leptocephalus.
(12) Chromatin of three species from squid superorder referring to Cephalopoda includes gametones -- proteins differing from histones and protamines both in the electrophoretic mobility and amino acidic composition (75% mol.
(13) Hesslerella shermani is described as the oldest representative of the crustacean superorder Peracarida, order Isopoda, suborder Phreatoicidea.
(14) Results obtained by parsimony analysis provide evidence for this grouping--and thus support for the genealogical validity of Simpson's superorder Paenungulata, which contains as the extant orders Proboscidea, Sirenia, and Hyracoidea.
