#GOLDEN BLACK FROQ SKIN#

The last record of a wild Panamanian golden frog was made in 2009. Their secretions are the most toxic of any member of the Bufonidae family.

#GOLDEN BLACK FROQ SKIN#

In studies it has been shown that the toxins from their skin could kill over a 1,000 mice. In captivity they do not produce this toxin. This blocks the sodium channels in the animal and affects potential predations. The nerve toxin that they produce is called “zetekitoxin” after their scientific name. The brightly colored skin serves to warn potential predators that the frog is very toxic and would be dangerous for them to eat. Most predators can not consume these animals due to the toxin they produce but some species appear to have developed a resistance to this. Natural predators of the Panamanian golden frog include birds, snakes and fish. What is impacting the survival of the Panamanian Golden Frog ? They appear to “wave” their hands or move their feet to greet each other, attract a mate or to defend their territory. They use a form of sign language called semaphore in order to signal to each other. They do however use another form of communication similar to what is used by deaf humans. This behavior seems odd because the frogs have no eardrums and the rivers near where they live can be very loud. These calls are loud enough to be heard from their home by the streams into the forest. The male Panamanian golden frog is known to make a whistling sound and at least two different types of calls. These animals will be active during the day. What does the Panamanian Golden Frog do with its day? Sexual maturity is reached by two years old. The juvenile frogs stay more hidden as they do not have the coloration to protect them from predators, as they eat insects and invertebrates they develop the yellow and black color and build up their toxin levels. Tadpoles are equipped with a sucker on the abdomen which helps them to hold on to objects in fast moving water. They will stay as tadpoles for roughly four to eight months before they develop into frogs. When they hatch they are a white or sandy color to match the bottom of the stream. Their large clutch size helps to increase the chance that some will reach their adult size. As she lays the eggs the male fertilizes them and after about 6-9 days later tadpoles will hatch out. She will lay a long strand of eggs (from about 200 to about 600 eggs) which are attached to a rock or pebble and sheltered from the sun. When a female crosses a males path the male will climb on her back, the female will then find a shallow place in a stream.

How does the Panamanian Golden Frog produce its young?īetween November and January female frogs will return from the forest to the streams where the males will have been marking out territory. The more different kinds of invertebrates and insects that the frog eats, the more toxic its skin secretions get. It is the frogs diet that help makes them toxic even to the touch. Panamanian golden frogs in the wild eat a wide variety of invertebrates such as beetles, flies, ants, springtails, caterpillars, wasps and spiders. What does the Panamanian Golden Frog eat? Animals found in areas of wet forest are typically larger than those in dry forest. The females are larger than the males, up to 25% longer and heavier. The average body length of the female is 4.5-6.3cm (1.7-2.5in) with the average weight being 4-15 grams (0.14-0.5oz). The average body length of the male is 3.5-4.8cm (1.4-1.9in) with the average weight of the male being 3-12 grams (0.1-0.4oz). Like other frogs and toads, the golden frog is capable of secreting a poison to help protect themselves from predators. No spots are present on the underside.Įach frog has an individual pattern which helps to tell them apart.Īlthough known as a frog and having the smooth skinned appearance and looking like a frog it is actually classified as a “true toad” (Bufonidae). They will also usually have several black splotches on their back and legs, although some of them have no black at all. What does the Panamanian Golden Frog look like?Īdult males and females have similar coloring.
