1. What are the benefits of octopus?

Octopus, also known as eight-clawed fish, eight-clawed octopus, etc., is a cephalopod, Octopus, Octopus family (Octopidae):

1. Short octopus: Octopus ocellatus Gray Common name: Eight-tail octopus, rice octopus, eight-tail fish, octopus. The body is oval or spherical, without fleshy fins. There is a spindle-shaped or half-moon-shaped patch between the two eyes on the back of the body, and there is an oval golden circle in front of each eye. The arms are short and of similar length. The third arm on the right side of the male is stalked, and the sperm groove is formed by the side membrane of the arm. The body is yellow-brown, and the inner shell is degenerate. It is a benthic carnivorous species distributed in various sea areas of my country.

2. Octopus variabilis (Sasaki) is commonly known as long-legged octopus, horse octopus, and octopus. The body is long and oval, without fins, with smooth skin and no plates or golden rings between the eyes. The arms are long and the lengths vary greatly. The first pair of arms is the longest, twice the length of the fourth arm and six times the length of the head and body. The inner shell is degenerate. It is distributed along the southern and northern coasts.

3. Octopus ovulum (Sasaki) The body is oval, each arm is equal in length, and each arm has two rows of suckers. The third arm on the right side of the male is stalked. It lives in the muddy and soft muddy seabed at a depth of 20-180m. It is distributed in the East China Sea and the South China Sea.

4. Octopus vulgaris Lamarck: The body is oval, with sparse warts on the back surface, long arms, equal arms, and the third arm on the right side of the male is stalked. The body is brown when alive. The inner shell is degenerate. Distributed along the southeast coast.

The above species have delicious meat and ink sacs that have a hemostatic effect. Zhejiang once produced ink capsules for women with functional uterine bleeding and various bleeding diseases. The whole body is used as medicine, called octopus. It is rich in protein, amino acids, fat, ash and active toxins. It has the functions of replenishing qi and blood, regulating menstruation and promoting lactation, and is used for chronic illness and physical weakness, postpartum milk deficiency, etc. Pharmacological experiments have shown that octopus toxins can reduce the heart beat amplitude of crabs, bridge and stop beating in the diastole, increase the contraction amplitude of the rabbit's duodenum, and inhibit the respiratory system. It also has an inhibitory effect on sarcoma 180.

2. Can octopus claws suck human blood?

First, the octopus’s arms are called tentacles, not claws.

Second, octopuses are not bats or mosquitoes and do not live by sucking blood.

Third, there are suction cups on the tentacles to suck prey. You can think of them as cupping cups. They suck on your skin to rupture your capillaries and cause bleeding.

3. How do octopuses protect themselves when they are in danger?

Whenever an octopus encounters an enemy, its tentacles are sometimes firmly grasped by the enemy. At this time, it will automatically throw away the tentacles and step back, letting the broken tentacles wriggle to confuse the enemy and take the opportunity to slip away quickly. Whenever a tentacle is broken, the blood vessels at the wound will contract vigorously, causing the wound to heal quickly, so the wound will not bleed, and it will heal the next day, and new tentacles will grow soon.

Octopuses can not only spray ink six times in a row, but also change their color and structure like the most flexible chameleons, becoming like a stone covered with algae, and then suddenly pounce on their prey without the prey having time to realize what is happening. Octopuses can use their flexible arms and legs to crawl between reefs, cracks and seabeds, sometimes disguising themselves as a bunch of corals, and sometimes as a pile of shiny gravel. Mark Norman of the University of Melbourne, Australia, discovered in 1998 in the estuary waters near Sulawesi Island, Indonesia that an octopus can quickly mimic poisonous creatures such as sea snakes, lionfish and jellyfish to avoid being attacked.

An octopus named Maginnetus was photographed in the tropical waters of Indonesia. It is about the size of an apple. When facing danger or encountering divers, this octopus will bend and fold six of its eight "claws" upwards to make a coconut shell look, and the remaining two "claws" will stand on the seabed and move backwards secretly, like a small coconut that can move. It escapes by walking backwards in a very funny posture. Another walnut-sized octopus, Aiculites, also walks on two feet, but the other six feet are stretched outward to simulate the appearance of seaweed.

4. Is there any serious problem if an octopus bite causes bleeding?

After the bite, the pain is like being stung by a scorpion, and the wound will swell up. It is accompanied by symptoms such as weakness and dizziness, which can last for several weeks.
