TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Order: Anura
Family: Dendrobatidae
Genus/species: Oophaga (formerly Dendrobates) pumilio
GENERAL CHARACTERISTICS: Despite the common name, coloration is reportedly highly variable among locations with up to 30 color morphs . Individuals may be ripe-strawberry red, brilliant blue, deep green or brown. The limbs are marbled dark blue and black. Body is slim, snout is rounded, the eyes large. The long, slender forelimbs end in finger and toe tips expanded into adhesive discs. Length to 2.5 cm (1 inch).
DISTRIBUTION/HABITAT: Nicaragua, Costa Rica, Panama. Primarily terrestrial in tropical rain forest leaf litter and decaying vegetation.
DIET IN THE WILD: Hunts diurnally, primarily upon ants and oribatid mites.
PREDATION: Night ground snakes are immune to the toxins of O. pumilio. Tadpoles are often consumed because their poison glands are underdeveloped. They are in danger of an aggressive fungus – Chytrid Fungus – that is killing off frog populations around the globe.
REPRODUCTION: The male protects and keeps their eggs moist until they hatch. Then the female carries the tadpoles to a water filled bromeliad where the young feed on unfertilized eggs (oophagy).
CONSERVATION: IUCN Red List: Least Concern (LC)
population numbers are currently high despite illegal capture for the pet trade and habitat loss.
REMARKS: Alkaloids in the skin glands of poison frogs serve as a chemical defense against predation, and most come from the oribatid mites. In captivity, with a non-native food source, they lose their toxicity.
