The Top 10 Fastest Sea Animals. Flyfish usually attain speeds up to 35 miles per hour when they leap out of the water, which is why their torpedo-shaped bodies with pectoral fins on their sides and pelvic fins, along with dorsal and anal fins far back on their body make them so fast. The bluefin tuna, which has been clocked at 43 miles per hour, is one of the only types of fish that are warm-blooded, which is one of the reasons it’s so fast.
Unfortunately, bluefin tuna are endangered due to overfishing. The black marlin is the fastest fish in the ocean; it has low, rounded dorsal fins and pectoral fins that are so rigid that they can’t be pressed against its sides to lower the amount of drift caused by drag.
What are the 10 fastest sea animals? As anyone who’s been swimming knows, it’s harder to move in water than it is in air because water is denser than air, meaning there are more molecules in a given space than there would be molecules in that space under the same pressure and you need a streamlined or torpedo-shaped body to reduce friction as you travel through saltwater.
#10 Fastest Sea Animal: Killer Whale – 32 mph
Also called the orca, this beautiful marine mammal with its sleek black and white livery has been clocked at 32 miles per hour when leaping out of the water. The killer whale’s head is wider than it is long, and it has a large mouth with pointy teeth.
It has wide paddle-shaped flippers that are large for its shorter body. In the wild, Orcas prefer colder waters just off the coast, but they also like moving into rivers to find warmer water. They’re typically found from the Arctic Ocean to the Caribbean and around the equator in both oceans.
#9 Fastest Sea Animal: Flying Fish – 35 mph
Flying fish do not actually fly. However, they do leap out of the water at a speed of about 35 miles per hour. Sometimes, the fish get so high in the air that they land on boat decks or even land on the ocean surface.
Flying fish are torpedo-shaped and have pectoral fins with large pectoral fin areas nearest to their head, which allow them to glide just above the water’s surface. They can be found in all of the oceans around the world except Antarctica. They’re particularly common in open waters during dusk and dawn when they play a role in predation for many predators including dolphins and sharks like sailfish.
#8 Fastest Sea Animal: Mako Shark – 40 mph
Mako sharks are a fast and powerful species of fish. They have been around since the time of dinosaurs, but they are currently endangered. There are two species of mako shark: the great white (which is smaller) and the shortfin mako shark.
Their favorite foods include both living and dead fish, which they hunt at speeds up to 40 miles per hour. They can swim as deep as 490 feet, at depths that range from the surface to 490 feet.
#7 Fastest Sea Animal: Bonito – 40 mph
Bonito is a small fish, who can reach speeds of 40 miles per hour. Bonito is a member of the mackerel family and has both an Atlantic and Pacific species. The Atlantic Bonito is three feet long, silver at the bottom and blue at the top with a wide, compressed body.
It’s found in the temperate and tropical seas near the coast and close to shore; oftentimes it spends time in Argentina. The Pacific Bonito is medium-sized and has stripes on their back that cover their side; they’re found from Chile north to Alaska.
#6 Fastest Sea Animal: Atlantic Bluefin Tuna – 43 mph
Growing up and all over, the bluefin tuna is an unusual fish. This species is able to breathe and survive through water more efficiently than many other fish, which allows it to swim at speeds of up to 43 miles per hour.
While they can live to be 50 years old, fishing has severely crippled the population of this fish with an endangered designation on the International Union for Conservation of Nature Red List. With their fecundity, females can produce 30 million eggs at a time which has helped slow the devastation of their population but not enough as there are still too few bluefin tuna in the sea.
#5 Fastest Sea Animal: Pilot Whale – 47 mph
The pilot whale, sometimes called the blackfish, is actually a large dolphin. In addition to its intelligence, it is also known for its speed. Social and eco-friendly, it spends time stranded but often gets caught in nets meant for other fish.
It has a dark brown, dark gray or dark black body that has a white patch right behind its dorsal fin. Its melon or bulbous head can be seen with ease due to its large size. There are two species of pilot whales – long-finned and short-finned. The long-finned pilot whales can grow to about 21 feet in length and three feet longer than females in the short-finned category.
Male short-finned pilots grow to about 24 feet in length and weigh over 3.5 tons – making their speed all the more impressive!
#4 Fastest Sea Animal: Yellowfin Tuna – 50 mph
The yellowfin tuna is warm-blooded and has the body structure to swim quickly. It’s found in warm seawater, which gives it its chocolate color. Its second dorsal and anal fins are yellow fins, which sets it apart from other species. Since it can live over 100 years, it’s a grand old fish.
Its tail is striped and many of its shades of color change with the world around it. There are darker tones on top and a lighter white belly with blue stripes marbling them together. This powerful fish is not just a fast swimmer, but also a long distance swimmer.
It forms schools with other fish as well as dolphins and porpoises when it moves across the ocean. Many people love eating its flesh because of how delicious it tastes, but commercial targeting of this guy has made him an endangered creature since 2005
#3 Fastest Sea Animal: Swordfish – 60 mph
In the animal kingdom, some of the fastest fish in the oceans are called swordfish. Simply put, it’s torpedo-shaped and has long and compressed body that allows it to swim at up to 60 miles per hour!
Its first dorsal fin is tall, curved, and the second is much smaller and near its tail. It lives near shore in open seas and can dive as deep as 198 feet. It’s found in the Atlantic from Newfoundland down to Argentina and in the Pacific from Oregon down to Chile.
#2 Fastest Sea Animal: Sailfish – 68 mph
Another billfish is the sailfish. This fish, which can reach speeds of 68 miles per hour when leaping out of the water or plunging into a school of prey, is smaller than the swordfish at around 11 feet in length and usually weighs only about 182 pounds.
Like the swordfish, it has a compressed, long, tapering body with a dark-blue top and silvery belly with golden spots on its sides. Its spectacular dorsal fin gives this fish its name, for it stretches nearly the length of the animal’s back. Not only does this fish use its long bill to slash at its prey but also folds into a groove on the back to make hunting easier!
#1 Fastest Sea Animal: Black Marlin – 82 mph
Though the sailfish is usually thought to be the fastest animal in the ocean, the black marlin may have bested it. The black marlin is a larger fish that lives in the Pacific and Indian oceans. It reaches speeds of 80 mph but only swims 22 mph on average.
It has a smaller head than the sailfish and its dorsal fin is lower and rounder. Like its name suggests, it has discolored scales with dark spots that makes it hard for prey to stay hidden from view.
