What's the difference between elasmobranch and selachian?
Elasmobranch
Definition:
(a.) Of or pertaining to the Elasmobranchii.
(n.) One of the Elasmobranchii.
Example Sentences:

(2) If true, then brain damage from acidosis in elasmobranchs might evolve differently since glial reaction there to another necrotizing injury, exposure to extreme cold, is dissimilar from that seen in mammals.
(3) Intracellular fluids of marine elasmobranchs (sharks, skates and rays), holocephalans and the coelacanth contain urea at concentrations averaging 0.4m, high enough to significantly affect the structural and functional properties of many proteins.
(4) Fragments that consisted mainly of two polysaccharide chains joined by a short polypeptide bridge (doublets) were prepared from chondroitin sulphate-proteins of lamprey, sturgeon, elasmobranch and ox connective tissues after hydrolysis with trypsin and chymotrypsin.

(6) Attaining osmotic equilibrium with seawater by these fishes has thus involved the selective accumulation of certain nitrogenous metabolites that individually have significant effects on protein structure, but that have virtually no net effects on proteins when these solutes are present at elasmobranch physiological concentrations.
(7) In all the brain structures of higher elasmobranch fishes, fatty acid composition of gangliosides exhibits more progressive features of chemical organization as compared to that in homologous structures of lower elasmobranch fishes.
(8) We conclude that the pericardioperitoneal canal maintains negative pericardial pressure, which is a prerequisite in elasmobranch fishes and may serve to regulate pericardial pressure level to optimize cardiac function in relation to changes in cardiac size.
(9) The results indicate that this species has a much lower oxygen consumption than other elasmobranchs of comparable size.
(10) The in vivo activation and turnover rates of the sodium pump (Na+, K(+)-ATPase) were investigated in the electrocytes of the electric organ of the elasmobranch Narcine brasiliensis.
(11) Dogfish shark (Squalus acanthias) rectal gland cells swell massively when incubated in elasmobranch media in which Na+ was equivalently replaced by K+; this swelling was abolished when the impermeant gluconate replaced Cl-, while the cell depolarization was comparable in both media.
(12) The distribution of immunoreactive alpha-melanocyte-stimulating hormone (alpha-MSH) in the central nervous system and pituitary of the elasmobranch fish Scyliorhinus canicula was determined by the indirect immunofluorescence and the peroxidase-antiperoxidase methods using a highly specific antiserum.
(13) The receptor-rich postsynaptic membrane of the elasmobranch electric organ was fixed by quick-freezing and then viewed by freeze-fracture, deep-etching and rotary-replication.
(14) Stomachs of adult teleosts and elasmobranchs reacted to an anti-embryonic chicken pepsinogen antiserum (anti-ECPg) as well as to an anti-adult chicken pepsinogen antiserum (anti-ACPg).
(15) The effects of starvation (up to 150 days) on the concentrations of blood metabolites were studied in a teleost (bass) and an elasmobranch (dogfish).
(16) The distribution of immunoreactive neuropeptides was investigated in the retina of three species of skates (Raja clavata, R. radiata, R. oscellata), elasmobranch fish often used in electrophysiological work on the retina.
(17) Compound field potentials were recorded with up to 18 microelectrodes in comb, brush, or spear arrays on and in the optic tectum and with suction electrodes from the distal stump of the cut optic nerve and from the optic nerve head in the opened eye in elasmobranchs and teleosts.
(18) Immunoreactive hypocalcin was demonstrated in the plasma of a teleost (flounder), but not of an elasmobranch (dogfish).
(19) The role of a renin-angiotensin-like system (RAS) in the regulation of blood pressure and drinking has been investigated in the elasmobranch, Scyliorhinus canicula.
(20) The occurrence of NaCl and fluid secretion in glomerular proximal tubules of teleosts, elasmobranchs, and reptiles and in mammalian renal tissue cultures suggests that the genetic potential for NaCl secretion is present in every vertebrate kidney.
Selachian
Definition:
(n.) One of the Selachii. See Illustration in Appendix.
Example Sentences:
(1) In cuttlefish, as in selachians and mammals, spermiogenesis is characterized by the double nuclear protein transition histones----intermediate protein (protein T)----protamine (protein Sp).
(2) The purine nucleotides were determined in the whole blood of 9 fresh water teleosts and 2 marine selachians.
(3) The low levels obtained in all parameters analyzed in the selachian were remarkable.
(4) In gastric glands, triangular or oval immunopositive cells never in contact with each other were detected; their numeric ratio seems to be rather constant even if their numeric frequency and distribution vary according to the histomorphological aspect of selachian gastric glands.
(5) The author presents in this paper some data of the sexuality of Selachian Fishes chiefly first size of sexual maturity and sexual dimorphism (size, morphology, ethology and others).
(6) The author comments general data about the relationships, between size versus body-weight or the weight of other organs (liver, gonads, nidamental glands...), and on the condition in the Selachian fishes mainly in the species of Tunisian coasts.
(7) Whole blood purine nucleotides were determined in 19 species of selachians and 27 species of marine teleosts.
(8) These results indicate that the complexity level of this Selachian cerebellum is not far from cerebella of some primitive mammals.
(9) In order to clarify morphology and function(s) of the terminal nerve, gross examinations of the nerve were carried out in 9 species of selachians.
(10) From some data about species from Tunisian coasts the author proposes method for study and evolution of fecundity of oviparous and viviparous Selachians Fishes.
(11) The author presents general data about the reproductive cycle of Selachian Fishes, chiefly based on species of Tunisian coasts.
(12) Studies with restriction enzymes (RE) have just been started in selachians, employing ALU I and HIND III in Scyliorhinus stellaris.
(13) Selachians, Amphibians, and Snakes are hypermetropic and move the lens forward to accommodate for near.
(14) A comparison of the data with those previously obtained in different species of elasmobranchs and batoids indicate the existence of a common and consistent pattern of organization of the primary visual system in all selachians.
