The Granular Poison Frog is a diurnal (active during the day) species of frog. The males of the species are highly territorial in regards to their calling and breeding sites, even attacking other males. After breeding, the males will brood the eggs and keep them moist. After the eggs hatch, the females transport the tadpoles on their back to a water-filled plant. The females will lay unfertilized eggs for the tadpoles to feed on. The Granular Poison Frog is listed as Vulnerable by the IUCN due to habitat destruction and habitat fragmentation. Logging, agriculture, and expanding urbanization are causing this.
