| functional consequences of structural differences in stingray sensory systems. part i: mechanosensory lateral line canals. | short range hydrodynamic and electrosensory signals are important during final stages of prey capture in elasmobranchs (sharks, skates and rays), and may be particularly useful for dorso-ventrally flattened batoids with mouths hidden from their eyes. in stingrays, both the lateral line canal and electrosensory systems are highly modified and complex with significant differences on ventral surfaces that relate to feeding ecology. this study tests functional hypotheses based on quantified differen ... | 2009 | 19749095 |
| functional consequences of structural differences in stingray sensory systems. part ii: electrosensory system. | elasmobranch fishes (sharks, skates and rays) possess highly sensitive electrosensory systems, which enable them to detect weak electric fields such as those produced by potential prey organisms. different species have unique electrosensory pore numbers, densities and distributions. functional differences in detection capabilities resulting from these structural differences are largely unknown. stingrays and other batoid fishes have eyes positioned on the opposite side of the body from the mouth ... | 2009 | 19749096 |
| comparing deep-sea fish fauna between coral and non-coral "megahabitats" in the santa maria di leuca cold-water coral province (mediterranean sea). | two experimental longline surveys were carried out in the santa maria di leuca (sml) cold-water coral province (mediterranean sea) during may-june and september-october 2010 to investigate the effect of corals on fish assemblages. two types of "megahabitat" characterized by the virtual absence of fishing were explored. one was characterized by complex topography including mesohabitats with carbonate mounds and corals. the other type of megahabitat, although characterized by complex topographic f ... | 2012 | 23028551 |
| comparative anatomy of the extraocular muscles in four myliobatoidei rays (batoidea, myliobatiformes). | extraocular muscles are classically grouped as four rectus and two oblique muscles. however, their description and potential associations with species behavior are limited. the objective was to characterize extraocular muscles in four myliobatoidei rays from diverse habitats with divergent behaviors. heads (10 per species) of dasyatis hypostigma, gymnura altavela, mobula thurstoni and pteroplatytrygon violacea were decalcified and dissected to characterize and describe extraocular muscles. princ ... | 2016 | 26853799 |
