Adaptations for Poison Dart Frogs
Transcript of Adaptations for Poison Dart Frogs
By : Genevieve Stockwell
These frogs are very small. Most are smaller than a quarter. This helps them hide in small spaces and under leaves.
Different from other frogs, the Poison Dart frog doesn't have markings to camouflage it's body. They can be brightly colored in red, blue, yellow, green or black, and can have stripes, spots or patterns. The brighter the colors, the more poisonous it is.
Where Do They Live?
Poison dart frogs can live from of Costa Rica to Brazil. They like wet places in the rain forest.
This is helpful because most animals know they are poisonous so these frogs are less likely to get eaten.
One final physical adaptation is that their feet have suction cups.
This helps them climb vertically to get the best roosting and calling spot.
Male dart frogs defend their territory very aggressively so they have better access to food and safety.
Another adaptation is their skin is poisonous. The frogs eat poisonous ants and insects, then the toxins build up in the frog's skin mucus.
This is how this frog got it's name. Tribemen would put the poison from the frog's skin on the tips of their blowdarts used for hunting.
Males tend to have the brightest colors. Females are attracted to the males who are most colorful.
Poison Dart frogs are devoted parents. They lay their eggs on a leaf or in the moss, then will carry the tadpole on their back to water.
Another behavioral adaptation is the way they care for their babies.
If rainforests warm up, not as much rain falls. Then plants that need a lot of water die. This means that the insects and animals that live there, like the Poison Dart frog, cannot survive.
