When it comes to the fastest marine animals, many think of sharks or dolphins, but the true record holder is the sailfish (Istiophorus), capable of reaching speeds of up to 110 km/h underwater.
This impressive fish not only stands out for its speed but also for its agility and dexterity, making it one of the great predators of the ocean.
## The characteristics that make it so fast
The sailfish has a perfectly hydrodynamic anatomy designed to move with maximum efficiency in the water:
– Long and muscular body, which reduces resistance.
– Pointed jaw, similar to a spear, ideal for attacking its prey.
– Dorsal fin shaped like a sail, which can be folded when accelerating.
Thanks to these qualities, the sailfish is able to propel itself with great power, minimizing friction and performing surprising maneuvers.
## How was it proven to be the fastest fish?
Speed measurements have been carried out in natural environments and controlled aquariums, where scientists have observed that these fish can reach bursts of 110 km/h at key moments, such as:
– Hunting for schools of fish, where it displays its maximum speed.
– Escaping predators, allowing it to survive in a competitive environment.
## A formidable predator of the ocean
The sailfish not only relies on its speed but also employs advanced hunting strategies, using its:
– Sharp beak, similar to that of a swordfish, with which it stuns and devours fish.
– Ability to change color, showing bright stripes that help it communicate with other sailfish or camouflage itself.
## The sailfish and sport fishing
Due to its size, strength, and spectacular nature, the sailfish is the target of sport fishing, leading various organizations to promote its conservation through catch and release practices.
While not endangered, its protection is key to maintaining ecological balance in the oceans.
