Ethogram' of zebrafish related to vision

Behavior	Description	Tectum involved?	Selected references
Visual startle	Sudden fast start following sudden changes in ambient light levels	Unknown	[62-64]
Photomotor response	Muscle contractions in response to very bright light	No	[65]
Visual background adaptation	Neuro-endocrine response of melanophore pigment cells to ambient light levels; melanin granules aggregate in bright light	No; probably AF1	[66,67]
Circadian photoentrainment	Responses in physiology and behavior to the natural light-dark cycle	No; probably AF1	[68,69]
Phototaxis	Swimming and turning toward a light source	Yes	[70-72]
Scototaxis	Preference for a dark compartment	Unknown	[73]
Dorsal light response	Tilting of the body axis toward a light source	No	[74]
Optokinetic response	Slow eye movements following the motion of a large stimulus; punctuated by saccades	No; possibly AF9	[62,67,70,75,76]; F Kubo and HB, unpublished work
Optomotor response	Turning and swimming in the direction of a large moving stimulus	No	[67,77-79]

Visual obstacle avoidance	Fast start to prevent collision with approaching object	Yes	[80]
Visual escape response	Escape turn away from any large moving object	Yes	[81]
Prey capture	Complex behavior involving J turns, slow tracking swims and fast capture swims in pursuit of small prey	Yes	[16,82-84]
Predator avoidance	Complex escape behavior; probably requires predator recognition	Yes	[85,86]
Shoaling	Grouping with conspecifics; shown by juvenile and adult fish	Unknown	[87-91]
Visual mate choice	Preference of particular shapes as reproductive stimuli by adult fish	Unknown	[92]
