Kihansi toad is released to the wild

- About 2000 Kihansi waterfall toads have been reintroduced to Kihansi Gorge in Tanzania after the animal was declared extinct in the wild. This is the first example of an extinct declared species of amphibian that returns to its natural habitat, according to a statement from the Wildlife Conservation Society (WCS), a group Environmental officials are at the forefront of efforts to bring the toads to their 'home'.

The tiny Kihansi toad is yellow with pale, almost translucent white skin on the abdomen, making it almost impossible to see its intestine. This toad belongs to a group of unique amphibians that give birth to babies instead of laying eggs, and after they give birth they will carry their offspring.

In 1996, it was first discovered that these tiny toads lived near the end of the Kihansi Gorge waterfall.

This toad was discovered when humans started building a hydroelectric dam on the river that now supplies water to Tanzania. But this dam has reduced the number of toads quickly. In an effort to preserve them, 500 toads have been transferred to the New York Bronx Zoo. However, the number of them continued to decrease in Tanzania until being declared extinct in nature in 2009.

Then, together with the efforts of animal conservationists, the number of toads increased gradually in the laboratory.

In 2010, about 100 toads were transferred to a propaganda center in Dar es Salaam, Tanzania's commercial capital. Scientists have bred and multiplied the quantity to ensure the amount of release of this toad in the natural environment.

Scientists say a system of artificial nozzles has been jointly invested by the Tanzanian government and the World Bank to create a suitable environment for this toad to revive. The toads released back to their natural environment will be closely monitored, scientists will monitor to ensure favorable living conditions for their development.

The cause of this species' extinction in nature is still being debated. However, scientists hypothesize that the combination of habitat change, pesticide exposure and the emergence of infectious chytrid fungi leads to their extinction. Chytrid fungi are the cause of alarming decline and extinction of amphibians across the planet.
