Cainarachi poison frog description
The Cainarachi poison frog is a member of a group of small, New World frogs that are famed for their ability to secret powerful toxins from their skin. These remarkable frogs also have extravagant warning colourations and unique thick skin pads on the upperside of the digits (3) (4) (5). The fabulously vibrant Cainarachi poison frog is dark-red on the upperside, becoming black and bright blue and green on the limbs, with conspicuous yellow stripes extending down the side of the body. In common with other frogs in the Ameerega genus, the skin on the upperside is somewhat grainy and the first finger is noticeably elongated (6). The limbs are short, yet strong, and the Cainarachi poison frog is an agile climber and jumper (5).

The IUCN/SSC Amphibian Specialist Group:
- The fusion of gametes (male and female reproductive cells) to produce an embryo, which grows into a new individual.
- A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
- An abrupt physical change from the larval to the adult form.

Cainarachi poison frog biology
Renowned for the alkaloid-based toxic secretions from the skin, which are used to paralyse or kill potential predators, the vibrant colouration of the Cainarachi poison frog serves as a warning that it is poisonous. This toxicity is derived from its food, which consists mainly of insects (3) (5).
The breeding behaviour of the Cainarachi poison frog is, as yet, undescribed. However, male poison frogs tend to be fiercely territorial and engage in competitive vocal displays, calling loudly from conspicuous positions to attract spectating females. Once paired up, the male leads the female to a moist, streamside cave where the small clutch of eggs is subsequently laid. The male then fertilises the eggs and may then guard them until the tadpoles are developed. Once hatched, the tadpoles are carried on the back of the male to a stream, where they are deposited, and over time the tadpoles will undergo metamorphosis to become adult frogs (3) (4) (5) (6).Top

Cainarachi poison frog threats
Known from fewer than ten locations, the Cainarachi poison frog is extremely vulnerable to any destructive activities within its small range. However, unfortunately for this little-known species, much of its habitat is very close to human settlements, and forest conversion to coffee plantations, and firewood collecting and livestock grazing all threaten its habitat (1) (6). Thankfully however, there does not appear to be a demand for the Cainarachi poison frog in the international trade for pets, offering the species some sanctuary from the exploitation that has afflicted other rare amphibians (1) (8) (9).Top
Cainarachi poison frog conservation
With such a small range, the survival of the Cainarachi poison frog is bound to the future management of its habitat. As this Vulnerable frog does not occur in any protected reserves, measures must be taken to safeguard the areas in which it is found (1).Top
