English: Slow motion movie clips of naïve tentacled snakes striking. The gray mask provides a reference to the position of the fish when strikes were initiated. Clips 1–10 show snakes striking at a fish below a transparency sheet barrier. The fish usually responded to the snake's body feint with a C-start despite the barrier. Snakes aimed for the future location of the moving fish head. Clips 11–15 show snakes striking at a fish below a glass barrier. In this condition, the fish never executed an escape response, suggesting visual cues from the snake played little role in the escape response. Clips 16–25 show snakes striking downward at fish below the transparency sheet barrier. Clips 26–27 show some of the first strikes by a snake at fish without the barrier in place, illustrating the downward strike and capture.
