Poison dart frogs secrete an alkaline-based poison from their skin. The toxicity that makes up this poison is obtained from their diet. As poison dart frogs do not eat these insects in captivity, they do not obtain these necessary toxic compounds and therefore lose their toxicity.
During the breeding season, males will call loudly to attract a female. Should more than one female approach a male; it is the females that will ght to win the opportunity to mate. The winning female will stroke the male on his snout and back in a courtship display.
Poison dart frogs lay a small clutch of between 2 and 6 eggs. The male will keep them moist until the tadpoles hatch out. Once they have hatched, the tadpoles are carried to small pools of water within water collecting plants on the backs of both the male and the female. After this, the female will return to the tadpoles every few days and deposit an unfertilised egg for the tadpole to eat. The tadpoles take 2-3 months to develop into adults.
