Animal Description
  • Poison arrow frogs are also called poison-dart
    frogs because some of the Amerindian tribes use
    their secretions to poison their darts.
  • Not all arrow frogs are deadly, only three
    species are very dangerous to humans.
  • The most deadly species to humans is the
    Phylobates terriblis. Arrow frogs are not
    poisonous in captivity.
  • Cutaneous chytridiomycosis was documented for the
    first time as a vertebrate parasite.
  • The same antifungal that is used to kill
    athletes foot in humans can be used with the
    frogs and toads.
  • Poison arrow frogs are known for their beautiful
    colors.
  • These colors are used as warnings to predators
    that they are poisonous (their poisonous defense
    evolved to ward off predators.)
  • Some scientists think that the reticulated
    pattern of the frogs also act as camouflage among
    the forest shadows.

Habitat Description
  • These frogs are found in Columbia along the
    western slopes of the Andes.
  • Poison frogs live in the rainforests of Central
    and South America.
  • auratus is found on the Pacific coast from
    southern Costa Rica to northern Columbia and on
    the Caribbean coast of southern Nicaragua to
    Columbia and the island of Tobago.

4
Food
  • Both feed mostly on spiders and small insects
    such as ants and termites, which they find on the
    forest floor using their excellent vision.
  • They capture their prey by using their sticky,
    retractable tongues.
  • They are fed small crickets daily.

5
Protection
  • They protect themselves by deceive theyre
    predator with their beautiful colours.
  • They use theyre color to remind the predator
    that they are poisonous.
  • Poison dart frogs protect themselves best simply
    by being deadly to consume. They are
    dendrobatids, part of a family of animals
    that includes some of the most toxic
    species on the planet.

6
Birthing Process
  • The mating season for auratus occurs throughout
    the entire rainy season from mid-July through
    mid-September.
  • Male frogs go through an elaborate ritual to
    attract mates. The males vocalize, a trill sound,
    to attract females. The female lay up to 40 eggs
    on leaves. The eggs are encased in a gelatinous
    substance for protection against desiccation.
  • During the two-week development period, the male
    returns to the eggs periodically to check on
    them. Once the tadpoles hatch, they swim onto the
    males back and he carries them to a place
    suitable for further development, such as wet
    holes in broken trees and branches, little ponds,
    wet coconut-shells, and even in tin cans and car
    tires.
  • The tadpoles are attached to the males back by
    a mucus secretion, which is soluble only in water
    so there is no chance for them to fall off. Once
    at their final destination, the tadpoles are on
    their own. They need an additional three months
    to metamorphose into small frogs.

Fascinating or Unique
Characteristic
  • Most species of poison dart frogs are small,
    sometimes less than 1.5 cm. In adult length,
    although a few grow up to 6 cm.
  • The only animal that can kill with just a touch.
    The toxin is not in the tongue or fangs. but in
    the skin glands.

8
Problems
  • European and American collectors prize the
    brightly colored poison dart frogs, resulting in
    a high demand in the international pet trade for
    new and increasingly rare specimens.
  • Wild poison dart frogs are protected by treaty,
    but that increases their value to smugglers, who
    export them illegally to capitalize on the
    demand.
  • Smugglers hide these little frogs in luggage, or
    concealed in legal shipments of exported tropical
    fish.

9
Conclusion
  • I like this animal because the color is beautiful
    to see.
  • I dont like this animal
    because it have a toxin and
    its poisonous.
  • I also like this animal
    because is small and cute.
