Non poisnous snakes
You need to be more specific - that vague description could apply to any one of a thousand species !
Snake eyes
snake eyes
The odds of rolling snake eyes (two ones) on a pair of dice is 1 in 36, since there are 36 possible outcomes when rolling two dice. To find the odds of rolling snake eyes twice in a row, you multiply the probabilities: ( \frac{1}{36} \times \frac{1}{36} = \frac{1}{1296} ). Therefore, the odds of rolling snake eyes twice in a row are 1 in 1296.
1/36
The coral snake as well as a number of other elapids, such as the mamba, have an oval-shaped head and round pupils.
There are species of both venomous and nonvenomous snakes with oval eyes. The snake pictured above is a mamba - a deadly species.
Nonpoisonous
As a general rule of thumb, non-poisionous snakes usually have oval shaped heads and round eyes. Venomous snakes tend to have more angular heads and eyes.Nearly impossible to answer here, many snakes have "oval" shaped heads and most of the harmless snakes have round pupils. One venomous snake that would fit this category is the Coral snake.
Nonpoisonous, THIS ANSWER IS NOT TRUE, THE CORAL SNAKE HAS WHAT COULD BE CALLLED AND OVAL SHAPED HEAD AND HAS ROUND PUPILS.
There are both venomous and nonvenomous snakes that meet that description. The image above has round pupils and an oval head. It is the deadly mamba from Africa.
Round
nonpoisonous
You can research the species by its color and its length. If the snake has 'cat eyes' instead of round pupils, it is poisonous. That is not to say that round means it is not poisonous, as there are a few.
Start by drawing the head of the snake, which is typically shaped like an oval. Then, add a long, curvy line to represent the body. Finally, draw a tail at the end of the body and add some details like scales or eyes to complete the drawing.
It is possible, but extremely rare. If a snake has two heads, that means four eyes instead of two. I don't know if a snake can have more than two eyes on one head, but yes, having more than two eyes is possible for a snake.
The word "snake". Snake oil, rattlesnake and snake eyes.
