| nesippus orientalis heller, 1868 (pandaridae: siphonostomatoida): descriptions of the adult, young and immature females, a first description of the male and aspects of their functional morphology. | nesippus orientalis heller, 1868, a cosmopolitan species found in the mouth and on the gill-arches of a number of shark hosts, is distinguished from other species by the presence of dorsal plates on the fourth thoracic segment. specimens were collected from various sharks caught in the nets of the natal sharks board, off the coast of kwazulu-natal, south africa. collected specimens were preserved in 70% ethanol and studied using the wooden slide technique and scanning electron microscopy. carefu ... | 2006 | 16676230 |
| cytochrome oxidase i sequences reveal possible cryptic diversity in the cosmopolitan symbiotic copepod nesippus orientalis heller, 1868 (pandaridae: siphonostomatoida) on elasmobranch hosts from the kwazulu-natal coast of south africa. | over the past decade, numerous molecular phylogenetic studies uncovered cryptic diversity within the copepoda, yet very few investigations focused on symbiotic copepods. here we report mitochondrial dna cytochrome oxidase i diversity in the cosmopolitan elasmobranch symbiont nesippus orientalis off the kwazulu-natal coast of south africa. analysis of partial coi sequences of copepods sampled from a diversity of shark hosts, revealed the presence of two divergent clades. diversity within the clad ... | 2010 | 19723521 |
