Consciousness, as a biological phenomenon, may consists of states of feeling, sensation or awareness. Specialized behaviour, sophisticated actions of communication, metacognition, social interaction, spatial orientation, the use of mental maps for navigation, and spatial memory, all point to conscious processing in genus other than Homo. This work aims to identify self-awareness states in two different species: using mirror self-recognition tests in Callithrix jacchus, and using self-perception tests in Dinoponera quadriceps. Displays of C. jacchus self-recognition using a mirror, were appraised with two protocols: no mark and with mark. D.quadriceps navigational capability displays during foraging trips to food resource, were appraised considering three different tests categories: (1) free access, (2) blocked by opaque object; and 3) blocked by clear object. Our results show self-perception in both studied species. With marmosets displaying contingency check behaviour to the specular image, self-observation, environmental exploration using the mirror as a tool and little, but significant mark reactions. Tocandiras were able to perceive its own location and to calculate short return paths to the colony after obtaining the food resource in all three types of tests. Here we provide further evidence of conscious states for species other than vertebrates.
