![]() The green and black poison frog was introduced in Hawaii by humans.They are solitary creatures and only prefer companionship for mating.Poison dart frogs are not good swimmers, and are mostly ground dwellers.They are active most of the day and sleep during the night. Unlike other amphibians, this species is diurnal or nocturnal. ![]() The Leimadophis epinephelus, a snake, is the only predator that has acquired resistance to the poison.The toxin is only harmful if it enters the bloodstream through open wounds, or if ingested. These frogs are sometimes kept as pets.However, they are harmless if left alone. These frogs are so poisonous that one millionth of an ounce can kill a small animal, and an amount smaller than a grain of rice is enough to kill a human being.It is believed that the venom of one golden poison frog can kill 10 humans. The golden poison frog is the one to look out for, as they are one of the most poisonous species in the world.The poison dart is so named, as some Amerindian tribes used their toxin to poison their blow darts for hunting.Scientists use it in a painkiller, like epibatidine which is 200 times more powerful then morphine. The poison also has some medicinal use.Snakes and big spiders are usually the ones who feed on them, although they can turn out to be one deadly meal! Due to their toxicity, these frogs have very few predators.Scientists believe this, as the frogs that are raised in captivity do not show signs of toxins, since they do not feed on insects that have eaten poisonous plants. The insects, in turn, acquire them from toxic plants. It is believed that the poison comes from some of the insects the frogs feed on.These deadly poisons make up for their small size. They secrete lipophilic alkaloid toxins through their skin glands when they sense danger. These frogs use their toxins as a defense mechanism.The female occasionally feeds them on unfertilized eggs till they go through metamorphosis and turn into adults. When the eggs hatch, the male frog carries the tiny tadpoles on his back (they stick to the mucus on his back) and shifts them into pools of water collected in the leaves of certain plants. They are the only species in their family that take care of their young. The poison frogs are surprisingly devoted parents.After about twelve days, these eggs turn into tiny little tadpoles. The male fertilizes the eggs and makes sure they are moist. Once the female chooses her partner, she lays a clutch of eggs in the forest canopy.They go through rather elaborate rituals of vocalization and fights for territories, to attract their female counterparts. The poison dart frog usually mates in the rainy season from mid-July to mid-September.However, in captivity, they are known to survive for 10 to 15 years too. The average lifespan of the poison arrow is 3 to 5 years in the wild.The bright colors of their skin attract insects towards them, and once the insect gets in contact with the deadly toxins from the skin glands, they experience instant death. These frogs have a rather clever way of catching their prey.They have long, sticky tongues that zap out to catch their prey, which consists of fruit insects, termites ants, and small spiders. The poison arrow frogs are meat eaters.Temperatures ranging from 72° F (22° C) to 80° F (27° C) are ideal for them. The poison dart enjoys the sun and extremely humid environments.They are mainly terrestrial, but they can climb trees easily. These frogs live in wet, moist places like streams, marshes, underneath rocks and leaves on the forest floor.Poison dart frogs love warm humid climatic conditions, and are mostly found in the tropical rainforests of countries like Costa Rica, Brazil, Venezuela, Columbia, and Ecuador, in the central and south of America.
