Meet the white-spotted bush frog, a species that is fascinating on several counts. For one, it breeds inside bamboos (yes, in the hollows of the fast growing woody grasses).
To convince a female to have kids with him, a male frog first finds a nice spot – a bamboo stem with a tiny hole just big enough to get through – and then sings to impress.
If a female likes it, she enters the bamboo, lays her eggs and immediately calls it quits. Daddy babysits alone (and mamma moves on to make more babies).
While daddy does his duty, he aggressively croaks to warn other male frogs against stepping on his patch.
And with good reason: rival males can make a quick meal of his eggs. They are hungry and, it turns out, cannibals. Eggs, as is obvious, are rich in nutrients and if left behind by their dad, have little chance of survival. Scientists recently uncovered these aspects of the bamboo-breeding frogs using an endoscope – a medical device typically used to peer inside our bodies.
What makes matters worse for the frogs, besides cannibalism, is that they are a critically endangered species existing nowhere but in India’s Western Ghats, a chain of mountains alongside the country’s west coast.
And given the harvesting pressure facing their bamboo nursery, the frogs need all the help they can get. Finding out where the frogs live outside of reserves can identify bamboo stands worth protecting. Another useful thing would be to stop cutting down bamboo during monsoons, which is when the frogs breed. You can do your bit by spreading the word on a more detailed piece I wrote about these frogs for Mongabay-India.
