behavioral left-right asymmetry extends to arthropods

Abstract

we present behavioral lateralizations of spiders and ants and their probable survival value. they clearly conform to the vertebrate lateralizations reviewed by vallortigara & rogers (v&r) and to earlier arthropod studies. we suggest two complementary reviews: (1) differences in lesion susceptibility and muscle strength between left and right body side, and (2) perceptual biases and predator inspection in invertebrates.
