pseudohexabothrium taeniurae n. sp. (monogenea: hexabothriidae) from the gills of taeniura lymma (dasyatididae) from the great barrier reef, australia.	pseudohexabothrium taeniurae n. sp. is proposed for a hexabothriid monogenean found on the gills of taeniura lymma (forsskål) off heron island, great barrier reef, queensland, australia. pseudohexabothrium taeniurae is distinguished from pseudohexabothrium rajae brinkmann, 1952, the type and only species of the genus, by the morphology of the sucker sclerites and eggs, and by the size of the hamuli, pharynx, and the "false" oral sucker. the generic diagnosis of pseudohexabothrium is revised. a p ...	1996	8627482
glands associated with the anterior adhesive areas of the monogeneans, entobdella sp. and entobdella australis (capsalidae) from the skin of himantura fai and taeniura lymma (dasyatididae).	using scanning and transmission electron microscopy, investigations were carried out on the anterior adhesive areas of entobdella sp. from the skin of himantura fai and entobdella australis from the skin of taeniura lymma at heron island, australia. all studies were of parasites detached from either host tissue or a substrate. both species of monogeneans have two characteristic anteroventral adhesive pads, one on either side of the head, subdivided to a "diadem". two types of gland cells are ass ...	1998	9602390
functional morphology of undulatory pectoral fin locomotion in the stingray taeniura lymma (chondrichthyes: dasyatidae)	rajiform locomotion is a unique swimming style found in the batoid fishes (skates and rays) in which thrust is generated by undulatory waves passing down the enlarged pectoral fins. we examined the kinematic patterns of fin motion and the motor patterns of pectoral fin muscles driving the locomotor system in the blue-spot stingray taeniura lymma. our goals in this study were to determine overall patterns of fin motion and motor control during undulatory locomotion, to discover how these patterns ...	1999	10574730
urea synthesis in the african lungfish protopterus dolloi--hepatic carbamoyl phosphate synthetase iii and glutamine synthetase are upregulated by 6 days of aerial exposure.	like the marine ray taeniura lymma, the african lungfish protopterus dolloi possesses carbamoyl phosphate iii (cps iii) in the liver and not carbamoyl phosphate i (cps i), as in the mouse mus musculus or as in other african lungfish reported elsewhere. however, similar to other african lungfish and tetrapods, hepatic arginase of p. dolloi is present mainly in the cytosol. glutamine synthetase activity is present in both the mitochondrial and cytosolic fractions of the liver of p. dolloi. therefo ...	2003	12966053
ornithine-urea cycle and urea synthesis in african lungfishes, protopterus aethiopicus and protopterus annectens, exposed to terrestrial conditions for six days.	the objectives of this study were (1) to determine the type of carbamoyl phosphate synthetase (cps) present, and the compartmentalization of arginase, in the livers of the african lungfishes, protopterus aethiopicus and protopterus annectens, and (2) to elucidate if these two lungfishes were capable of increasing the rates of urea synthesis and capacities of the ornithine-urea cycle (ouc) during 6 days of aerial exposure without undergoing aestivation. like another african lungfish, protopterus ...	2005	15828011
a new species of aberrapex jensen, 2001 (cestoda: lecanicephalidea) from taeniura lymma (forsskål) (myliobatiformes: dasyatidae) from off sabah, malaysia.	a new lecanicephalidean species of aberrapex jensen, 2001 is described from the blue-spotted fantail ray taeniura lymma (forsskål) collected off the eastern coast of sabah in malaysian borneo. this is the first record of a lecanicephalidean tapeworm from the island of borneo and the first record of aberrapex from this host species. a. manjajiae n. sp. is easily distinguished from its two congeners, a. senticosus jensen, 2001 and a. arrhynchum (brooks, mayes & thorson, 1981) jensen, 2001, based o ...	2006	16612652
metabolic organization of freshwater, euryhaline, and marine elasmobranchs: implications for the evolution of energy metabolism in sharks and rays.	to test the hypothesis that the preference for ketone bodies rather than lipids as oxidative fuel in elasmobranchs evolved in response to the appearance of urea-based osmoregulation, we measured total non-esterified fatty acids (nefa) in plasma as well as maximal activities of enzymes of intermediary metabolism in tissues from marine and freshwater elasmobranchs, including: the river stingray potamotrygon motoro (<1 mmol l(-1) plasma urea); the marine stingray taeniura lymma, and the marine shar ...	2006	16788033
retinal ganglion cell distribution and spatial resolving power in elasmobranchs.	the total number, distribution and peak density of presumed retinal ganglion cells was assessed in 10 species of elasmobranch (nine species of shark and one species of batoid) using counts of nissl-stained cells in retinal wholemounts. the species sampled include a number of active, predatory benthopelagic and pelagic sharks that are found in a variety of coastal and oceanic habitats and represent elasmobranch groups for which information of this nature is currently lacking. the topographic dist ...	2008	18679025
dollfusiella campbell & beveridge, 1994 (trypanorhyncha: eutetrarhynchidae) from elasmobranchs off borneo, including descriptions of five new species.	sampling of a large number of elasmobranchs from coastal waters off borneo revealed the presence of five new species of dollfusiella campbell & beveridge, 1994 (trypanorhyncha: eutetrarhynchidae), namely d. angustiformis n. sp., d. hemispinosa n. sp., d. spinosa n. sp., d. imparispinis n. sp. and d. parva n. sp. dollfusiella angustiformis n. sp. is described from the spiral intestines of four species of the dasyatid stingray genus himantura müller & henle from both the indonesian and malaysian p ...	2013	23949646
isolation of a novel 'atypical' brucella strain from a bluespotted ribbontail ray (taeniura lymma).	a pleomorphic gram-negative, motile coccobacillus was isolated from the gills of a wild-caught bluespotted ribbontail ray after its sudden death during quarantine. strain 141012304 was observed to grow aerobically, to be clearly positive for cytochrome oxidase, catalase, urease and was initially identified as "brucella melitensis" or "ochrobactrum anthropi" by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and vitek2-compact(®), respectively. affiliation to the genu ...	2017	27785661
