Answer 4

World Almanac For Kids
Fastest Animal peregrine falcon, a bird (100-200 miles per hour)
Fastest Marine Animal blue whale (30 miles per hour)
Fastest Land Animal cheetah (70 miles per hour)
Fastest Fish sailfish (68 miles per hour)
Fastest Bird peregrine falcon (100Ð200 miles per hour)
Fastest Insect dragonfly (36 miles per hour)

Elasmo-research.org
Killer Whale (Orcinus orca) 34.5 mph

The flying fish can surpass this when gliding. When leaping these other fish can surpass this speed. Here they are in order of slowest to fastest: the mahi mahi, bonito, albacore, blue-fin tuna, yellowfin tuna, wahoo, marlin, swordfish and sailfish at 68 mph.

This is something you have to be careful with. You run into the same problem when trying to figure out the fastest bird. Is the speed they are clocked at when flying or diving? The same goes with marine animals, is the speed they are clocked when they are swimming or leaping or gliding?

When trying to find the fastest bird you will be told that it is either the Peregrine Falcon or the Spine-tailed swift. This is because one can fly faster and the other can dive faster. Usually you'll be told it's the Peregrine Falcon because it can dive extremely fast. But the Spine-tailed swift can fly the fastest.

Answer 5

Bluefin tuna, Thunnus thynnus, are among the largest and fastest marine fish. An adult may weigh 1,500 pounds and swim up to 55 miles per hour.

Answer 6

Blue Whale, largest whale, and the largest living creature on Earth. Blue whales are found in all oceans of the world. Most populations migrate extensively, traveling from the Tropics or near Tropics in winter to the edges of the pack ice in the northern and southern hemispheres in summer. Blue whales produce loud, low-frequency moans that travel over thousands of kilometers underwater. It is likely that they communicate by means of these moans, enabling the members of a group to remain in contact across a vast expanse of ocean.

Answer 7

Another problem with quantifying the speed of a marine animal, is whether you are measuring the speed it can maintain over long distance (cruising speed), speed in fast sprints or leaps out of the water (sprinting speed, or escape speed), or the acceleration speed of an attack from ambush - possibly only sustained over a meter or less in distance.

Although some types of critters, like moray eels or mantis shrimp cannot swim fast at cruising speed, they can be blindingly fast at acceleration to attack. In fish, a snake-like or eel-like body form (known as anguilliform) is ideally suited for acceleration at the expense of cruising speed. The entire body acts to push the body forward.

Squid using jet propulsion through their siphons are also extremely good at acceleration, even if their normal swimming speed isn't that high. Their long arms can also shoot out at blinding speeds to catch prey.

A torpedo-like body, with a narrow caudal peduncle, such as is seen in fast cruising fish like tuna, swordfish and mako sharks, as well as other critters like dolphins and extinct ichthyosaurs makes for high cruising speed, but sucks for acceleration. Once the critter is up to speed, small sculling actions of the tail can maintain the speed generated as the low drag, torpedo-like body slips easily through the water. This body form is generally known as thunniform.

It's difficult to measure exactly how fast extinct marine critters like mosasaurs and plesiosaurs could swim without knowing their exact metabolic rates, or what adaptations to reduce drag their scales may have had, but by comparing body shapes, and contrasting them with living analogs, it's possible to get an idea of how fast they may have swum.

Mosasaurs, with long, sinuous bodies were probably good at acceleration, but not so much at cruising speed. Plesiosaurs, powered by powerful flippers, would have swum very much like sea turtles. The long neck of some of the plesiosaurs, such as the elasmosaurs, would have been very swift at acceleration (but just the head and neck). Many of the ichthyosaurs had body shapes and sizes very similar to some of the fastest tuna, and marlins. Their long beaks may have acted much like the swords of swordfish and marlins to break up water turbulence and reduce drag. Thus some of the ichthyosaurs may have been almost as fast as some of the fastest fish of today. There's little evidence that they would have been faster though.
