Movie 1.

Reconstruction of 3D kinematics of the feeding strike of viper from two views. Sequence 1: full speed strike by Deinagkistrodon acutus (ID STV1747-0001) (1000 frames per second), completed in 0.11 seconds. Sequence 2: snake strike at 3% speed (30 frames per second). Sequence 3: two simultaneous views of snake strike from 90^° (top, video 2A) and 60^° (bottom, video 2B) with landmarks on snake and gel prey placed on both views. Sequence 4: landmark movement in 3D space reconstructed from two views. Line colours match landmark colours in Sequence 3, and jaw landmarks connected with pink lines to show jaw opening and closing.
