Behavioural Brain Research
Limb preference is a behavioral indicator of lateralized brain function that was recently elucidated experimentally in lower vertebrates. We assessed natural spontaneous limb use of nesting eastern Pacific leatherback turtles by recording which hindlimb flipper was extended overtop the cloaca to cover the egg chamber during oviposition. We found a population level right bias in 1889 observations of 361 individuals. This is the first report of a limb preference in Testudinata.
