Ranitomeya imitator (formerly Dendrobates imitator), is a species of poison dart frog found in the north-central region of eastern Peru. Its common names include mimic poison frog and poison arrow frog , [ 2 ] [ 3 ] and it is one of the best known dart frogs. [ 4 ]
Ranitomeya and Andinobates frogs can be distinguished from those in genera such as Dendrobates in that they are generally smaller, have more than two colors, and seem to glitter if viewed from certain angles. Ranitomeya is widespread in the Amazon basin, whereas Andinobates species are found only in the northern Andes down to Central America.
The mimic poison frog Ranitomeya (Dendrobates) imitator is polymorphic, with a striped morph that imitates the black and yellow striped morph of Ranitomeya variabilis, a spotted morph that imitates the largely blue-green highland spotted morph also of R. variabilis, and a banded morph that imitates the red and black banded Ranitomeya summersi.
The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), [1] [3] is a brightly-colored member of the order Anura native to southern Central America and Colombia. This species has also been introduced to Oahu, Hawaii in an effort to lower mosquito numbers.
While Ranitomeya imitator can copy the appearance of R. summersi, R. summersi can be distinguished from the imitator by its soft buzz call which can only be heard less than 1 m away, and its dark mask which covers the tympanum. In contrast the Ranitomeya imitator calls are much louder and can be heard from 5 m away. [2]

Many species of tropical frogs have an inherent nature of cannibalism, such as Dendrobates vanzolinii, that allow their tadpoles to utilize the eggs for nourishment. [4] With a male guarding the eggs, an intermediate step to developing biparental care may have been using the eggs from a mating with another female to feed existing tadpoles. [1]
Dendrobates variabilis Zimmermann and Zimmermann, 1988 Ranitomeya variabilis , formerly known as Dendrodates variabilis , is a species of small poison dart frog distributed in northern Peru , along the eastern slope of Andes in the upper Rio Huallaga drainage basin .
