In slightly mis-aimed celebration of Pot Week (which comes into existence with this mention of it), here’s a potto study: “L’Allure du Potto (Perodicticus potto Mûller, 1766)(Lorisinae, Primates) au Cours de son Déplacement sur un Support Horizontal,” S. Renous and J.-P. Gasc, Annales Des Sciences Naturelles, vol. 13, 1980, pp. 117–130.
