There are about a dozen of these dolphins, the longest reaching about seven meters and the short one being more than three meters.

The body size is huge.

The seven-meter-long dolphin is already relatively large in the dolphin family.

Few dolphins in the dolphin family can grow to such a size, except for the genus Killer Whale and the genus Pseudokiller Whale.

But the dolphin in front of him, with a medium-long beak and a distant forehead, is not a killer whale, but more like a short-nosed true dolphin.

On Earth, the maximum adult length of the short-nosed dolphin is about two and a half meters, and it is impossible for them to grow to such a large size.

But in this world, there are island whales that are bigger than islands, island eaters who devour islands like goldfish, and elephants who can bear a country on their backs.

Xia Qiu was not surprised to see such dolphins.

Dolphins are probably the most intelligent animals in the ocean, but there are also cephalopods such as octopuses, squids and squid.

Dolphins have a large proportion of brains, with many deep cerebral glossae and well-developed brain cells.

On top of that, they have a powerful sonar system.

They can release ultrasound waves and use echolocation to locate targets.

Moreover, dolphins have a high sensitivity to sonar, and dolphins are the mammals with the highest sensitivity of cetaceans' sonar.

They can spot a 0.2mm diameter wire and a 1mm diameter nylon rope a few meters away, can distinguish between two signals with a 200ps time, and can find schools of fish hundreds of meters away.

At the same time, their sonar also has a strong ability to distinguish between different fish, different material materials, and even the echoes of their own vocalizations can be distinguished from the echoes of human replay.

Moreover, their sonar has the ability to express emotions and can communicate with each other with a sonar system.

What Xia Qiu wanted was a sonar system.

His eyesight is far better than that of marine fish, but as his predation range increases, it is difficult to see the surrounding scene clearly in areas with relatively large water depths.

But if you have a sonar system, you can accurately capture your prey and avoid your enemies.

The higher the vibration, the clearer the perception.

Moreover, the vibration is easy to cover the impact, and the detection distance is not far.

I need a better detection system.

Whether it is the positioning ability of the sonar system, the ability to distinguish is what is needed in summer and autumn.

Catch them.

Xia Qiu came up with the idea and accelerated towards the dolphin in the distance.

This group of dolphins, who had already discovered Xia Qiu, did not take it to heart and kept a certain distance.

But when Xia Qiu rushed towards them, their speed increased suddenly, and they sensed this and accelerated their swimming.

Sou.

They are extremely fast, and their streamlined body gives them great speed.

Dolphins are very fast, reaching speeds of 30 to 40 kilometers per hour, and ordinary sharks cannot hunt them.

But summer and autumn are different.

Xia Qiu's body contains great strength, the size of its fins, and the strength of its body muscles, which far exceed those of fish of the same size.

As a result, he is extremely fast, reaching speeds of up to 45 kilometers per hour compared to the fastest great white shark among sharks.

Sou.

Xia Qiu quickly approached this group of dolphins, constantly closing the distance.

Quick, fast.

Xia Qiu approached the dolphins and soon came behind them.

Faced with Xia Qiu's pursuit, this group of dolphins suddenly scattered and swam into the distance.

Want to scatter and escape?

Xia Qiu continued to chase, but found that the dolphin did not run away, and after opening up the distance, they kept a constant distance and went hand in hand.

Do you want to attack one dolphin and let the others escape?

Xia Qiu closed the instantaneous membrane of his eyes and rushed towards a dolphin, which was rushing forward, and Xia Qiu chased with all his might.

But just when Xia Qiu chased after him, only two or three meters away, he suddenly found himself surrounded by dolphins.

The other dolphins, on their sides and behind them, wrap themselves in them.

This is?

Xia Qiu was shocked, and the next moment, these dolphins were already rushing towards him.

Want to bump into yourself?

Treat me like a shark?

Although most dolphins are smaller than sharks, they are not afraid of sharks.

In addition to killer whales, other groups of dolphins also have a strong fighting power when encountering sharks.

The speed is fast, as long as it is not a great white shark, most sharks, they can stay away from them.

Even when they encounter sharks, they rush into them in groups to drive them away.

Generally, sharks do not take the initiative to attack dolphins, the gains outweigh the losses, and occasionally attack, if they can eat one, they will be driven away.

And if it is the big brother killer whale among the dolphins, then it becomes the killer of sharks.

Killer whales are one-on-one heads-up and group picking, which are not inferior to sharks.

Killer whales have great strength, sharp teeth, and plenty of intelligence.

When killer whales attack sharks, they will knock the shark over, exposing their belly to it, and the shark may become stiff.

Some killer whales also attack the heart of the shark, causing the shark to suffer cardiac arrest.

What's more, killer whales will even 'karate', stirring the currents with their tails, creating a whirlpool that forces the shark to surface through lift, and then turns its body and slashes at enemies with its tail, similar to the palm slash in karate, and can even stun the shark.

But I'm no ordinary shark.

They were huge, with hard scales and thick muscles, how could they possibly knock themselves out of here.

Regardless of Xia Qiu, she swam forward with all her strength and bit a dolphin.

Click.

Xia Qiu swallowed the dolphin directly into his mouth and bit it to pieces.

The moment he was bitten, the remaining dolphins crashed into Xia Qiu's body.

Bang, bang, bang, bang.

Xia Qiu felt a force coming from the upper right side, while the dolphin on the left began to hit the lower right side.

One up, one down, forcing yourself to flip.

Really smart.

Dolphins can communicate through sonar systems and lay out tactics.

Encirclement, crossing, ramming, you can do it.

And the killer whales in it can even use themselves as bait to let themselves wash up into the shallows to attract fur seals and wait for them to come over and let other killer whales hunt.

Under their impact, Xia Qiu's figure shook slightly, although their strength was not enough to knock Xia Qiu over, but it made him stagnate.

But at this time, Xia Qiu rotated in the direction of the dolphin impact.

Rumble.

The massive figure slammed down on their second impact, and the pectoral fins also slammed down with the rotation of their bodies.

Rotate the palm split.

Rumble.

The left side hit the dolphin below him and was smashed under him.

Bang.

His pectoral fin hit a dolphin and knocked it unconscious.

Then Xia Qiu turned his body and bit the dolphin on the left, and at the moment of turning, he swung his tail, and his thick tail swept and hit two dolphins.

Bang, bang.

The dolphin was smashed straight out and flew out.

And Xia Qiu's mouth has already bitten a dolphin.

Click, click.

Summer and autumn eat dolphins, and the dolphins' actions have no effect.

But the next moment, five or six dolphins suddenly swam into the distance and pulled away.

Xia Qiu didn't chase them, and the dolphins he knocked down by himself were already enough to feed themselves

There was no need for those dolphins to chase after them.

Summer and autumn gnawed on dolphins, swallowing them into their stomachs, and their blood stained the surrounding seas red.

After eating seven or eight dolphins, Xia and Autumn reached the maximum amount of food, and it is estimated that it will take more than two hours to digest it.

Xia Qiu slowly returned to his habitat, waiting for the beginning of evolution.

。。。

"What a fish."

In the northwest of the island, on a huge rock, a girl with short orange hair sat there, she held a telescope in her hand and stared at the sea in the distance, saw the huge black fish hunting dolphins, dived into the ocean, disappeared, put down the telescope, and showed a puzzled look: "There are such big marine fish around here?" Swimmers are fast and ferocious. Not a shark, not a whale, what kind of it? ”

The girl thought for a moment, shook her head, glanced at the sky, and said, "It's going to rain, it's time to go back." ”

She got up, jumped on the rocks, left the seashore, and ran in the direction of home.
