nonpoisonous
Snakes that typically have oval-shaped heads and round eyes include many species of non-venomous constrictors, such as the corn snake and the boa constrictor. These features are characteristic of many colubrid snakes, which often exhibit a more rounded head shape compared to venomous snakes that tend to have more triangular heads. Additionally, the round eyes are a common trait among several snake species, contributing to their overall appearance.
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.
Round
The Scottish Fold cats have very large, round eyes.
It's snake.
Nonpoisonous
The coral snake as well as a number of other elapids, such as the mamba, have an oval-shaped head and round pupils.
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.
Non poisnous snakes
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.
There is a severe lack of intellectual soundness in this question.
