They showed mathematically that drag on undulatory swimmers (such as dolphins) can indeed be greater than the muscle power it generates to propel itself forward, without being paradoxical. They introduced the concept of "energy cascade" to show that during steady swimming all of the generated muscle power is dissipated in the wake of the ...
This includes the sperm whale, oceanic dolphins, usually pilot and Orcas, and a few beaked whale species. The most common species to strand in the United Kingdom is the harbour porpoise ; the common dolphin ( Delphinus delphis ) is second-most common, and after that long-finned pilot whales ( Globicephala melas ).
The “super pod” of Risso’s dolphins was spotted in Carmel Bay, off central California’s coast. This species , which can grow to over 10ft long and weigh as much as half a metric tonne, is ...
The reniculate kidney is a multilobed kidney found in marine and aquatic mammals such as pinnipeds (seals, sea lions and walruses) and cetaceans (dolphins and whales) but absent in terrestrial mammals except bears. [1] Kidneys of this morphology have increased surface area for removing toxins from the body more efficiently than a non-lobed kidney.

A: What if, instead of limiting uncontrolled intersections (ones without signs or signals) to neighborhoods, we pulled out the signs and lights at intersections all over our cities? What would happen?
The dolphins' heart rates increased during ascent. The heart rates during a dive of these actively swimming dolphins were similar to heart rates of a sedentary dolphin at 2 m depth, showing that the heart rate response in diving dolphins is dominated by the diving response and not by an exercise response.
