There are more problems with speed in the water, as it offers more resistance to the air. In fact, water has a density approximately 800 times that of air and its viscosity is approximately fifty times that of air. Still, many marine animals swim fast due to their design.
The streamlined shape and soft skin of the dolphin minimize friction in the water. These small whale-like mammals are fast and graceful swimmers and can make sharp turns and sudden stops. They swim by moving their tail and back up and down and moving large amounts of water. You are obviously running in the water at around 40 km / h, but a dolphin was zigzagging through a boat moving at 60 km / h.
Sharks can seem like slow creatures, like when they search for something to eat. However, if necessary, they accelerate sharply, and the mako shark reaches a top speed of around 35 mph. Experiments with a blue shark showed that it could reach 69 kilometers per hour in a small burst of speed.
"One of the accompaniments with the most perfect forms that are known", this is how tuna is described. The slim body of the tuna is designed to travel fast and glide through the water with minimal effort. Obviously, tuna can travel at speeds of around 40 miles per hour. And how they love to travel! A bluefin tuna was tagged by scientists on Cat Cay, Bahamas. It was captured off the coast of Bergen, Norway, 122 days later, approximately 5,300 miles!
The squid that crawls across the seafloor with its tentacles is generally not considered a sprinter. But when the squid sees the danger, it provokes a reaction to escape. This live stream fills their thick, muscular fur with water and expels it through a movable funnel that can be turned in any direction. Go far! A giant underwater octopus in the South Pacific said: "With great effort, it can shoot 15 to 30 meters back like a rocket, almost faster than the eye can track. It is a tiger spring, the fastest movement. I saw it in the world of water "".
Like squid, squid is an incredible runabout. When squid are in a hurry, they just serve so many people - they take a plane. In fact, speed is the specialty of these ten-armed creatures, which can reach 18 meters in length. Despite all its arms, squid have a slender shape. The epitome of a rocket, an octopus can instantly change direction and jump up and down, back and forth, the latter being its usual way of traveling.
When an octopus is attacked by a dolphin, it releases an octopus-like drop of ink to fool the enemy. Then Mr. Lula takes a neutral color and is pulled. How fast can an octopus do that? Dr. Gilbert L. Voss, an authority on octopuses, says: "Nobody really knows how fast octopuses can swim because their movements are so erratic. They are certainly among the fastest animals in the oceans. Some can even get out from the ocean. Water ten to forty feet and gliding over thirty feet in the waves. It's not uncommon for them to land on the deck of ships. "No power crisis for Jet Squid!
Many other marine animals are also spectacular sprinters. For example, the barracuda is said to travel at 30 miles per hour; Blue marlin can go up to 50 miles per hour. But perhaps the fastest fish is the sailboat, a great variety of swordfish. According to C. W. Coates and J. W. Atz, curator and assistant curator of the Aquarium of the Zoological Society of New York, “the Atlantic Sailfish. . . it looks like nothing more than a torpedo when it crosses the water with all its fins firmly attached to the body. . . . The fish seems to be the tip of the streamlined shape. . . . They are said to reach a phenomenal speed of sixty miles per hour underwater. According to the Guinness Book of Records, a sailboat off Florida would have traveled 68 miles per hour. The fastest fish of all!
Very good one...
