Poison Dart Frogs
Poison dart frogs (Dendrobatidae) are one of Earth's most poisonous species. Scientists believe that they get their toxicity from the insects they eat. Poison dart frogs raised in human care and isolated from insects in their native habitat never become poisonous.
Their coloring can be yellow, gold, copper, red, green, blue or black. This bright range of colors is a defense tactic, warning potential predators that they are toxic.
Their average lifespan is 3 to 15 years.
Poison dart frogs grow to about 1 inch long (about the size of a paperclip) and weight around 1 ounce.
Poison dart frogs live in South America in freshwater habitats.
They are considered critically endangered.
You can see poison dart frogs in our exhibit "Frogs!" which explores the many shapes, sizes, adaptations and colors of frogs and toads - while also presenting the serious threats to amphibians worldwide.
