You got 75%, Oren Coral snakes don't have triangular heads and their
pupils are round...kissing cousins to cobras, toxin of both is neurotoxic
rather than hemotoxic as in the three vipers you mentioned.

You got me G Coral snakes don't strike. They have to chew through
the skin, likely in tender places like between your fingers or thumb.

Ordinarily, a person would notice that before the venom is finally
delivered. And notice the rings on a coral snake.
