... electrocardiogram (ECG) in the beluga whale, bottlenose dolphin, false killer whale, killer whale ( Orcinus orca ) and pilot whale ( Globicephala macrorhynchus ) to evaluate cardiorespiratory coupling while breathing spontaneously under voluntary control. The results show that cetaceans have a strong respiratory...

... with a significant difference between low fat (13.9±4.8 days) and high fat diets (22.0±0.5 days). Overall, our results indicate that while assuming a Δ 13 C value of 1‰ may be appropriate for cetaceans, Δ 15 N values may be closer to 1.5‰ rather than the commonly assumed 3‰. Our data also suggest that understanding...

...John Davenport; Liz Cotter; Emer Rogan; Denis Kelliher; Colm Murphy SUMMARY Cetaceans are neckless, so the trachea is very short. The upper respiratory tract is separate from the mouth and pharynx, and the dorsal blowhole connects, via the vestibular and nasopalatine cavities, directly...

...Joseph L. Kirschvink; Andrew E. Dizon; James A. Westphal ABSTRACT We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smithsonian compilation which...
