It varies from snake to snake.
Most will run if threatened.
Some have venom as defense, some play dead, some bite, others pretend to be venomous snakes like cobras or rattlesnakes; some snakes will even whip their tail at predators in defense.
They protect themselves by burying themselves under sand and of course their poisones bites.
By biting people
they bite! but first they usually hide or run away
Every predator apart from snake, crocodile, and fish
by making itself look like a venomous sea snake
They stand tall and then hiss a lot means back a way fast.
They use camoflauge and they are also constrictors. They will constrict themselves around the prey or predator to stop them from breathing which will get the predator to let them go or they will eat it and swallow it whole.
every animal has a way to protect themselves for example, a snake would stay in the shade at day and come back out at night or, a zebra a zebra's stripes reflect the sun's rays so they bounce off.
They protect themselves by squirting ink.
It either coils up and raises its head or it will turn and slither away, if it has the option of doing so. It also depends on what breed of snake is being threatened. Venomous snakes of course will defend themselves and strike. However, docile snakes tend to coil up and protect themselves.
yes snakes are very protect of there surroundings .
Citizens protect themselves with police departments. Nations protect themselves with a military.
