Artificial intelligent assistant

Recognition of snake (image) I would like some help with the recognition of the snake shown in the image below. I was doing a fieldwork in a forest in Slovakia when I found it. I was thinking it could be a water snake but I am no expert in snakes. Does someone know what kind of snake is this? ![image of snake](

Aesculapian snake ( _Zamenis longissimus_ ). Common european species, non venomous, rodent/egg eater.

edit1: they can swim and can be found next to water bodies but are terrestrial.
