The Equatorial spitting cobra (Naja sumatrana) also called the Malayan spitting cobra, golden spitting cobra, Sumatran spitting cobra, or Palawan spitting cobra, is a species of spitting cobra found in Southeast Asia. This species is medium in length, averaging between 0.9 to 1.2 metres (3.0 to 3.9 ft) in length, though they can grow up to 1.5 metres (4.9 ft). The body is compressed dorsoventrally and sub-cylindrical posteriorly. The head of this species is elliptical, depressed, and slightly distinct from the neck with a short, rounded snout and large nostrils. Eyes are medium in size with round pupils. Dorsal scales are smooth and strongly oblique. This species of cobra has no hood marks and colouration varies based upon geographical location. There are two colour phases: a yellow form commonly found in Thailand and Northern Peninsular Malaysia, and a black form found in Peninsular Malaysia, Singapore, and the islands where it occurs in Indonesia and the Philippines. Juveniles and adults also tend to be of different colour.
19-27 rows around the hood (normally 21–25), 15-19 just ahead of the mid-body; 179-201 ventrals, 40-57 subcaudals; basal subcaudals... Wikipedia →

With luck
About 10% of wildlife watchers report an Equatorial Spitting Cobra sighting in Singapore on a given day, based on 156 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 64 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report an Equatorial Spitting Cobra in Singapore on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Equatorial Spitting Cobra sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Equatorial Spitting Cobra sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Equatorial Spitting Cobra is recorded against all the reptiles logged in Singapore (156 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
