How about shark miner
shark coin is a kind of counterfeit coin, which is named sharkcoin in English, or sak for short. It was born on April 26, 2014. Sak is a super secure hash operation based on nine rounds of six encryption algorithms (Blake, BMW, groestl, JH, keccak, skein). It is suitable for CPU mining and generates a block every 20 seconds, with a total amount of 400 million
bitcoin is the ancestor of encrypted digital currency. Bitcoin is a consensus network, which promotes a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.
the sharpest organ of sharks is their sense of smell. They can smell blood and other tiny substances miles away and trace the source. They also have a sixth sense - inctive electricity, by which sharks can detect a weak electric field several feet around an object. They can also feel the vibration caused by fish or animals 600 feet away by mechanical feeling
sharks can proce thousands of teeth in their lives< Many sharks, including great white, have rows of sharp teeth in their mouths. As long as the front teeth fall off e to eating, the rear teeth will be filled. New teeth are bigger and more rable than old ones. Sharks such as horned sharks and spiny sharks change their teeth. Sharks have serrated teeth, so that they can not only bite their prey, but also effectively saw them apart
the jaws of great white sharks are not closely connected with the head
because the jaws of the great white shark are not closely connected with the head, it can extend the jaws upward and forward to swallow the prey, sometimes even swallow the prey in one bite<
most of the sharks live on carrion
sharks feed on injured marine mammals, fish and carrion, eliminating the weaker members of the animals. Sharks also eat garbage and other waste from ships. In addition, some sharks also hunt a variety of marine mammals, fish, turtles and crabs. Some sharks don't eat for months, and the great white is one of them. It is reported that great white sharks only eat once every one or two months
great white shark is a predator who is good at camouflage
great white sharks are not as flexible as other sharks because of their large size. But the great white shark is a great hunter, because it always comes as a surprise. Its upper body color is very dark, the lower body is very bright, they can use this protective color to quietly approach the prey. When it comes from below, because its color is close to the deep sea, it will not be found until it attacks. It rarely attacks from above, but when it attacks from above, its white underside blends with the bright sky reflected by the sea
in ancient times, sharks were called mackerel, shark and sand fish. They were huge creatures in the sea, so they were called "wolves in the sea". The nostrils of sharks are located in front of the ventral mouth of the head. Some of them have an oronasal groove and are connected between the corners of the nose and mouth. The folds of the olfactory sac increase the contact area with the external environment. Sharks belong to cartilaginous fishes. They don't have swim bladders on their bodies. Their ups and downs are mainly regulated by their large livers. According to fossil investigation and scientists' calculation, sharks have lived on the ground for about 180 million years. They existed as early as 300 million years ago and have not changed much in appearance so far. This shows that they have a strong survival ability and are called "hunters" of the sea
sharks do not prey in groups
How to catch the shark with hook fish
game
do you think it's not so easy to catch the shark with hook fish, hey, but there are skills, do you want to know
shark catching skills:
1. When the shark swims to the position in the picture, as shown in the figure, release the fish hook. This angle can catch the shark very well
use these two skills to catch sharks, nine out of ten, ha ha, players, hurry up and play
The urea proced by shark protein metabolism will not be eliminated from the body immediately, but will remain in the body in large quantities, so that the osmotic pressure of blood is higher than that of sea water, so that fresh water can be directly absorbed from sea water, and the excess will be eliminated from the body
sharks urinate through their skin. The meat is full of urea and the smell of ammonia. The smell of ammonia is actually a kind of urine smell. Sharks have no urinating organs. They urinate through their skin, so the meat of sharks is full of strong urine smell
sharks existed on the earth as early as 300 million years before the appearance of dinosaurs, which has been more than 500 million years, and they have hardly changed in nearly 100 million years. Shark, called shark, shark and sand fish in ancient times, is a giant in the ocean, so it is called "wolf in the sea"
the traditional idea is that the protein in shark's cartilage (shark fin) is very high, but this is wrong. Eggs have far more protein than shark fins. In addition, studies have shown that shark fins contain a certain amount of neurotoxins, which are potentially harmful to human health. Because of decades of hunting, sharks are at risk of extinction
Sharks breathe with their gills
gill is the main respiratory organ of shark. The gill is located in the pharynx, which is called branchial cleft from the pharynx to the outside. The branchial cleft of teleost is protected by Gill cap on the outside. The epidermis of the anterior and posterior walls of the source fissure forms many horizontal folds, called gill filaments, which are filled with microvessels
the breathing movement is mainly completed by opening and closing the gill cap, and the water enters from the mouth and is forced to pass through the gill cleft. Then, the process of water flowing in and out of gills from the opening of the rear end of the monitor is also called the gas exchange process
sharks belong to cartilagina, Lamellibranchia of vertebrate phylum, marine, a few species enter fresh water, and are a group of fast swimming medium and large marine fish
the internal skeleton of shark is completely composed of cartilage, often calcified, but without any true bone tissue, the exoskeleton is not very developed or degenerated, the body is often covered with skin teeth (scales), the teeth are diverse, with hard muscles, but the membranous bone never exists, and the brain is seamless
The superior frontal was composed of quadrate palatine cartilage and the inferior frontal was composed of Meister's cartilage. The latest research shows that there are many bioactive ingredients in shark, such as anticancer factor, squalene, mucopolysaccharide and so on. Shark medicine was first seen in the collection of Materia Medica. In Chinese folk, shark cartilage extract and shark liver oil have long been used to treat cancer and other diseases1. Soak the shark in warm water for 5 minutes, then pick up the shark and scrape the sand off the skin with a knife
2. Cut the shark into strips and put them into the dish
3. Then add the ingredients and seasonings into it and steam them through water.

Heterodontus Francisci, commonly known as squab, is a species of tiger shark. They can grow up to 122 cm long and have brown bodies with black spots. They are distributed from central California to the Gulf of California in Mexico, and may also be found in Ecuador and Peru. Most of them are nocturnal and lazy ring the day. If they are harassed, they may bite people.
the living environment of the tiger shark includes rocky reefs, kelp forests, marine forests, etc They feed on invertebrates, including sea urchins, crabs, abalones and other fish.
tiger sharks are oviparous, with eggs about 12-14cm long, in kelp color and spiral shape, At present, scientists have found that there are four blood types of horned sharks growing in the Gulf of Maine in the United States.
if it wasn't for horned sharks, you might have bought a fish.
