They are immune to the poison and they secrete it through their skin as a defense mechanism against predators. This poison is so efficient, the native people of the South American Amazon rainforest use the frogs' toxins on their weapons to kill their prey, giving the frogs their nickname the "poison dart frog".
The golden poison frog (Phyllobates terribilis), also known as the golden dart frog or golden poison arrow frog, is a poison dart frog endemic from the rainforests of Colombia. The golden poison frog has become endangered due to habitat destruction within its naturally limited range. Despite its small size, this frog is considered to be the ...
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. [2] These species are diurnal and often have brightly colored bodies.
Like all Dendrobatidae, D. leucomelas frogs secrete toxins from their skin, which they gain from eating certain unspecified arthropod prey. It is uncertain precisely which arthropods lend their toxicity to which genus of Dendrobatidae, but one such arthropod is thought to have been identified as a possible source of the toxin for Dendrobatidae Phyllobates terribilis (aka the golden poison frog ...
This makes the species even more unique, as PLOS One said, because other frogs that skip the egg step typically give birth to froglets, or baby frogs, but these frogs still give birth to tadpoles.
In their natural habitat, P. bicolor excretes toxins from pores in its skin. [10] The frogs cannot naturally produce the toxin, so they derive the nutrients necessary from their diet and surrounding environment. Between 2-200 micrograms of its poison, a batrachotoxin (BTX), is enough to kill a human being (a reported LD50 of 2.7 ± 0.2 μg/kg ...
