Dendrobatidae
Dart-Poison Frogs
Dart-poison frogs derive their name from the fact that the more derived genera in this group are brightly colored and produce toxic skin alkaloids, which are obtained through the insects they eat. Three species (Phyllobates terribilis, Phyllobates aurotaenia, and Phyllobates bicolor) have been documented as being used to poison blow-gun darts for hunting animals, in Colombia. The most toxic species of any frog is Phyllobates terribilis, which produces batrachotoxins and homobatrachoxins at a level approximately 20-fold that of other dart-poison frogs.
Dendrobatids have short but strong hind limbs and are agile jumpers and climbers. They are characterized by the presence of divided scutes (thick pads of skin) on the dorsal surface of their digits. These frogs are diurnal and lay eggs on land. Many dendrobatid species exhibit parental care, with the males or females (depending on the species) transporting their tadpoles on the back of the parent. In some species, each tadpole is placed in a separate treehole or other small water-containing enclosure, and females or both parents visit the tadpoles periodically, with the female depositing unfertilized eggs at each visit to feed the tadpole. Males are highly territorial, partaking in vocalization and wrestling competitions and display cephalic amplexus
