Which is the Fastest Fish in the World?
Do you know which is the fastest fish in the world? This incredible swimmer reaches speeds of 110 km/h and uses a giant fin to hunt. Let’s discover the secrets of the ocean's ultimate speed champion.
The ocean's home to some pretty incredible animals. Some of them, like the whale shark, are the size of a school bus, those massive, gentle giants, while others, like that teeny paedocypris fish are tinier than the tip of your finger. While some are built for speed and power, do you know which fish holds the title of 'fastest in the ocean'? Well, in this article, we'll take a closer look at the ocean's quickest swimmers and figure out which one is the real speed champion.
Which is the Fastest Fish in the World?
The Sailfish is commonly regarded as the fastest fish in the ocean. These torpedo-shaped predators can reach a speed of up to 110 km/h (68 mph). You'll usually find them cruising the warm waters of the Atlantic and Indo-Pacific Oceans.
Their status as top predators helps keep the smaller sea creatures in check. Sailfish mainly stick to a diet of little fishy friends like sardines and anchovies, as well as squid and octopus.
They hunt by corralling schools of fish together with that impressive sail on their back and then strike with a swift jab from that pointed bill of theirs. There are actually just two main types: the Atlantic Sailfish and the Indo-Pacific Sailfish.
They can even change colour when they're excited or on the hunt, which makes them one of the most beautiful and smartest athletes in the sea.
Did You Know?
- The Sailfish is officially clocked at speeds that would get it a speeding ticket on most highways.
- They usually keep their large sail folded down to swim faster, but they raise it suddenly to scare or confuse their prey.
- A baby Sailfish is tiny, but it can grow up to 4 or 5 feet long in just its first year of life!
- While they love the surface, they can dive deep into the ocean to find food, demonstrating great strength and endurance.
