Angiotensin II is a potent vaso-active peptide that causes blood vessels to constrict, resulting in increased blood pressure. Angiotensin II also stimulates the secretion of the hormone aldosterone from the adrenal cortex. Aldosterone causes the tubules of the kidneys to increase the reabsorption of sodium and water into the blood.
The most reliable record of a Blue Shark at speed is 24.5 miles (39.4 kilometres) per hour for a 6.5-foot- (2-metre-) long individual. The Shortfin Mako (Isurus oxyrinchus) is probably the champion speedster among sharks.
The body is kept in an upright position because of these fins. They also possess the ability to raise their body temperature while swimming. How Fast can Sharks Swim? Whale sharks are slow swimmers and their top speed is no more than 5 miles (8 kilometers per hour) probably due to the fact that whale shark is the biggest fish in the world. It reaches a length of 40 ft (12 m) and weighs up to 13 tons (12 metric tons). Great white sharks are one of the fast movers in water. They are able to reach speeds of 25 miles per hour (40 km/h). They swim just below the waterâs surface.
