Fig. 6: Example school behaviour after stimulation.
From: Social familiarity improves fast-start escape performance in schooling fish
Each arrow shows the position and orientation of one fish. Successive frames from top to bottom illustrate the school’s cohesion and alignment at 0 ms (the moment immediately before stimulation), +20 ms (during the escape response), and +100 ms (following the escape response) post-stimulation. The experimental arena measured 50 cm (long) × 40 cm (wide), with directional flow from right to left in the illustration. Both illustrated schools were stimulated by the right lateral stimulus, with an identical lateral stimulus on the left side of the arena, relative to the directional flow (both 2 cm from each of the lateral walls in the centre of the swim tunnel). To control for a stimulus side preference, the use of the left or right lateral stimulus was alternated between trials.
