Why is very little known about Malabar torrent toads?

 The Malabar torrent toad is a small toad. It is black, with grayish spots on the head, and bright yellowish spots on the underside. It is found in the ever-green forests of the Western Ghats, in small rocky streams. The tadpoles are black in colour, and have sucker shaped mouth discs that are adapted for life in the rapid mountain streams. These toads are very rare indeed, and so very little is known about their life history.
