A young Taiwanese pangolin embarks upon his search for a mate before the breeding season ends. Pangolins are the world's most trafficked animal, so it is crucial he finds a female in time. After facing a large cobra and feasting on tree-dwelling ants, he reaches the very edge of his known territory. In a small fragment of the Atlantic Forest in Brazil is a family of golden-headed lion tamarins. These tiny, endangered primates are unique to this area. With only 12% of their habitat remaining, mum, dad and their three boys need to move away from their old home in search of more food.
