English: Slow motion movie clips of both experienced adult and naïve tentacled snakes striking. The gray mask provides a reference to the position of the fish when strikes were initiated. Clips 1–7 show adult snakes twisting their head around and under their body when striking at fish. Clips 8 and 9 show the same strategy employed by a naïve tentacled snake striking at a fish below and glass barrier (8), and striking at the first fish introduced without a barrier in place (9). Clips 10–13 show adult snakes startling fish closer to their jaws during the strike in a manner that may extend their range. Clips 14–15 show naïve juvenile snakes employing a similar strategy striking at fish below a plastic barrier. Clips 16–18 show juvenile snakes striking and wild-caught Gambusia with a polyvinyl barrier in place. Clips 19 and 20 show a large adult tentacled snake striking with no barrier in place and exhibiting a more distinctive body feint to startle the fish.
