Chemical cues from a predatory fish (Parapercis colias) suppress feeding rates of the New Zealand sea urchin (Evechinus chloroticus).

There was a weak trend of reduced change in daily position (relative to body size) in small urchins exposed to blue cod, but little to no statistical evidence for any association with predator treatment in either size class (Small: − 3.13 body lengths, p = 0.13; Large: + 1.06 body lengths, p = 0.88; Supplementary Table S3 ).
