[2] The tadpoles of the species are black and form dense and compact schools in slow moving streams in forested areas.

Its head large; snout short, rounded, with well-marked canthus rostralis and concave loreal region ; nostril nearer to the end of the snout than to the eye; interorbital space broader than the upper eyelid; tympanum distinct, nearly as large as the eye.

Skin finely granular above; a moderately prominent, rather narrow glandular lateral fold; another told behind the tympanum down to the shoulder.

Use of this technique in the Bisale Reserve Forest in Kodagu during January 1999 – July 2001 gave a population density estimate of 0.08–0.1 frogs per square metre.

[6] The tadpoles are large (more than 9 cm (3.5 in) in total length) and form shoals in slow moving streams.
