How do basking sharks hunt for food?

Scientists and marine biologists discovered that the way the basking shark eats is very magical, that is, to open a big mouth and wait for the food to swim into its mouth by itself.

Basking sharks have huge olfactory bulbs in their bodies that can guide their prey in the "right" direction. The basking sharks swallow a little when the food enters their mouths. In addition, they will not actively hunt their prey.

Xiang Yang tried to swim towards the basking shark. The basking shark is a passive filter-feeding animal. It can filter plankton, small fish and invertebrates from 2000 seawater per hour. They swim slowly. When he pushes the sea water into his gills, Xiang Yang will not be in any danger near this basking shark.

Xiang Yang swam very fast, and after a few flashes, he swam near the basking shark.

After seeing Xiang Yang, this basking shark closed its mouth, staring at Xiang Yang curiously with its small mung bean eyes. They do not attack humans like great white sharks, nor do they avoid humans like fin whales.

Basking sharks do no harm to humans, nor will they be lured by the bait thrown by humans.

Xiang Yang reached out and touched the skin of the basking shark. The flesh was very tight and the skin was very elastic. It was obvious that its muscles were very developed.

"This should be a basking shark that has just grown up and hasn't found the group yet." Xiang Yang secretly said.

Basking sharks have a very speechless habit, that is, basking sharks are generally living creatures that separate males and females and move in groups.

This means that in a large group of basking sharks, all males are males, and all females are females. There may be several male cubs in the female basking shark group. Once the male cubs become adults, they will leave immediately. Group of female basking sharks.

The number of basking sharks is uncertain.

At the least, there are groups of three to five, and there are also very large groups of basking sharks. There are more than one hundred basking sharks in a mighty group, which are simply living ocean vacuum cleaners.

This basking shark seemed to be very uncomfortable with Xiang Yang's petting. The moment Xiang Yang put his hand on it, it swung its huge body and retreated back.

A pair of small mung bean eyes are crowded together, staring at Xiang Yang curiously.

Xiang Yang felt a little funny, stretched out his hand and waved at the granning shark.

Xiang Yang knows that this basking shark can definitely see itself waving, because although the basking shark’s eyes are smiling, they are well developed. Their eyes are like the sense of smell of a dog, they can see far away and can see through. To confirm whether the passing ships have seen them before.

Basking shark saw Xiang Yang waving his hand, thinking that Xiang Yang was going to hit him, and quickly stepped back.

Regardless of the huge body of the basking shark, in fact they are in a very awkward position in the marine food chain.

From the point of view of the prey creatures, they belong to the very lower marine predators in the marine food chain pyramid.

However, there are not many creatures that can prey on basking sharks. The only ones that have been discovered are killer whales and tiger sharks.

Dolphins and eels are also often attracted to basking sharks and like to catch up and bite the basking sharks.

However, even if the dolphins and eels catch up with the basking shark, they generally cannot kill the basking shark. Because the skin of the basking shark is very tight and very thick, it cannot be separated by the dolphins and eels.

Xiang Yang didn't plan to hunt this basking shark.

Although basking sharks were once the main harvest of fishermen in the history of fisheries, they have a very wide range of commercial uses. The body can be made into canned fish or fish meal. Fish skin is the best leather material, made of basking shark skin. His belts, leather jackets, and boots were once included in the scope of luxury goods.

In addition, the fin of a basking shark is the raw material of the well-known Jiutian shark's fin. The price of this gadget is absolutely priceless.

There is a boss in Hengdian who has a set of nine-day shark fins. Since 2005, he has been renting them to various crews as props for filming. Now almost 20 years have passed, and he is still not willing to eat it.

Xiang Yang looked at the fins of the basking shark and sighed in his heart. The basking shark was killed in large numbers because of this fin. In recent years, it has been almost extinct because of overfishing.

After the International Union for Conservation of Nature listed basking sharks as one of the “endangered organisms”, many coastal countries in the world have issued laws to protect basking sharks. my country is also restricting the trade of basking shark products, especially in the past few years. Many of the superstars have filmed public service advertisements that refuse to eat shark fin, and there is no harm if there is no killing.

This basking shark has little courage, more than four meters in length, but still afraid of Xiang Yang, who is less than two meters in length.

His mung bean-like eyes kept staring at Xiang Yang, and then his body kept backing away.

When Xiang Yang saw it, he no longer had the desire to catch up. He quietly watched the basking shark swim backwards for a certain distance, then swam away with its tail, and then folded back towards the original. Lufan swims back.

When Xiang Yang swam back, there were no crew members in that sea area, and they all got on the deck.

Every half an hour of diving, you must go on board and rest for a while. This rule has now changed from the rules Xiang Yang set for the crew to the tradition of Xiang Yang's fleet. Everyone consciously abides by, strictly enforces them, and reminds each other.

Xiang Yang swam quietly under the boat, then surfaced, and climbed onto the deck through the suspended ladder in the boat book.

When Chen Qingsheng saw Xiang Yang getting on the boat, he walked to the side of the boat and stretched out his hand to hold Xiang Yang. He smiled and said, "Captain, you have been on the boat for a long time this time. What good things have you gotten?"

"I didn't catch anything." Xiang Yang smiled and patted the empty net bag around his waist. "I didn't actually go down for long. I went to the deck and let you know about the starfish and shrimps~www.readwn.com~ wait until I Ten minutes passed after all the notifications. In fact, it took me only ten minutes to go into the sea."

Fang Youqun looked at Xiang Yang with a weird look, "Brother Yang, do you actually come up empty-handed?"

It's no wonder that Fang Youqun is strange. In the past, Xiang Yang caught the most fish by himself every time Xiang Yang went to the sea. This time Xiang Yang went down for more than ten minutes and he didn't catch anything.

"There are a lot of marine products under the water." Fang Youqun counted as if breaking his fingers, "starfish, starfish shrimp, fluttering fish, large lobster, swimming crab...You can't just turn around, Brother Yang. You can't get anything in a few minutes, right? You can't get anything. It's good to pick up a few scallops."

"Piaopiao fish, ribbon conger eels, and starfish shrimps were all found by the captain." Chen Qingsheng squinted at Fang Youqun. "Do you think the captain just needs to fish up a few marine products like you? He has found these things more credit than you. It’s a big deal to catch a hundred catties of seafood. Without him, I will put the starfish shrimp and floating fish in front of you, do you know?"

"Uh."

Fang Youqun let out a uh, he looked at Xiang Yang awkwardly, "Brother Yang, have you been looking for something good again?"
