... of ketogenic precursors even in animals consuming a ketogenic diet. While mouse liver contained abundant βHB, as expected, we could not find evidence of βHB from any odontocete cetacean liver ( Fig. 1 B; Table S2 ). The direct comparison of livers from stranded dolphins collected in the field and mice under...

...Frank E. Fish; Paul Legac; Terrie M. Williams; Timothy Wei Attempts to measure the propulsive forces produced by swimming dolphins have been limited. Previous uses of computational hydrodynamic models and gliding experiments have provided estimates of thrust production by dolphins, but these were...

... during repetitive breath-hold diving is sufficient for asymptomatic VGE formation in odontocetes, a bottlenose dolphin ( Tursiops truncatus Montagu) was trained to perform 10–12 serial dives with 60 s surface intervals to depths of 30, 50, 70 or 100 m. The dolphin remained at the bottom depth for 90 s...

...T. Akamatsu; D. Wang; K. Wang; S. Li; S. Dong SUMMARY Dolphins and porpoises have excellent biosonar ability, which they use for navigation, ranging and foraging. However, the role of biosonar in free-ranging small cetaceans has not been fully investigated. The biosonar behaviour and body movements...
