The Cobra does not hear, as it is believed, the snake -charmer's flute. They can, however, feel vibrations through the ground or whatever they are resting on. Depending on the species, snakes may be egg-layers or give birth to live young. They generally mate in the spring, shortly after leaving whatever hollow, burrow or rock crevice has sheltered them through winter hibernation. Egg-layers usually deposit groups of eggs in dirt, beneath stones or logs, or in piles of decaying wood or vegetation during late spring or early summer.
Most snakes hatch or are born in late summer.
Whether deposited as eggs or dropped as fully formed miniature adults, snakes are on their own from the start. Snakes do not take any responsibility for the care and protection of their young. Most snakes mature at one or two years of age, and individuals may live up to twenty years in the wild. The greatest age known for any snake is just under 30 years, attained by both the anaconda and the black-lipped cobra. Effects of the bites of Black and Green Mamba - Black and green mambas both produce neurotoxins, which is why they kill so fast.
