Terrestrial animals that hunt underwater animals are no longer a strange thing, but if aquatic animals hunt terrestrial species it is indeed a rare occurrence and not all creatures are able to that ability.
These are very special fish thanks to their special abilities and tactics that can catch terrestrial animals. Their goal is to fly creatures above the water or animals that travel close to the water.
10. European catfish
European catfish in the river Tarn in Albi, France has evolved to be able to catch pigeons on the river bank. Researchers aren't sure why this catfish can do this because there's no case that European catfish can do that.
Another hypothesis is that the fish has eaten all its prey and lack of food, forcing them to feed in the external environment. But that is not enough to convince why a catfish has an average size of 1-1.5 meters to hunt pigeons.
Many people believe that catfishes are too big to swim through the water along the river bank, while smaller catfish do not have enough energy to catch the pigeons. After plunging into the water and catching the prey, European catfish often sink them into the water to eat meat. According to the researchers, this fish has a successful hunting rate of up to 28%.
At first glance it may be difficult for catfish to hunt on the water but note that lions also have a successful hunting rate of 18% even when hunting in the herd and hunting terrestrial animals. So this is a record for a fish.

9. Fish carrying basket (Archer fish)
True to its name, fish archers are a type of fish with a talent for "good marksmanship". It often hunted animals that landed on branches hanging above the water. It seems that this is a safe place for many small insects but it turns out this is also extremely dangerous place if they unfortunately caught sight of archer fish.
Instead of jumping and jumping on the water. This fish will shoot a strong jet of water from the mouth towards the prey.
Water rays with strong shooting force when sprayed out of this fish's mouth will make prey quickly fall into the water and bait them.
8. Killer whales
The killer whale is a fairly large predatory fish, but much smaller than a typical whale. They have black upper body and white abdomen. Their common prey includes seals, seabirds, octopus, turtles, sharks and even whales.
Although living in the sea, killer whales are not necessarily fish. They are mammals of the dolphin family. Even so, this species' special hunting habits deserve to appear on the list. Killer whales often dive into the air to grab birds flying near the water or terrestrial animals wandering along the coast.
7. Silver arowana
This is a predatory fish found mainly in South American waters. It has the ability to jump out of the water to catch birds, insects and snakes from branches sticking out of the water.
Their common prey is spiders, beetles, small and solid birds. Their actions were so fast that the prey almost slipped into its mouth before realizing what had just happened. Silver arowanas are up to 1 meter long and can jump up to 2 meters from the water.
In South America, they are also called monkeys because they jump high out of the water. They seem to prefer to hunt terrestrial species rather than underwater fish. Silver arowanas are so accustomed to hunting on the water that when they are raised in tanks, they often develop drooping eyes, that is, one or both of their eyes collapse and cannot look up anymore due to the habit. Look up and look up .. This is because their owners often let food sink to the bottom of the lake and the prey swim below the silver arowana.

6. Tiger sharks
Tiger sharks in the Gulf of Mexico seem to be able to grasp the journey of migrating birds from far away so they often wait for the opportunity, when birds are tired of losing their way to the water to rest. rest. This is also a good time for tiger sharks to attack and turn these birds into meals.
Marcus Drymon, a researcher from the Dauphin Island Laboratory had the opportunity to catch some tiger sharks off the Alabama coast when they vomited fur. Then, Drymon conducted gastric surgery by 50 other tiger sharks. Unexpectedly, he discovered the body of the mines, feathers and legs of species like falcons, woodpeckers and starlings.
5. Fresh fish (catfish)
The fish have evolved by leaving the water surface to hunt on land. Although their food is mostly underwater, this fish also likes to eat beetles on the water. However, to catch them, the fish have to dive to the surface to hunt.
When they find their prey, they often stick up and use strong jaw muscles to catch the bugs before pulling them down into the water. Thanks to evolution, this fish has a fairly solid spine system, which makes it easy to drink its body when hunting.
The fish with this special name has a habit of moving on the water, especially walking on the mud by gliding through it.
They adapt very well to terrestrial habitats through their ability to breathe by gills and through the skin, mouth and throat. In particular its front fins can function as legs. Their favorite prey is insects, worms and other small mudskippers.
Some species even go far from the water, although most still need a wet environment and swamp. The mudskipper even mate and mark the territory even on the water.
3. African tiger fish
Unlike silver arowana, which often focus on hunting insects and birds climbing on branches near the water, African tiger fish only focuses on hunting terns flying above the water.
It could do this thanks to its elongated body, which could be up to 1 meter long and sharp teeth with fangs. Interestingly, this is the only freshwater fish capable of hunting in this way.
For each bird, African tiger fish have different hunting methods. Its most common tactic is to hit the bird from the surface of the water before jumping up and grabbing the prey. Another way is to hide under the water and jump out of the water to catch the prey as it flies by.
2. American snakehead fish
Snakehead fish also have the ability to hunt on land. They originated in Asia but now become a mysterious invasive species on American rivers. The reason is that this fish is legally imported from Asia to the United States for food and livestock. So many people suspect that someone may have dropped them into the river. And since then, this fish has been blooming and gradually appeared in many rivers in the United States.
In the Potomac River alone, there were more than 21 thousand snakehead fish. These fish often leave the water surface to hunt on land. In Australia, this fish has been found to hunt birds, rodents and even snakes. When hunting, fish often wriggle through the mud to search for prey. They often swallow their prey immediately after catching it.
1. Dot salmon
Salmon is a freshwater fish with a colorful body and dark spots around the body. It is known for its ability to jump high into the air and often fight very aggressively when caught.
The menu of this species is diverse, from insects to small fishes and even small terrestrial mammals. In a 2013 study, scientists found that in a belly salmon, there were 20 mice in the abdomen. Accordingly, the researchers found that the fish eats both hamsters and other small mammals around where they live.
Scientists are not sure how to hunt the fish but they think they catch prey when they are wandering near the river. For example, the shrews have a habit of wandering along the river to feed.
