How can the poison dart frog adapt to survive in the tropical rainforest?
Enviroment
Temperature
The temperatures don’t even change much between night and day. The average temperature in tropical rainforests ranges from 70 to 85°F (21 to 30°C). The environment is pretty wet in tropical rainforests, maintaining a high humidity of 77% to 88% year-round. The yearly rainfall ranges from 80 to 400 inches (200 to 1000 cm), and it can rain hard.
Land
A tropical rain forest is simply an area of tall, mostly evergreen trees and a high amount of rainfall. The largest tropical rainforests on Earth surround the Amazon River in South America and the Congo River in Africa. The tropical islands of Southeast Asia and parts of Australia support dense rainforest habitats.
Animals
Rainforests are populated with insects (like butterflies and beetles), arachnids (like spiders and ticks), worms, reptiles (like snakes and lizards), amphibians (like frogs and toads), birds (like parrots and toucans) and mammals (like sloths and jaguars). Different animals live in different strata of the rainforest.
Location
Tropical rainforests are mainly located between the latitudes of 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn)—the tropics. Tropical rainforests are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.

Predators and Prey
Poison dart frogs are insectivores, preferring to eat ants and other small insects that they can hunt among the leaf litter of the forest floor. It is believed that the toxins in the frogs’ bodies may be related to the type and amount of insects that they consume.
Poison dart frogs only have one predator, The Fire-Bellied Snake, which has resistance to the toxins produced by poison dart frogs.
Protection
Many poison dart frogs secrete lipophilic alkaloid toxins such as allopumiliotoxin 267A, batrachotoxin, epibatidine, histrionicotoxin, and pumiliotoxin 251D through their skin. This protects them from most animals, as the animals would die if they bite the frog.
Adaptations
The bright blue color of this frog's skin warns predators not to eat it. Blue Poison Dart Frogs are covered with a sticky skin that helps to hold in moisture and allows the tadpoles to cling to the adults while being moved between locations. They have adapted like this to survive in the tropical rainforest.
