...Yannis P. Papastamatiou; Christopher G. Lowe SUMMARY Changes in gastric pH of leopard sharks Triakis semifasciata were quantified as an indicator of feeding frequency and ration size. Continuous in situ measurements of gastric pH were made in captive adult leopard sharks using an autonomous pH...

... s –1 ) in the leopard shark Triakis semifasciata . Analysis of lateral displacement along the body indicates that the leopard shark is a subcarangiform swimmer. Longitudinal variation in red muscle strain was observed with strain amplitudes ranging from ±3.9% in the anterior,±6.6% in the mid...

... predators; thus, it is reasonable to expect that they might also be capable of such behavioral modulation. In this study, I investigated the effect of prey item size and type on prey-capture behavior in leopard sharks ( Triakis semifasciata ) that had been acclimated to feeding in the laboratory. Using high...

...N. Chin Lai; Jeffrey B. Graham; Louis Burnett ABSTRACT Changes in vascular pressures, blood respiratory properties and blood gas transport induced by swimming were investigated in the leopard shark Triakis semifasciata (Girard). In resting sharks, the mean ventral and dorsal aortic pressures...

...N. Chin Lai; Jeffrey B. Graham; William R. Lowell; Ralph Shabetai ABSTRACT Changes in pericardial pressure, pericardial fluid volume, cardiac stroke volume and heart rate induced by swimming were monitored for Triakis semifasciata (Girard). Maximum pericardial pressure (P max , 0.07±0.03kPa...
