Simply because not all snakes have the mechanism to produce venom. Constrictors developed an alternative method of subduing their prey, since they lack venom and fangs.
well snakes are creations by god and are slithering creatures, there are 3 groups of snakes, venomous, nonvenomous, and constrictors. venomous snakes are snakes that are deadly so you do not want to get near them, how you can tell the snake is venomous you can look at it head shape, if its a triangle its a venomous or a constrictor. it will have a round head if its a nonvenomous. constrictors are snakes that will squeeze and choke you then eat you. lucky for us they are mostly inAfrica. if you were to FUD a snake its most likely to be nonvenomous. P.S. if you live in the south west in America and you hear a rattle? RUN!!!!!!!!!!!!!!!!! P.S.S. cause that's a rattlesnake (very deadly). BE,VERY CAREFUL !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Some snakes kill by constricting the prey until dead - boas, pythons, gopher snakes, etc. Some, such as garter snakes simply overpower the prey with their jaws and swallow the prey. See the image above.
Birds of Prey, other snakes.
Some birds of prey, such as hawks or owls, will eat snakes.
Snakes use the vitamins and minerals that they get from vegetarian prey. A mouse is omnivorous as are rats, these are the most eaten prey animals for snakes along with birds, other snakes, lizards, frogs, fish and some will eat worms or insects. Some snakes have evolved to be a species-specific prey-eaters, like the snakes that eat eggs.
Boas are constrictors. Meaning they're not poisonous, but squeeze and choke their prey to death. Unless they'd settle around the throat, they're not dangerous to humans.
Rattle snakes are their prey.
seman...
Snakes do not chew their prey, they swallow them whole. Snakes have curved teeth along the whole length of the mouth to hold prey and keep it from escaping. Some snakes have hollow or grooved teeth for injecting venom.
Some snakes use camouflage to hide themselves from prey using the plants around them. Some of snake's prey eat plants, so if plants disapeared, then so would snake's prey.
they can if they tried
in the UK it is illegal to feed snakes live prey but people do !! if you have a larger snake and do feed it live prey some will constrict until the prey is dead but other will eat it alive and it will still be chirping or making a noise as it passes down the snakes body until it suffocates !you can view snakes eating live prey (rabbits ,birds ,chickens) on youtube
