| the role of pelagic swarm fish (myctophidae: teleostei) in the oceanic life cycle of anisakis sibling species at the mid-atlantic ridge, central atlantic. | first information is provided on the parasitation and feeding ecology of the myctophid fish species myctophum punctatum and notoscopelus kroyeri from the mid-atlantic ridge (mar), central atlantic. four different parasite species were found in both fish with a similar high prevalence and intensity of infestation. the digeneans gonocerca phycidis and lethadena sp. were isolated as adults from the stomach, larval tetraphyllidean cestodes (scolex pleuronectis) from the intestine, and genetically id ... | 2008 | 18758825 |
| early development of eye and retina in lanternfish larvae. | the morphological characteristics of the eyes and the retinae of lanternfish larvae of lampanyctus crocodilus, benthosema glaciale, and myctophum punctatum were analyzed in pre-flexion, flexion, and post-flexion stages. pre-flexion larvae of l. crocodilus, the species with the shallowest depth distribution, had spherical eyes located antero-laterally on a strongly laterally-compressed head, suggesting a forward binocular visual field. b. glaciale and m. punctatum larvae live deeper in the water ... | 2007 | 17822580 |
| two microsporidian parasites found in marine fishes in the atlantic ocean. | two new species of microsporidia are reported from the atlantic marine fishes: pleistophora duodecimae sp. n. from skeletal musculature of the rat-tail, coryphaenoides nasutus günther and glugea capverdensis sp. n. from the intestine, mesentery and ovary of the lantern fish, myctophum punctatum rafinesque. formation of secondary xenomas was observed in the latter species. both species may inflict serious damage upon their hosts. | 1980 | 6774932 |
