Monotypic prosimian genus to which the angwantibo (A. calabarensis, the golden potto) belongs; found in west central Africa; body mass around 300 g; nocturnal; arboreal; mostly insectivorous; slow methodical climbers; noyau. The second digit is reduced and the pollex is 180 from digit 3, providing for a powerful vice-like grip; circulatory adaptations in the limbs provide an ample oxygen supply that prevents lactic acid buildup.
