According to the researchers and zoologist, the toads invaded the Brazilian island several decades ago .These innocent toads do not know that they will turn bad on that paradise.
Now almost all of them has undergo deformation of limbs, eyes or mouth parts, some also lack hands or feet too.
Almost half of the toads are either completely or partially blind.
These are lighter in weight than the normal toads and also produced fewer eggs.
It may be due to the tropical effect of the island, scientist are investigating that the deformation may occur due to any parasite, bacterium or a virus attack.
This deformation can lead to their extinction as their body condition is turning bad to worse.
This condition can cause drastic changes in the ecosystem of the island because they play vital role in maintaining the ecosystem of the island.
