No Mundo da Biologia e Ciências: BIODIVERSIDADE DOS ANFIBIOS

Menores Anfíbios do Mundo

Um dos menores vertebrados anfibios do mundo foi descrito na Índia por SD Biju e seus colegas. Tem hábitos noturnos. A vida deste sapinho está sobre serapilheira e entre as raízes de samambaias da floresta tropical úmida de Western Ghats de Kerala, uma região montanhosa no oeste da Índia. Biju deu um novo nome para o sapo, Nyctibatrachus minimus.
Os machos adultos tem apenas 10 mm de comprimento, É um dos sapos em miniatura dentre outras partes do mundo, incluindo Cuba, a Amazônia e Borneo.
A descoberta foi publicada recentemente na revista Science atual. Esta rã minúscula indiano sentado em uma moeda rupia indiana 5 é o menor sapo Índia.

Ao lado vemos uma espécie nova de rã amarela que foi encontrada nas montanhas do oeste do Panamá. Pertence a um rico grupo de espécies de anfibios, os rainfrogs, que não possuem uma fase de girino, mas desenvolvem diretamente como pequenos sapos dentro do ovo.

Red-eyed tree frog. Amphibian populations are declining worldwide, principally because of the spread of the fungal disease chytridiomycosis. Researchers know that some amphibian populations and species are innately more susceptible to the disease than others.
