"Don't be reluctant to give me up, but I think it's safer for you to hide in the seaweed."

Tang Hai looked at the little leopard print and turned back one step at a time, and thought that the little guy was reluctant to himself, so he waved his hand.

As a result, the baby leopard shark swam back!

"Oh, I didn't mean to beckon you back, okay, hug, scratch." Tang Hai picked up the little leopard shark again and scratched its belly.

This thing is very squeamish, like the leopard shark in the French aquarium, the staff wears a diving suit to go in to clean the glass, and a few of the ones that have been raised will hit him, begging to tickle, and even sell cute performances for this.

If it is a group of leopard sharks living together, the older ones are like the big brother in the bad boys, taking a group of little children to the coral reef to find food, and the small ones are inexplicably following, in fact, the little leopard sharks probably don't know what to do, they are used to following the older children......

Others are similar in size and benthic to others, and live with the same fish that are mainly nocturnal, and even if they look different, they feel that they are their own compatriots.

Tang Hai thought that this little guy regarded himself as a compatriot, the balls were a little painful, and he looked like a fish?

Hug again, scratch again.

"Okay, you go play, I'm still busy." Tang Hai didn't care if the little guy could understand it or not, and waved his hand to let it play its own.

The little guy walked again, but when he was about 20 meters away, he turned back to look at Tang Hai.

Tang Hai finally reacted at this time, the little guy wanted to let himself go with it!

"Ouch, I had a lot of bad luck when I was active as a human being, either I ran into a porcelain, or I met an uncle who beat someone, followed by a bear child, and there was a person who asked me for money every day...... But as soon as you transform into an ocean body, luck is bursting! Could this be the return of the legendary fish! ”

Tang Hai hurriedly transferred the things in his hand to a beach by the sea, and then followed the leopard shark to swim to the deep sea, already wondering if he was planning to take himself to a shipwreck or something like that......

As long as it is within the range of the Tang Sea's oceanic body, where is there a shipwreck. Tang Hai can feel it directly!

However, it's basically worthless rotten wood, or it's simply something that has been dived and retrieved, even if you get it. It is also suitable for making firewood for fire, and it is better to keep it as a home for small marine creatures!

Tang Hai thought about the cat's repayment, the clam shell girl and other strange things, and swam with the little leopard shark, and he didn't know where this thing was going to take him.

The leopard shark swayed in front, and soon Tang Hai sensed that something was wrong. Because it's already in the deep waters!

The reason why people often encounter leopard sharks at the beach is because these little guys are not good at diving and prefer to eat small scallops near the reef in shallow waters, and that kind of place is a place where tourists like to dive and sightsee.

But now at this water level, the temperature has reached below 15 degrees Celsius, as long as it enters 13 degrees Celsius, it is the cold water temperature position!

It was a slope of a few tenths of an angle before, and suddenly there was a big steep slope, and the little leopard shark entered without the slightest hesitation.

Tang Hai did not have a phobia of density, and cleaned up the dense barnacles for the big-finned whale before. He can only get excited.

But to be honest, he has a phobia of the deep sea! This kind of sudden deepening place, he will be uneasy!

"Keep up! I'm afraid of a ball, this is still my sphere of influence, I can play blue whales! Tang Hai paused and followed.

In the end, I walked like this for an hour, and I don't know how much depth I reached, but it was probably more than 500 meters deep......

Suddenly, Tang Hai's body was shocked!

The position where he was standing now was about the mountainside on the land. Looking down, there is a coral grove below!

The water temperature here is about 7 degrees Celsius......

The optimal living water temperature is 4 to 13 degrees Celsius, the growth is slow, and the average density is 2.8. Instead of 1.8 in the shallow sea, known as the real marine treasure, it can only grow one centimeter in more than ten years, and the treasure is sold by the gram, which has a huge effect on the nutrient water body......

Cold-water corals!

Some are as tall as mountain peaks, reaching a maximum of about ten meters. Four floors!

There are antler-shaped quadruple forks!

There are clouds like clouds!

And it looks like aloe vera grows open!

Tang Hai didn't know the exact species of cold-water corals, but he could at least see the different species, there were at least twenty kinds of corals here, one of them in the past, covering maybe half a kilometer away!

Coral is a treasure of the sea, and whether the water quality is polluted or not is actually just a matter of looking at the coral.

In 2011, the Fukushima nuclear leak caused the coral around Fukushima to die, and at the end of 2013, the initial sea control was successful, the coral death was contained, and the Olympic bid was passed, and then in 2014, the food radiation monitoring near Fukushima was relaxed, and only in the coral death center area and a few nearby areas still maintained the highest detection standards.

The easiest way to tell if a place is overpolluted is to look at the corals there!

Of course, some places where there are no corals in the first place don't count......

Because Japan is a red coral production area, it was clear that only one area reached heavy pollution that year, and as a result, red coral merchants spread rumors that all the corals in Japan's waters are hanging and are the last treasures of Japan. In fact, just listen to this thing, Tang Hai hears every year that all corals in Japan are hanging, and it is estimated that the corals hung up in Japan are several times more than the global coral reserves......

Because of the hype, it was in 2011 that the price of red coral suddenly skyrocketed and became a super hit! Until now, the heat has not disappeared!

This thing looks like a lot, one by one, but where the water depth exceeds 500 meters, with the current methods of human beings, it can only be explored point by point, and it is normal that it cannot be found.

For example, in 2007, scientists at Memorial University of Newfoundland in Canada discovered a large area of cold-water coral from the Hudson Strait to the southern part of Newfoundland, and then applied to the Northwest Atlantic Fisheries Organization for protection.

It was the world-famous 'Newfoundland Fishing Ground', which was developed at least ten times more vigorously than Washington State, and it was discovered by chance.

There are cold-water corals here in Washington State, and it's also possible!

Why are the fisheries in Norway and New Zealand so fierce?

Because they are at a depth of 6,000 meters, there are a lot of cold-water corals! Just one coral grove can reach hundreds of square kilometers!

Unlike tropical corals, not every species requires zooxanthellae symbiosis, so it can grow at great depths without the need for sunlight.

In addition to the cold-water coral, there is also the skeleton of a large-winged whale! I don't know how many years I've been dead, but it's excellent food for many scavenging sea creatures!

I heard that there are at least 850,000 giant whale carcasses on the bottom of the sea that have not decomposed, and this is the first time Tang Hai has seen it!

From plankton to tubeworms and some cephalopods, there's a light of life everywhere!

More than a dozen leopard sharks swim chasing small fish, and this is a coral paradise for these leopard sharks!

It turned out that the little guy just now was not lost, but maybe when it was raining in Tang Hai, he followed the cephalopods and found the seaweed jungle. It's now taking itself home as a guest.

"I don't know if there are any precious corals, but even if they are average, the combined value of these must be more than ten dahlias......

Tang Hai was still startled, and suddenly something touched his foot.

Tang Hai lowered his head, and the little guy bit something and put it at his feet.

Stone scallops, a native of Washington State, are they a return gift for yourself?

Tang Hai bent down to pick up something, and the little guy pounced on him, twisting and asking him to help scratch his belly.
