All snakes are hunters and predator feeding on the animals and sometimes their exps Hevingne limbs, snakes cannot hold their preys down to bite, héose, they usually swallow them whole. Poisonous snakes sometimes do immobilize their prays with their venom to make consumption easier. Most poisonous snakes are conspicuously coloured to warm others off One example is the redheaded krait that has a bluish black body and scarlet head and tail. Snakes like the cobras, which have less outstanding body colours, display their fatality by lifting the front part of their body and spreading their hoods.. It is truly a myth that poisonous snakes attack humans for food! Humans can never be their targets for food as we are normally too large for them to swallow In cases where snakes do bite, these attacks are usually defensive ones and the venom injected is normally little or sometimes even none. The full, fatal dose of the venom is only released on smaller animals, which the snakes can swallow easily. Besides helping in the killing and immobilizing of their preys, the polson also acts is digestive agents for snakes. Why then is the vepom so deadly? In general, there are three kinds of poisons in the venom, though in varying amounts, depending on the type of snake in question "Venoms usually contain substances that weaken the blood corpuscles and the lining of the blood vessels Profuse bleeding. often a common result of snakebites, is caused by the anticoagulants present in the poison which prevents blood clotting. The paralysis of the heart and respiratory muscles is performed by the nervous system attacking toxins. Though these bites are deadly, certain actions can be taken to slow down the spread of the venom, hence saving the victim's life. Attempting to incise and suck at the spot of the bite is more likely to be harmful than a cure. "The poisonous venom usually travels tast into the body upon being released; hence sucking at the mouth of the wound will not help remove the poison, rather, incising the bite may lead the victim to great pain and further profuse bleeding Instead, a broad. firm crepe bandage should be applied over the wound to compress the tissues and prevent the spread of the venom. After which, the victim must be duly sent to the hospital for professional treatment.
