The great hammerhead shark is found in a variety of water depths such as shallow lagoons and coral reefs, and in deeper waters up to 984 feet. ... and a 360° view of their surroundings, making ...
A 2016 study of specimens logged with accelerometers showed that great hammerhead sharks reduce drag and lessen energy expenditure by swimming on their side in a posture termed "rolled swimming". The shark uses its very large dorsal fin to help achieve lift, a habit that had previously been noted in captive specimens, and may spend up to 90% of ...
