The seabed is a mysterious world. Human beings have their own protection and defense systems, especially the underwater creatures. And you can easily get hurt if you are not careful. Even experienced divers cannot avoid it sometimes. Therefore, you must listen to the instructor's advice when traveling for diving. Don't be fooled by the cute species on the seabed. The more charming the more dangerous the species is. Describe the underwater world! Stonefish: Chinese name: Rose Poison_

The stonefish is a very poisonous fish in nature, and its fatal sting has been described as the most painful sting to humans. The stone fish is not amazing in appearance, only about 30 centimeters in length. It likes to hide on the seabed or under rocks, disguising itself as an inconspicuous stone. If someone steps on it accidentally, it will fight back immediately and emit deadly poison. The 12 to 14 needle-like back spines on its back will easily penetrate the thorns on the soles of shoes. Entering the soles of the feet, the person is quickly poisoned and remains in severe pain until death.

I saw it once in the Philippines, eh! The big female’s fingers were swollen as big as her wrist, she was rolling all over the floor and sweating all over her body. In the end, it hurt and fainted. Everyone was frightened on the spot. When they heard that they were still breathing, they breathed a big sigh of relief. The scariest thing about this thing is that it's very difficult to identify it, so don't grab it underwater (I say this with all sincerity). I thought it was a rock, but when I was stabbed, the pain was really overwhelming. Scorpion fish

It often lives on rock walls in the sea, just like an inconspicuous stone. Its hunting method is very interesting, and it often waits for food to arrive. Its hard spines (the venom glands at the base of the dorsal fin spines are neurotoxic) are deadly poisonous.

Scorpion fish, like stone fish, are generally almost indistinguishable except to experienced divers. Some people say that stone fish are scorpion fish, but they are not. They are similar, but they are indeed two types. The stone fish has a round body, downward-facing mouth corners, and an unhappy

face. The scorpion fish has a long body, two gills like wings, and the corners of its mouth expand outward. But no matter what kind of fish it is, it is highly poisonous. Don’t touch! Small shells

Encyclopedia: Cone

Snail is also called cone snail. It mainly grows in tropical seas and generally lives in warm seas. It belongs to the phylum Mollusca. Gastropods, Cone family, are beautiful snails that live on coastal coral reefs and beaches. The cone snail shell is thin at the front and thick at the back, shaped like a chicken heart or a taro. There are many types of it, with different colors and patterns. It is a highly venomous sea creature because its tip has a small opening hidden in it with fangs from which venom can be ejected, which is enough to kill the injured person. Lionfish

The body length is 25-40 centimeters, and it is a general name for fish belonging to the order _forma_family_lionfish_. The typical feature is the large fan-like pectoral fins. Feeds mainly on crustaceans. It is mostly found in rocky or coral reefs near the coast of the temperate zone. It is distributed in the warm waters of the Indo-West Pacific. It is a small marine fish.

They inhabit rocks or coral thickets, and some are found in deep water. A very dangerous fish, not only dangerous to small fish, but also a threat to humans. The sting on its dorsal fin is very poisonous. When encountering an enemy, it turns sideways and sprints toward the opponent with its dorsal fin spines. The fin spines have venom glands, which can cause severe pain after being stung. In severe cases, people may have difficulty breathing or even faint. Fire coral

Fire coral is a polyp of the Milleporidae family (Milleporidae or Milleporidae). They look like coral, but they are not actually corals, but are closer to jellyfish and sea anemones. If accidentally touched, the skin will feel like a fire. Due to low recognition, accidental injuries caused by fire corals are very common among divers, so divers with poor neutrality must stay away from them.

The blue-ringed octopus with rings on its body

Also known as "blue-ringed octopus" and "leopard octopus", it is a species that lives on the west coast of the Pacific Ocean and is distributed from Japan to Octopus is found in Australia. ***With three extant species and one unidentified species, the blue-ringed octopus is one of the most venomous animals in the world. The unknown creature floating on the water - the man-of-war jellyfish

I don’t need to say more about the man-of-war jellyfish. If you still want to dive and breathe air in this life, just stay away from it. At that time, I was watching an episode of "Blue Planet 2", in which a man-of-war jellyfish was filmed using its tentacles to prey on small fish. Any small fish that touched its tentacles would be killed instantly. Cute sea hare

Speaking of the sea Rabbits, many people don’t know that they are also poisonous.

Especially the colorful sea hares, which are produced in the Indian Ocean to the Pacific Ocean, have obvious naked gills, changeable body colors, and unique appearances. They are species with extremely high ornamental value. However, these species are mostly toxic and will release toxins to protect themselves. This species only There are a small number of vegetarians, most of whom are carnivores. Lack of nutrients will cause the rabbit to shrink, lack vitality, and die. The bird-tailed mantis shrimp with amazing attack power

The bird-tailed mantis shrimp is also called the bullet mantis shrimp. There is also this thing, the bird-tailed mantis shrimp, which comes with a cool and warm color gradient aesthetic armor. It looks silly. The shrimp is also called the bullet mantis shrimp. It belongs to the same order as the Pipi shrimp. It must be the most ferocious shrimp in the world. How amazing is its attack power.

The bird-tail mantis shrimp can eject the front end of its catching limb in one-fiftieth of a second, with a maximum speed of more than 80 kilometers per hour, an acceleration exceeding 0.22-inch caliber pistol bullets, and can produce up to The impact force of 60 kilograms and the high temperature generated by friction can even cause electric sparks to appear in the surrounding water. A scientist once hurt his finger while wearing gloves when he went into the sea to catch it, causing it to bleed. He took it back to the laboratory and put it in a measuring cylinder, which was also shattered by the blow. Touching the sea will affect the survival of marine life

1. Some bacteria on human hands will cause serious damage to corals when they touch or damage them. Coral polyps only exist in a thin outer layer of corals. , once damaged, the outer barrier loses protection. If it is contaminated with other bacteria, it will gradually bleach from the damaged area outwards, slowly eroding the entire coral like cancer. So when someone touches a parrotfish, or hugs a grouper for a selfie, it removes much of the protective coating.

2. Although it may not cause any big problems in the short term, it can be clearly concluded from some cases that some groupers are easily infected by parasites after being tamed in aquariums. Although divers often clean them up, their skin still has obvious wounds and some parasites.

3. The above are only a small number of creatures that can cause varying degrees of harm to us, but every diver should remember that even if it is not for yourself, even if you know that the creature you want to touch is harmful to us, You pose no threat or harm, and you have to remember that one of your unintentional actions may cause them to die. Everyone should be able to remember the beautiful scene that made us choose to become divers. I don't want our descendants to have to know a creature that now appears in front of us and amaze us only through television, and I know you think so too.

4. Coral is the cradle of fish. During the spawning period, big fish will lay their eggs in the coral. After hatching, the small fish will avoid predators from the big fish in the coral and grow here. It can be said that the diversity of underwater species in a region depends on the health of local corals. But corals are fragile and grow very slowly. As global temperatures rise, corals in some shallow sea areas die in large numbers, and as humans damage the environment, more and more beautiful underwater scenery is gradually declining. Even many divers who have been diving for a long time now say that real diving can only last for 20 years at most. With the large increase in divers, the natural scenery has gradually declined, so everyone must protect the underwater environment and make a contribution to the underwater environment. How to protect underwater life while diving

1. Maintain proficient diving skills

The first way for divers to avoid damaging coral reefs is to maintain good neutral buoyancy. Insufficient buoyancy will crush the coral and harm the organisms below it. Excessive buoyancy will cause the diver to hold on to the coral or certain objects, which may cause damage to the coral. Try to keep your body in a horizontal position when diving. If the body moves forward in a nearly vertical pattern, it can easily kick up corals and stir up sediments on the seabed.

2. Never try to squeeze through a small place

Divers sometimes fail to realize that the width of their body has increased after putting on the tank, but they still try to swim through the rocks. If you go through a narrow gap or a small hole, you will encounter various sponges, soft corals and small creatures attached to the stone surface, causing harm to the other party.

3. Tighten additional equipment to prevent it from being dragged

Additional equipment such as gas meters, backup air hoses, flashlights, etc. should be close to the diving suit to prevent them from being dragged around corals and other Drag on vulnerable creatures. Even perfect buoyancy control can't prevent damage to corals when towed by untethered equipment.

4. Once entangled, do not force your way out

When you are snorkeling at the bottom of the sea but suddenly cannot swim forward, many divers will panic. In fact, this is usually just because of something. Some equipment is caused by coral hooks. You only need to stop and slowly free yourself from the hook, or ask your diving buddy for help. This way you can not only reduce the unnecessary consumption of gas in the cylinder, but also cause less damage to the environment. of destruction. Trying to break free will only make the situation worse!
