Respiratory disease is one of the main causes for morbidity and mortality in cetaceans, which highlights the importance of understanding normal lung function and how it may impede homeostasis, and diving capacity. In addition, the use of breathing frequency as a proxy for metabolic rate requires a better estimate of the normal range of tidal volume, respiratory flow, and breath durations. In the current study, we use data on c...

We used satellite‐linked tags to evaluate dive behavior in offshore bottlenose dolphins ( Tursiops spp.) near the island of Bermuda. The data provide evidence that bottlenose dolphins commonly perform both long (>272 s) and deep (>199 m) dives, with the deepest and longest dives being to 1,000 m and 826 s (13.8 min), respectively. The data show a relationship between dive duration and dive depth for dives longer than about 272...

High‐resolution dive depth and acceleration recordings from nearshore (Sarasota Bay, dive depth Tursiops spp.) were used to estimate the diving metabolic rate (DMR) and the locomotor metabolic rate (LMR, L O 2 /min) during three phases of diving (descent, bottom, and ascent). For shallow dives (depth ≤ 30 m), we found no differences between the two ecotypes in the LMR during diving, nor during the postdive shallow interval bet...
