Dendrobatinae

Dendrobatinae is the main subfamily of frogs in the family Dendrobatidae, the poison dart frogs of Central and South America, found from Nicaragua to the Amazon Basin in Brazil.
Description.
Dendrobatinae are generally small frogs; "Andinobates minutus" is as small as in snout–vent length length. Many species are brightly colored and all are toxic. Alkaloids in "Phyllobates" are particularly potent.
All species are presumed to show parental care, often by the male. However, some species show biparental care ("Ranitomeya"), whereas in "Oophaga" only females care for the tadpoles, feeding them with eggs, their only source of nutrition. The males are responsible for protecting the eggs from predation and keeping the eggs from drying out by urinating on them.
General.
There are eight or seven genera in this subfamily: 
The most specious genera are "Ranitomeya" (16 species) and "Andinobates" (13 species). "Dendrobates" used to be much larger but currently contains only five species, having had most of its species split off into genera erected later.
