Whatis a Poison Dart Frog?    What is Doyle's Dendrobates Den

First of all, I'm not a frog expert.  (To read more about me, Click Here) There are numerous good web pages available with informationabout dart frogs; so make sure to check my LinkPage.  My purpose here is to present information that I haveencountered, but have not seen covered on other web pages.

First, what is a "Poison DartFrog"? This term is used to describe the colorful frogs of  thefamily Dendrobatidae.  These frogs, like many other amphibians, secretetoxins from their skin.  The frog that gave this group of frogs itsname is the Golden Poison Dart frog (Phyllobates terribilis). TheChoco' Indians of Pacific river areas of Colombia use the secretion fromthe back of Phyllobates terribilis to coat their darts with poison. This is done by rubbing the tip of the dart along the back of the frog. When the frog is agitated it will secrete a poison from the pores on itsback.  This toxin is non-protein-based (alkaloids) and one frog mayhave enough toxin to provide a lethal dose to 10 adult humans.  Thismakes Phyllobates terribilis the most toxic animal in the worldthat has a non-protein based toxin.




Now, why would any one want to keep an animalthat could potentially kill them?  First, most of the frogs of this group are not poisonous enough to be a threat to humans. Only 3 species could cause a serious threat, and they are:  Phyllobatesterribilis, Phyllobates bicolor, and Phyllobates aurotaenia. Most of the frogs would only cause a serious health risk if ingested. When the frogs are kept in captivity, they lose their toxicity. The reason for this is not completely understood, but it is believed thatthe frogs obtain the alkaloids from the insects they eat and the insectsobtain them from the plants they eat.  Being that the frogs do nothave a source alkaloids in captivity, they cannot generate the toxins.

But still, why do people keep these frogs? These are some of the most colorful and interesting animals in the world. Not only are they colorful, such as green and black, blue and black, andyellow and black just to name a few, but each species has its own personalities.
