Garter snakes are diurnal, which means they search for their prey during the day time. Generally, they are resistant to the poisons of other animals such as toads and have the ability to absorb some of the toxins. When the toxin finds its way into their system, they become poisonous as well. Their level of toxicity poses no threat to humans, however, it’s helpful for them when it comes to hunting and deterring potential predators.

These reptiles have very complex systems of pheromonal communication and can find other snakes by following their scents. There is a distinguishable difference between the trail left by a female and by a male, but a male garter snake can produce both male and female pheromones to fool other males during the mating season.
