Pre location by clownfish (Amphiprion perideraion) larvae feeding on rotifers (Brachionus plicatilis)

Prey location by clownfish (Amphiprion perideraion) larvae feedingon rotifers was accurately characterized. Cruise predator cloworishlarvae locate prey throughout a threedimensional search space,not only on the boundaries of this space as previously predicted.The search space ranged from 0 to 120° away from the lengthaxis of the fish in the horizontal plane and from 0 to 150°in the transverse plane. The boundaries of the search spacewere 1.3 body lengths away along the axis of the fish and 1body length away to the sides and above. First-feeding clownfishlarvae have well-developed visual acuity and binocular vision.
