Poisonous crabs
Recently, the reporter saw a specimen of embroidered crab containing toxins in the Hainan Tropical Biological Resources Science Popularization Museum. Its cephalothorax carapace is transversely oval, the anterior lateral margin is thin plate-shaped, divided into four leaves behind the outer eye socket, the claws are asymmetrical left and right, there are bundles of bristles, the cheek area is densely covered with fluff, and the whole body has a red and white mesh pattern, the nail length is about 4 cm, and the nail width is about 8 cm.
Huang Shengzhuo, an associate researcher at the Institute of Tropical Biotechnology of the Chinese Academy of Tropical Agricultural Sciences, said that the embroidered ridge ripe crab is the most poisonous crab known, they often live in the rock bottom or coral reef bush from the low tide line to the water depth of 30 meters, and some of them contain pufferfish poison, some contain paralytic shellfish poison, and some contain anemone poison. The toxins in an adult embroidered crab can poison 45,000 mice and dozens of people.
Huang Shengzhuo introduced that there are currently five or six kinds of poisonous crabs common in Hainan, and the upright love crab is one of them. Although the name of the upright love crab is very "upright", its body can produce tetrodotoxin and is not suitable for consumption. The upright crab carapace is wider than the nail length, the surface is raised, and the partition is unknown. The anterior lateral margin is thinly plate-shaped, convex outwards, and the posterior lateral margin is concave. The claws are thick and large, and the back of the palm joints is rounded and blunt. The foot is wide and flat, and the body color is uniform orange yellow to orange red.
With the integrity of the love crab belongs to the same fan crab family of fine lines love crab, pattern love crab body also contains toxicity, although the toxic content is low, but it is not recommended to eat, eat a certain amount will affect the human body. "Different toxins act and react differently to people with different constitutions. Fungal heating may eliminate toxins, but toxin heating in crabs cannot eliminate them, so these crabs are best not to eat. Huang Shengzhuo said.

Dangerous snails
The shells of the family Woven Snail are generally small, conical spiral towers with rounded shell bottoms. Shells are generally smooth and shiny, and some have spiral ribs. The anterior water pipe groove is short and wide. The upper jaw of the outer lip has small teeth. The shape of the weave snail is characterized by a pointed tail, slender, about 1 cm in length and about 0.5 cm in width, about the size of a fingernail.
Weave snails generally live near offshore reefs and on sediment floors. The snail itself is non-toxic, and its deadly toxicity is obtained in the growing environment, and it is poisoned by eating toxic algae, enriching and accumulating algal toxins, or other toxic substances such as tetrodotoxin. The main toxin causing food poisoning by snails is paralytic shellfish toxin, similar to tetrodotoxin, and poisoned people mainly have symptoms of neuropathic paralysis and high mortality.
Chicken heart snail, also known as "taro snail", mainly grows in tropical seas, generally living in warm seas, coral reefs and beaches of the South China Sea islands are distributed.
The reporter saw the chicken heart snail specimen in the Hainan Tropical Biological Resources Science Popularization Museum, the front of the shell is sharp and thin and the back end is thick, shaped like the heart of a chicken or taro, the surface has a pattern, and the shape is very good. According to reports, the chicken heart snail is a marine creature that contains high poison, because its tip part hides a small opening, which contains poisonous teeth that can shoot out venom, enough to kill people. The poison of the chicken heart snail can make the victim itch and scratch, and it is impossible to do anything for a short time, and the toxin may cause the victim to be completely paralyzed.

goby
Most fish are edible, but gobies are eaten with caution. According to Zhang Zelong, deputy director of the Tropical Marine Living Resources Exhibition Hall, goby is a collective name for various gobies in the gobies family, and is a small carnivorous fish. Each of them has its own characteristics, such as "pygmy goby" and "common goby", etc., is the largest family of fish, known to more than 2100 species. They appear short, only a few centimeters long, have two vertebral fins, and mostly inhabit tropical waters, making them a favorite food for coastal dwellers. However, some species have pufferfish poison, ciguatera toxin, and especially cloud-spotted bare-cheeked goby, which can be fatal when eaten with 2 tails.

Blue-ringed octopus
The blue-ringed octopus belongs to the octopus family, commonly known as the blue-circle octopus, which is only the size of a golf ball, with an arm span of no more than 15 centimeters, but secretes enough venom to kill people in a single bite. Since this venom does not yet have an antidote, the blue-circled octopus is one of the most venomous marine organisms known. Its sharp mouth is able to penetrate the diver's wetsuit. The body surface is yellowish brown and it is easy to hide from the surrounding environment.
According to reports, people have almost no pain after being stinged by this octopus, and the toxicity begins to attack after an hour. But these octopuses don't actively attack humans unless they are greatly threatened.

Rose poison scorpion
The rose poison scorpion is ugly in appearance and is like a stone when lurking, so it is also called "stone fish". When its fins open, two large red spots can be seen, similar to the color of roses. Its body color is varied, often similar to the color of the surrounding environment.
After a person is stabbed by a rose poisonous scorpion, the wound is partially whitish, and the body will produce acute and severe labor pain, such as burning and whiplash, which is unbearable, so that it loses consciousness or even dies.
