| ontogenetic changes in fibrous connective tissue organization in the oval squid, sepioteuthis lessoniana lesson, 1830. | ontogenetic changes in the organization and volume fraction of collagenous connective tissues were examined in the mantle of sepioteuthis lessoniana, the oval squid. outer tunic fiber angle (the angle of a tunic collagen fiber relative to the long axis of the squid) decreased from 33.5 degrees in newly hatched animals to 17.7 degrees in the largest animals studied. the arrangement of intramuscular collagen fiber systems 1 (im-1) and 2 (im-2) also changed significantly during ontogeny. because of ... | 2001 | 11687386 |
| ontogenetic changes in mantle kinematics during escape-jet locomotion in the oval squid, sepioteuthis lessoniana lesson, 1830. | we investigated the kinematics of mantle movement during escape jet behavior in an ontogenetic series of sepioteuthis lessoniana, the oval squid. changes in mantle diameter during the jet were measured from digitized s-vhs video fields of tethered animals that ranged in age from hatchlings to 9 weeks. the amplitude of both mantle contraction and mantle hyperinflation (expressed as percent change from the resting mantle diameter) during an escape jet was significantly greater in hatchlings than i ... | 2001 | 11687387 |
| renal organs of cephalopods: a habitat for dicyemids and chromidinids. | the renal organs of 32 species of cephalopods (renal appendage of all cephalopods, and renal and pancreatic appendages in decapods) were examined for parasite fauna and for histological comparison. two phylogenetically distant organisms, dicyemid mesozoans and chromidinid ciliates, were found in 20 cephalopod species. most benthic cephalopods (octopus and cuttlefish) were infected with dicyemids. two pelagic cephalopod species, sepioteuthis lessoniana and todarodes pacificus, also harbored dicye ... | 2004 | 15376274 |
| structural characterization and biomedical properties of sulfated polysaccharide from the gladius of sepioteuthis lessoniana (lesson, 1831). | sulfated polysaccharide was extracted from the internal shell (gladius) of sepioteuthis lessoniana. the sulfated polysaccharide contained 61.3% of carbohydrate, 0.8% of protein, 28.2% of ash and 1.33% of moisture respectively. the elemental composition was analyzed using chns/o analyzer. the molecular weight of sulfated polysaccharide determined through page was found to be as 66 kda. monosaccharides analysis revealed that sulfated polysaccharide was composed of rhamnose, galactose, xylose and g ... | 2016 | 26724686 |
