Nyctibatrachus major
species of amphibian
Nyctibatrachus major, the Malabar night frog, large wrinkled frog, or Boulenger's narrow-eyed frog, is a species of frog in the family Nyctibatrachidae, commonly known as the robust frogs. It was described in 1882 by the zoologist George Albert Boulenger, and is the type species of the genus Nyctibatrachus. It is a large frog for its genus, with an adult snout–vent length of 31.5–52.0 mm (1.24–2.05 in) for males and 43.7–54.2 mm (1.72–2.13 in) for females. It is mainly brownish to greyish in colour, with a dark greyish-brown upperside, a greyish-white underside, and light grey sides. It also has a variety of grey or brown markings. When preserved in ethanol, it is mostly greyish-brown to grey, with whitish sides. Sexes can be told apart by the presence of the femoral glands (bulbous glands near the inner thigh) in males.
The species is endemic to the Western Ghats mountain range of India, where it is found in Kerala, Tamil Nadu, and Karnataka. Adults inhabit fast-moving forest streams at elevations of up to 900 m (3,000 ft) and have highly specific habitat requirements. Adults are mostly found in or near water and are nocturnal; subadults can be found during both the night and day.
This brief starts where responsible research should: with the source description of “Nyctibatrachus major” as species of amphibian. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of amphibian. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q2244429. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1882.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
