Although dolphins do not have external hind limbs, some species have discrete rudimentary appendages, which may contain feet and digits. The killer whale can travel at the speed of 55.5 km/h (34.5 mph). But other dolphins can travel at 9–28 km/h. Dolphins have fused neck vertebrae, which increases the stability for dolphins to swim at high speed and decreases flexibility. But they cannot turn their heads. But river dolphins have non-fused neck vertebrae, they can turn their heads up to 90 ...
Dolphins have higher volumes of blood for their body size than do land animals, allowing for more oxygen carrying capacity during dives. Blood in the adult dolphin makes up 10-15% of its body weight, whereas in the human it makes up only 7% of the body weight. The dolphin's blood contains a higher concentration of red blood cells and hemoglobin than man's blood. Dolphins are able to store twice the oxygen in their muscles than can the human. By storing oxygen in their blood and muscles ...
There is a known evolutionary relationship between horses and dolphins, and it has been found that both dolphins and horses have an Ala → Ser alteration in their beta chain distal heme pocket of their hemoglobin which causes a lowered oxygen affinity relative to human hemoglobin. This alteration allows for oxygen to be delivered more efficiently during diving. This study also had a case where a dolphin was stranded and presented another form of hemoglobin not present in the other dolphin ...
