Cover: Koalas possess a unique morphology for extant marsupials linked with their arboreal lifestyle in the eucalypt forests of eastern Australia, with elongated limbs, an opposable hallux and zygodactyllous hands (two opposable digits per hand), reminiscent of other canopy specialists such as primates. Gaschk et al. (jeb207506) explored whether this morphological convergence is also present in their gait characteristics. Koala strategies converged on primate locomotion in arboreal environments, but were marsupial-like for terrestrial locomotion, suggesting that the gait properties of primates and koalas convey an advantage during arboreal locomotion, likely linked to stability on narrow or unstable substrates.
