Bioenergetics of free-ranging juvenile scalloped hammerhead sharks (Sphyrna lewini) in Kāne’ohe Bay, Ō’ahu, HI
Metabolic and activity rates determined from free-ranging juvenile scalloped hammerhead shark pups (Sphyrna lewini) in Kāne’ohe Bay, Ō’ahu, HI, were used to develop a simplified energy budget for this population. Five shark pups were tracked using a specially designed acoustic tail beat transmitter. Previous laboratory experiments determined that tail beat frequency (TBF) and water temperature ...
متن کاملTracking the fin trade: genetic stock identification in western Atlantic scalloped hammerhead sharks Sphyrna lewini
Location or stock-specific landing data are necessary to improve management of shark stocks, especially those imperiled by overexploitation as a result of the international shark fin trade. In the current absence of catch monitoring directly at extraction sites, genetic stock identification of fins collected from major market supply chain endpoints offers an overlooked but potentially useful ap...
متن کاملDiet and trophic level of scalloped hammerhead shark (Sphyrna lewini) from the Gulf of California and Gulf of Tehuantepec, Mexico
We examined the diet and trophic level of Sphyrna lewini in the Gulf of California (GC) during 2001 and in the Gulf of Tehuantepec (GT) during 2005 using data from stomach content and stable isotope analysis of δ15N and δ13C. S. lewini diet was represented by pelagic and benthic prey species where the most important in weight was Scomber japonicus (27.70±4.54%) in GC, while in GT it was Auxis s...

متن کاملDurophagy in sharks: feeding mechanics of the hammerhead Sphyrna tiburo.
This study investigates the motor pattern and head movements during feeding of a durophagus shark, the bonnethead Sphyrna tiburo, using electromyography and simultaneous high-speed video. Sphyrna tiburo feeds almost exclusively on hard-shelled crabs, with shrimp and fish taken occasionally. It captures crabs by ram feeding, then processes or reduces the prey by crushing it between molariform te...
