Sailfish- The Fastest Fish In The Ocean

The Sailfish is capable of reaching speeds of up to 68 miles per hour (110 kp/h); however, recent studies claim this is overstated and is actually closer to 35mph (56 KPH). 

What’s amazing about the sailfish is how fast and agile they are despite being as big as 10ft long and 128 lbs in weight.

Why Are Sailfish So Fast

The high-speed swimming of the sailfish can be attributed to their elongated, slender body, which is perfectly adapted to reduce drag and increase speed, and also to the large sail-like dorsal fin, which can be raised and lowered to streamline their movement through the water.

Swordfish are another ocean dweller that can reach high speeds, the swordfish can swim up to 60 miles per hour (97 kilometers per hour), but once again, this might be overstated as recent research suggests 22 mph (36KPH) could be more accurate. 

The Swordfish is also known for its long bill, which it uses to stun its prey, 

and although Swordfish spend a lot of time very deep in the ocean, they can often be spotted on the surface airing their Dorsal fin.


There are several species of Marlin fish, so the speeds will vary, but on avg, the Fastest Marlin will be the Blue Marlin which is able to swim at an incredible 50 mph (80 km/h)

Opposed to what you might think, the significantly larger Blue Marlin is actually a faster swimmer than the smaller and more agile striped marlin.  

Marlin is also very good to eat, although they are not as popular of a dish in the United States.

You can find most varieties of Marlin in the Atlantic, Pacific, and Indian Oceans.

Bluefin Tuna (Atlantic)

Tuna fish in general are known for their endurance as well as their speed, but the Atlantic Bluefin Tuna can swim at a steady rate of up to 44 miles per hour (70 kilometers per hour).

The name of the Atlantic Bluefin Tuna is a huge tell as to which ocean you can find them in, but they are also found swimming through the waters of the Mediterranean Sea.  

Much like the Black Marlin, The Bluefin Tuna is as big as it is fast, often growing as long as 12ft and weighing up to 1,500 pounds.


Wahoo, also known as “Ono,” are incredibly fast fish that can reach speeds of up to 60 miles per hour (96 km/h).

They are able to swim at these high speeds due to their streamlined bodies and powerful tails.  They are also able to make sudden turns and sudden stops, which makes them difficult to catch for anglers.

Their speed, agility, and great taste make them a popular target for sport fishermen, who typically use high-speed trolling methods to try and catch them.

You can find Wahoo in Subtropical and Tropical waters around the world but they are known to migrate to more moderate waters in the summer.
