If people hadn’t taken pictures of jumping out of the water to eat fish, many people would not believe that a fish swimming in the water can drag a bird flying in the sky into the water to swallow it. After all, this is too unreasonable. , It is too like a movie plot, and when it does happen, people will naturally turn their eyes on the jaw-dropping fish.
Shēn is also called giant trevally. In fact, from the word “giant”, people can vaguely perceive that they can catch and eat birds. Body type related.
Indeed, as a large pelagic fish, the trevally is large and swims fast, and is known as the "beast" in the water.
According to records, the largest known trevally has a body length of 1.7 meters, a weight of 80 kg, and a maximum speed of more than 60 kilometers per hour.
Even if you don’t look at "the most", the average length of an adult trevally is 1 meter and a weight of 30 kg. This fish is very adaptable and can be found in various marine environments such as estuaries, shoals, bays or lagoons. Can find them, no matter where they are, the trevally is also the top predator dominating a party.
What kind of animal eats, you have to find the answer in their stomach.
So far, humans have found undigested fish, crustaceans, , cephalopod, mollusks in the stomach of rare trevally, and even found small turtles, little dolphin , Blacktip reef sharks, of course, including the remains of seabirds mentioned at the beginning of the article.
Let me talk about the common foraging mode of rare trevally.
Since the trevally is in the ocean, it is daily life to prey on aquatic creatures, but we must pay attention to skills in our daily life. Adult rare trevally are "lone travelers", and schools of fish will only gather together during the breeding season.Therefore, hunting prey on their own is a means of making a living that every individual needs to master. Faced with smaller prey, rare trevally prey without pressure. They rely on their big eyes and mouth to eat whatever they want.
And if the trevally targets larger animals, then their predation will be more cautious. For example, in the face of blacktip reef sharks, trevally will use head strikes. Attack in order to stun the opponent.
In addition, rare trevally will also use other animals very well. For example, they will swim with monk seals that prey on them, and then either sit and enjoy the benefits directly or grab food from the seals.
Let's look at the advanced predation techniques of rare trevally.
For fish, catching birds is certainly not an easy task. Even rare trevally can only be done occasionally. The rare trevally catching birds that most people say nowadays actually only happened on the coast of the Seychelles in the Indian Ocean. The rare trevally habitats in the Pacific and Atlantic have not been found so far. So before we start to talk about the rare trevally catching birds, we must be clear that this is not common, and in order for the rare trevally to catch a bird, it must meet the two prerequisites of the bird flying low enough and the fish jumping high enough.
Closer to home, before the rare trevally catches the birds, it is bound to go through a period of "tracking", they will follow the flocks of tern or other seabirds, and lock the target at the stage of learning to fly Young birds, once these young birds get too close to the surface of the water, the rare trevally has an opportunity to swim faster and jump out of the water in a timely manner, catching the bird in mid-air in a blink of an eye.
can complete the action of "jumping" because the muscular strength of the trevally is very strong, and the speed of the trevally is increased to about 60 kilometers per hour through the swing of the body, and it reaches a height of 1.8 meters to 2 meters when jumping.
In fact, the rare trevally once made humans timid, but in general, it will not actively attack humans. However, according to records, there was a fisherman in Hawaii who used to fish with a spear.Three ribs were broken by the trevally.
In addition, fishing enthusiasts who are keen to catch rare trevally must not only prepare the fishing line and rod to be torn off by the hooked trevally, but also use special nets and fishing lines. Therefore, It is conceivable that the trevally is powerful and capable.
When it comes to this, some people may ask, since someone specializes in fishing rare trevally, can they eat the fish caught?
The answer may be disappointing. It is said that the rare trevally not only tastes bad, but may also cause ciguatera toxin poisoning. You must know that this toxin is dozens of times stronger than tetrodotoxin . No one should want to try it. As for the fish that are caught, most of them will be put back into the water, so in the face of the rare trevally, the angler just wants to enjoy the fun of competing with the beasts in the water.
