Grass snake vs toad
This grass snake crossed my path while walking in the Black Forest, Germany. I was alerted to it by the distressed baby cries from a large toad/frog with its thigh caught between the snake's jaws. They seemed evenly matched in this struggle for survival and I was unsure whether to intervene. However soon after taking the photo they both disappeared into the undergrowth, still wrestling and were never seen again, at least not by me.
