Laterality and cooperation: mosquitofish move closer to a predator when the companion is on their left side
Article Abstract:
Research shows that many vertebrate species exhibit hemispheric specialization of function. A new study uses mirror images to test the theory that pairs of fish play a conditional strategy when inspecting predators. Using mosquitofish, the study shows that predator inspection is less likely when the mirror image is on the right rather than the left side of the fish. Using a videorecorded sequence mixing pictures of predators with their mirror images had the same result. It is suggested that the images seen on the left and right sides of a fish may generate different types of social behaviour.

Laterality in detour behaviour: interspecific variation in poeciliid fish
Article Abstract:
Research undertaken among males of five species of poeciliid fish indicates that functional asymmetries of behaviour could be common among vertebrates. The direction of these asymmetries is generally extremely similar in closely related species. This supports the view of an early evolution of laterality in brain and behaviour. Where there are differences in the direction of laterality between species within the family Poeciliidae, they reflect contextual variables rather than fundamental differences in the pattern of laterality.

Laterality in the wild: Preferential hemifield use during predatory and sexual behaviour in the black-winged stilt
Article Abstract:
Preferential use of the left and right monocular visual field in black-winged stilts, Himantopus himantopus, during predatory pecking and during courtship and mating behaviour in a naturalistic setting is recorded. The stilts had a population-level preference for using their right monocular visual field before predatory pecking.
