Depends on what you mean. If you mean are snakes camouflaged - the huge majority are - they are almost exclusively ambush predators so camouflage is almost essential.
Yes Coral snakes can sense danger. Many others too. Not all snakes can sense danger. A water snake example, can not sense danger if an animal or human is looking to kill it or hunt it down. Tree snakes also, can not sense danger of near predators ; even pray, which is not danger to the snake, it is food. Snakes have amazing ways! Snakes are beloved animals even some,that are not poisonous, can be pets. Snakes are amazing!
The correct spelling is 'camouflage'.

There is no answer for this question because it does not make any sense.
Like most snakes - their underside consists of long, rectangular scales. They are usually white or cream-coloured (the underside doesn't need camouflaging) The scales overlap in the direction of their tail - enabling them to gain purchase on the ground as they move forwards.
All snakes can't hear but they have a good sense with their tongue.
