Precautions for diving Why can't you touch marine life when diving?
Diving is a popular recreational adventure at present. Accompanied by professional diving instructors, many people quickly learned to dive, so that they can sneak freely in the underwater world and watch the wonderful underwater world, all kinds of beautiful creatures and ecosystems. Let's share with you why diving can't touch marine life.

After working in Bali for 9 months, I haven't been to several diving spots in the north of Bali, and the rest are familiar with it. Of course, I have seen this kind of coral with my own eyes.

All right, let's not digress. Why can't you touch underwater creatures?

1. The most important thing is danger!

Whether you intentionally or unintentionally, underwater creatures can easily hurt you. To exaggerate, almost all the seabed is toxic, but the toxicity is different.

There are too many poisons. Let me give you some of the most common:

Lovely class:

Do you think the little sea rabbit is cute?

It looks so soft. Why can't you feel it?

The poison gland of the sea slug is in the front of the mantle, which can secrete a slightly acidic milky liquid with an unpleasant smell. If the other party comes into contact with this liquid, it will be poisoned, injured or even killed. So the enemy will stay away when they smell this smell. This is a chemical weapon against the enemy. See you manually.

Intense class:

There is a hole here. Uh, reach in and dig. Is there any treasure or something?

Where is the video of the big moray eel eating sharks?

Did you see his teeth? It's the sawtooth of big steel. Bite it down, and the front long incisors bite directly into the bone. I saw a foreigner's calf bitten with my own eyes. The bite marks are not obvious, just a few small holes, but the wound is particularly deep, and the blood keeps flowing out and can't stop.

Finally, the ambulance came, still bleeding.

Novice killer class:

Oh, I just learned to dive. I am not neutral. What should I do if my knees and hands are always grabbing things?

You touch it, and no one stops you. Especially dead sea urchins, some waves turn sea urchin shells into shallow sand piles. Touch your palm if you don't pay attention. Cool!

Divers who study AOW should pay more attention to sea urchins, which are Nocturnal Animals. They all come out to feed at night. Even if you poke the trunk with a 20 cm long thorn and pull it out, the tiny burr will be inside, which is almost invisible when you dial it with a needle. Sea urchin toxin will make your wound red, itchy and painful.

Treatment: Most sea urchin toxins are alkaline. After being pricked, in addition to pulling out the trunk, you should also apply lime juice to the wound. Lime is a kind of flavored fruit in Southeast Asia, which is very sour. At this time, it is used to neutralize sea urchin toxins. Of course, you must apply it very hard, otherwise the orange juice will not penetrate into the wound. Imagine that there are thorns under the skin, but when you press it hard, it feels sour and cool.

Invisible class:

I just like walking around. I think it is safe to hold the stone.

Stone fish will give you an encyclopedia:

Chinese name rose poison _

Stone fish is a kind of fish with strong toxicity in nature, and its "deadly sting" is described as the most painful sting of human beings. The stone fish is not surprising in appearance, only about 30 centimeters long, and likes to hide under the sea floor or rocks and disguise itself as an inconspicuous stone. If someone does not pay attention to stepping on it, it will immediately fight back rudely and release deadly venom. The backstab from 12 to 14 on its back, as sharp as a needle, will easily penetrate and pierce the soles of the feet, causing people to be poisoned quickly and remain in severe pain until death.

I saw it once in the Philippines, eh! Thumb swollen like a wrist, rolled all over the floor, covered in sweat. I finally fainted from the pain. I saw it once in the Philippines, eh! Thumb swollen like a wrist, rolled all over the floor, covered in sweat. Finally, if you feel dizzy, don't scratch underwater. I thought it was a stone, but I was stabbed. It really hurt.

Scorpion fish:

Often perches on the rock wall in the sea, like an ordinary stone. Its predation mode is very interesting, and it often waits for the arrival of food by waiting. Its hard spines (the poisonous glands at the base of dorsal fin spines are neurotoxic) are fatal and highly toxic.

Scorpion fish, like stone fish, are almost indistinguishable except for experienced divers. Some people say that stone fish is scorpion fish, but it is not. The two are similar, but they are actually two kinds. The stone fish is round, with its mouth down and unhappy.

Face. Scorpion fish has a long body, cheeks like wings and a trumpet-shaped mouth. But no matter what kind of fish it is, it is highly toxic. Do not touch it!

Coral:

No, no, neutrality is not good again. Get your hands off me!

Fire coral, also known as spiny coral, is commonly known as dichotomous thousand-hole coral. It belongs to jellyfish and contains highly toxic spiny hyphae. If you touch the fire coral, the skin will feel burning immediately, and a rash will appear at the same time, which will lead to swollen lymph glands.

I was stung and felt like an electric shock. First I was pricked by a needle, and then I sweated underwater. After being underwater for about a few minutes, the pain stopped and I began to itch. After landing, it was like a fire, itchy, swollen and painful. Finally, it becomes a hard pimple like calluses. It feels good ~

His horror is that sometimes the wind and waves are bigger, the full moon ebbs and flows, and some debris floats in the water. You don't touch anything at all, but you feel suddenly charged, much like a jellyfish.

Treatment: Rinse with seawater, then wipe the affected area with vinegar or alcohol to relieve the pain, finally pull out or take out the residue with tweezers, apply antihistamine and other drugs on the affected area to relieve itching and burning sensation, or use painkillers.

So apart from it, ordinary corals will be fine? You are so naive. After being scratched by coral, it is not as violent as fire coral, but it is also itchy.

This is the so-called common coral, which has been stung before.

Small shellfish:

Wow! What beautiful shells! Grab one and put it at home!

Encyclopedia: Cone

Snail), also known as "conus", mainly grows in tropical waters and generally lives in warm waters. It belongs to molluscs, gastropods and conodontidae. This is a beautiful snail that lives on coastal coral reefs and beaches. The shell of the chicken heart snail is sharp at the front and thin at the back, which looks like a chicken heart or taro. It is a highly toxic marine creature with various kinds, colors and patterns, because its tip part hides a small opening with fangs, from which venom can be injected, enough to kill the injured.

Are you still catching it?

Fatal temptation class:

Wow! This fish is so beautiful, like a soldier waving a flag!

Lion fish:

Inhabits on rocks or corals, and some live in deep water. Often swim in pairs, and when they meet the enemy, they sprint sideways with dorsal fin spines. Fin stings have poisonous glands, which cause severe pain after being stabbed, and even lead to dyspnea and syncope in severe cases.

But the lionfish moves slowly, so don't provoke it, it won't attack you.

Let's talk briefly about these creatures that are easy to hurt people when diving in Southeast Asia, not to mention jellyfish. As we all know, jellyfish must be very sour. How sour is it? According to my folk survey, the coaches who have been attacked by various creatures at home and abroad are the most injured.

2. Ecological protection

Coral is the cradle of fish. During the spawning period, big fish will spawn in coral bushes. After hatching, small fish will avoid the predation of big fish and grow here. It can be said that the diversity of underwater species in this area depends on the health of local corals.

But corals are fragile and grow very slowly. With the increase of global temperature, a large number of corals in some shallow seas die, coupled with the destruction of the environment by human beings, more and more beautiful underwater scenery is gradually declining.

Even now, many divers who have been diving for a long time are saying that the real diving is only 20 years at most. With more and more divers, the natural scenery is gradually declining, so everyone should protect and contribute to the underwater environment.

What should I pay attention to when diving?

When some bacteria on human hands contact and destroy coral, it will cause serious harm. Once the coral is damaged, the outer barrier will lose its protection. If contaminated by other bacteria, it will gradually turn white from the damaged area and slowly erode the whole coral like cancer.

Sunscreen is also deadly to corals. Chemicals in sunscreen will directly inactivate corals, so it is recommended to buy special diving sunscreen to contribute to environmental protection.

It is gratifying that more and more divers are taking part in protecting the marine environment.

So try not to touch anything underwater, and leave nothing but photos and bubbles.
