look for information on how to find out whether a snake is harmful
Answers
It's impossible to tell for sure if a snake is venomous, or as some people say, poisonous, just by looking at certain features. There are three major myths people seem to believe in:-
1) MYTH: It had a triangular head!
FACT: Pretty much all snakes, like 99%, have triangular heads. It's true that the venomous pit vipers have VERY broad heads, but then again, these are very fat snakes in general.
2) MYTH: It had a pattern!
FACT: A lot of snakes have patterns. And some venomous ones don't have any pattern. It seems that just because of diamondback snakes or coral snakes, people think that snakes with patterns are dangerous. But most common harmless snakes, like Garter Snakes, Corn Snakes, Milk Snakes, etc. have distinct patterns.
3) MYTH: It rattled its tail!
FACT: This is a common behavior for most snakes. Rattlesnakes just so happen to have rattles that amplify the sound. But when the tail of a safe snake rattles against dry leaves, it sounds just like a rattlesnake!
TOP 3 MOST COMMON TRAITS OF VENOMOUS SNAKES:
1) It is big and fat (all in the USA, except that red-black-yellow coral, are fat pit vipers)
2) It is a rattlesnake, with real rattles on the end of its tail
3) It has elliptical pupils (but I doubt you're close enough to look)
Answer:
Poisonous snakes have slit or vertical eyes .
