There are no poisonous snakes but there are venomous snakes. One needs to be familiar with the species of each area as there are no general rules concerning shapes of the head or eyes. Vipers usually have a triangular shaped head. However, in many areas of the world there are species of snakes without a triangular head that are highly venomous. When planning a trip into unfamiliar countries it is best to purchase a guide book to the local species.
No snakes are poisonous, they are venomous. The only way you can tell is by researching snake species in your area and finding photographs of the type of snake you saw. Once you are familiar with the animals in your area you will be able to tell. Venomous snakes come in all shapes, colors, and sizes so there is no way to tell unless you know the species. You can easily Google "Snakes in (your area)" and get good results.
The myth that a venomous snake will have a triangular/diamond shaped head is false. There are many venomous snakes with oval heads (such as the Coral Snake and Black Mamba), and there are non-venomous snakes with triangular/diamond shaped heads, (such as many Boa and Python species).
Look at the bottom of the snake, notice the pattern of the lines. Once you get down to the anus, if the lines change pattern, it is not poisonous. But if it stays the same, it IS. Also, if you look at its eyes, if the eyes are slitted like a cat's, it IS poisonous. If they are round like a person, it is not.
EDIT: Sorry Lindsey - There is NO way to tell if a snake is venomous or not just by looking at its physical design ! Many non-venomous species share traits with venomous ones (and vice-versa) - the only sure-fire way is researching which snakes occur naturally in your locality. At least that way you'll have an idea what to look for if you encounter a snake in the wild... Snakester1962 (Supervisor)
PS: no such thing as a poisonous snake, they are venomous! Poison is something you can digest and it would harm you. Venomous, refers to something being injected into your bloodstream.
First off they are venomous not poisonous.
The way to tell if one is venomous is a venomous snake has a triangular shaped head.
Second another way that involves less danger is to look in a book on reptiles in your area (they have pictures of the snake usually)
A poisonious snake has a triangular shaped head, whereas a non poisonous snake has a more rounded head.
you wait for it to bite you and see if you start feeling like you've been poisoned that'll probably be a dead giveaway :) hope this helped :D
Only one thing is sure. If the snake has a triangular-shaped head, it is a viper of some king and venomous. However, if it does not have a triangular head, it may still be dangerous as there are many very dangerous snakes that have a more rounded head. Be familiar with the snakes in your specific area of the world.
The only way to distinguish between venomous and nonvenomous snakes is to obtain a guide to the snakes of a particular region. There is a myth that a snake with an oval head and round pupils is nonvenomous. If that were true, the snake pictured above of the deadly green mamba is harmless.
Nonvenomous snakes have round pupils; venomous snakes have elongated pupils that look like slits.
By making yourself aware of the local species of venomous snakes. You cannot tell for certain just by looking at a snake whether it's venomous or not !
Snake
the diffrence is that you tell them to make it
I am not sure about the tail scales-but if the head of the snake is triangular it means that that particular snake hold venom in his cheeks.
I do not know , please tell me as well.
yeah if it starts running
The shape of a poisonous snake's head will be TRIANGULAR. Stay AWAY from those. They are NOT good news. :) Best of wishes! Xx
no in fact a northern pine snake would rather run away from you then try to bite you it is not poisonous and if u dont no how to tell a poisonous snake from a non poisonous just look at the eyes if the eyes have a round pupil it is non poisonous but if its got a cats pupil it is most deffenetly poisionous and i would sugest to get as far away from t as possible
If you look at the bottom of its tail, notice the pattern of the lines. Once you get down to the anus, if the line pattern changes, it is NOT poisonous. But if it stays the same, it IS poisonous.
If the caterpillar is harry that usually means it is poisonous, and or, EXTREMELY dangerous. So... WATCH OUT!
sounds like a rattle snake. Does the head come to a point and you can tell the difference between the body and head? If so it is a rattlesnake.
Hard to tell for sure without seeing a picture, but it could be either a Black Ratsnake or a Coachwhip, neither of which is poisonous. But do not assume any snake is non-poisonous without a positive identification.
The shape of it's head If the snake has a diamond shaped head, it is poisonous, and if the head is round, it is not poisonous
