We are currently home to a couple of species of poison arrow frogs, including the blue poison arrow frog.
Location in the Zoo
Blue poison arrow frogs (Dendrobates azureus) live in French Guiana, Guyana, Suriname and adjacent parts of Brazil and are normally found in lowland forests.
The male and females of this species can be distinguished by the shape of their toes. They both have four toes with enlarged suction cup tips to each toe.
The tips of the male are heart-shaped and the female tips are round. The spots on their backs are unique and can be used to identify individuals, just like a human fingerprint.
Their diet consists mainly of ants, but they will also eat insects and spiders. Their toxicity comes from their diet, just like the Phantasmal poison dart frog
The males fight to win the attention of the female. Females lay between one and thirty eggs. The tadpoles will eat their siblings so they are each taken to different water sources on the back of one of the parents.
Amphibians are one of the most threatened animal groups worldwide. Threats range from over-exploitation for food or the pet trade to pollution, climate change, disease, habitat loss and degradation. As a result, amphibians are often considered to be good indicators to wider ecosystem health.
Information on Africa is patchy, but some countries such as Cameroon have as many as 200 species of amphibians, a third of which are assessed to be threatened by the IUCN (a number which is only likely to increase over time).
