11 Diurnal Snakes To Avoid (A to Z List With Pictures)

While most snakes hunt during the night to avoid predation, there are also many that are active during the day. These snakes are called diurnal snakes and include rat snakes, garter snakes, corn snakes, and cobras among others.

Even nocturnal snakes will often come out to warm themselves on rocks during the day because snakes need the sun to balance their temperature and synthesize vitamin D.

When we refer to diurnal snakes, we’re often referring to snakes that have a clear pattern of sleeping at night and both sun warming and hunting during the day.

How do Diurnal Snakes Hunt?

Snakes have poor eyesight. Even in the light of day, it is difficult for them to see, so they rely on their powerful sense of smell and infrared sensors to detect their prey.

What this means is that regardless of the snake’s hunting time, it does not rely all too much on its vision.

Some snakes, like pit vipers, have a heat-sensing vision. They use it not only at night but also during the day. Pit vipers in the desert hunt in the daylight.

Another method that diurnal snakes use is smelling. Snakes have a powerful sense of smell. They flick their tongues to get a feel of their surroundings, and this is how they primarily hunt. 

Coupled with their ability to “hear” sound from the air and the ground, they have what it takes to succeed in hunting. 


All snakes will have diurnal activity at one point or another. There is no such thing as an exclusive nocturnal snake. 

Snakes need the sun. Those active within the day are a product of their evolutionary process in relation to their environment.
