An elder who has worked on fishing boats for 30 years told me that 90% of people do not know that there is a fish called a "live torpedo" that all fishermen dare not provoke.
Because this fish is capable of not only assassinating sharks, but also penetrating the shell of submarines, all because the mouth of this fish is like a sharp saber.
First, speed: beyond the speed of the train
Swordfish is known worldwide for its extremely fast swimming ability. They have excellent muscle structure and streamlined bodies, allowing them to swim quickly in the water.
According to research, the Swordfish can reach a top speed of 109 kilometers per hour, which is faster than most ground vehicles and even faster than trains can run.
The swordfish's body design makes it virtually drag-free in the water, further boosting their swimming speed, making them one of the fastest creatures in the ocean.
Second, a sharp upper jaw and a dagger-like tip
The Swordfish was able to penetrate the submarine's titanium shell and assassinate sharks in part because of its sharp upper jaw and tip at the front of its body.
The upper jaw of the swordfish is long and prominent, forming a shape similar to a sword, hence the name swordfish.
This special mouth structure gives it extremely high penetration and piercing ability. The maxilla of the swordfish has a hard structure and contains a lot of tough muscle tissue, which can produce a strong impact force.
Moreover, their upper jaws are also covered with hard scales, further increasing their piercing power.
In addition to the upper jaw, the front of the swordfish also has a dagger-like tip. This tip, often referred to as the "sword," is one of the most distinctive features of the swordfish.
The Swordfish uses this tip as a weapon to impact the target at high speed, piercing it.
The swords of the Swordfish are very hard and sharp, sometimes even able to penetrate the hull or the solid shell of the submarine. This attack makes the swordfish one of the most lethal predators in the ocean.
Third, physiological adaptation: adapt to high-speed impact and long-term swimming
The reason why swordfish are able to hit targets at high speeds and maintain long-lasting swimming ability is because of a series of physiological adaptations in their bodies.
First of all, the musculature of swordfish is very developed, especially the pectoral and tail muscles.
These muscles provide powerful propulsion, allowing the swordfish to accelerate quickly and swim at high speeds. In addition, the heart and respiratory system of the swordfish have also undergone special adaptations to adapt to high-intensity exercise.
The swordfish's heart is powerful and efficient, able to quickly transport oxygen-enriched blood to muscle tissue, providing sustained energy for high-speed impacts.
In addition, swordfish also have special thermoregulatory abilities.
Swordfish have a higher body temperature than other fish, usually about 10 to 15 degrees Celsius warmer than the surrounding water.
This thermoregulation makes the swordfish's muscle activity more efficient, speeds up metabolic processes, and further increases its explosiveness and staying power.
4. Unique hunting skills: use speed and attack power
Swordfish do not rely solely on speed and attack power to hunt their prey, they also use unique hunting techniques. Swordfish often use their excellent eyesight and keen perception to detect prey from a long distance.
Once a target is found, the swordfish swim towards its prey at breakneck speed and launch a swift attack when approaching the target.
The swordfish's attack speed is as fast as lightning, and there is almost no hesitation, giving the prey very little chance to escape.
In addition, the swordfish is also adept at inflicting damage with its sharp upper jaw and sword-shaped tip.
Swordfish attacks are usually targeted, and they attack the vulnerable parts or torso of their prey to quickly defeat it.
The swordfish's attack power and penetration make it a top predator, capable of attacking prey larger than its own size.
All in all, the Swordfish, with its amazing speed and sharp upper jaw, became a "living torpedo" in the ocean. They gallop through the water faster than a train, using their powerful muscles and streamlined body to swim at high speeds.
Therefore, the name "live torpedo" of swordfish is well deserved, showing the wonder of biodiversity and adaptation in nature.
