Head small, body long and slender anteriorly; scales on thickest part of body juxtaposed; 5–6 maxillary teeth behind fangs; 17–21 scale rows around neck, 30–36 around thickest part of body (increase from neck to midbody 18–24); ventrals divided by a longitudinal fissure; prefrontal in contact with third upper labial; ventrals 220–287.
Total length males 950 mm, females 1025 mm; tail length males 80 mm, females 95 mm.
Distribution
Microcephalophis gracilis is found on the coasts of the Indian Ocean and West Pacific, from around the Persian Gulf (Bahrain, Qatar, Saudi Arabia, Oman, United Arab Emirates (UAE), Iran, Iraq and Kuwait) to Pakistan, India, Sri Lanka, Bangladesh, Myanmar, Thailand, and Indonesia, and into the Malay Archipelago/West Pacific in Thailand, Malaysia, Singapore, Cambodia, Vietnam, the Philippines, southern China, Hong Kong, and Taiwan, as well as in Australia (Queensland) and Papua New Guinea.
Venom Characteristics
The venom of this species is dangerous and can be fatal. The symptoms generally began to appear within 30 minutes after being bitten. The bite typically does not cause any pain. Muscles get affected once the venom starts to act causing paralysis which is one of the major characteristics of its bite.
This brief starts where responsible research should: with the source description of “Microcephalophis” as genus of reptiles. 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 genus of reptiles. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 26, 2025. The linked authority identifier is Q5241740. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1025.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
How to read it
