No they are not. Many zoos and local breeders care for a variety of species of Dart frogs.
Poison dart frogs emit poison from their skin. Natives who extract the poison from the frogs may roast the frogs over a fire, but the poison from many species is so potent, they can simply rub the tip of their arrows on the frog's skin without harming it.
The skin of many poison-dart frogs is red.
There are many species of poison dart frogs, but the genus names are Dendrobates, Phyllobates, Mantella, Ameerega, Oophaga, Ranitomeya and Hyloxalus. Until recently most species were withing Dendrobates, Phyllobates and Mantella, but they have undergone revisions and additions.

There are many poisonous amphibians, in which case poison dart frogs are notorious.
With an average of only 10 people die by poison dart frogs every year. They eat for example: poisonous ants and they get poison and kill humans.
Most species, and there are several, release an alkaloid toxin through their skin. They do not synthesize their own poison but store chemical toxins from some of the insects they eat like ants and termites. This is good since it means that many captive frogs do not have sufficient levels of toxin to harm their owners. It is the secretions of the skin of the poison dart frogs that is toxic. All the frogs of this family "borrow" toxins from what they eat that actually makes the toxins (mostly ants and mites) because the frogs themselves don't manufacture the poisons. These toxins, a few of which can be quite dangerous, are "worn" by the frogs for protection.
Some can have three to six at a time.
2 micrograms of poison can kill around 2,200 people. WOW!
No. Frogs are amphibians.
Many poison dart frogs secrete lipophilic alkaloid toxins through their skin. Alkaloids in the skin glands of poison frogs serve as a chemical defense against predation, and they are therefore able to be active alongside potential predators during the day.Although all wild dendrobatids are at least somewhat toxic, levels of toxicity vary considerably from one species to the next and from one population to another. These amphibians are often called "dart frogs" due to the Amerindians' indigenous use of their toxic secretions to poison the tips of blow-darts.
