FISHES CARE FOR THEIR PARTNERS
When it comes to helping each other, some fish are better than previously thought. New research by Australian scientists has found that couples of rabbitfish cooperate and support each other while feeding.
While documented this behavior in birds and very social mammals, previously it thought was impossible to fish.
In pairs of coral reef rabbitfishes (family Siganidae), one fish frequently assumes an upright vigilance position in the water column, while the partner forages in small crevices in the reef substratum. Both behaviours are strongly coordinated and partners regularly alternate their positions, resulting in a balanced distribution of foraging activity.
Reciprocity is frequently assumed to require complex cognitive abilities. Therefore, it has been argued that reciprocity may be restricted to animals that can meet these demands
Photo: The foraging individual (in the head-down position) feeds in cracks and crevices in the substratum, while the vigilant individual is positioned in the water column with its head up. Note the obstructions to the visual field of the forager, suggesting high vulnerability to predation and the unobstructed field of perception of the vigilant fish.
