Blue Coral Snake Juvenile: Singapore Nature 2022

We found this highly venomous young Malayan Blue Coral snake, Calliophis bivirgatus, whilst herping in the Central Catchment Forest , Singapore June 2022. It was unusual to find it out early evening. Thanks to John as usual for his eagle eyed spotting.

Family : ELAPIDAE, Species : Calliophis bivirgatus, Maximum Size : 1.8 metres

The Blue Malayan Coral Snake is a beautiful, but highly venomous, front-fanged elapid. It inhabits primary and secondary forest, in lowland and lower montane areas.

In common with many other elapids in Southeast Asia, its primary food source is other snakes.

It dwells amongst the leaf-litter on the forest floor, but seems to emerge early to mid-morning especially when night-time rain has made the leaf litter wet. Typically this snake is encountered crossing forest trails.

It is instantly recognisable by its red head, tail and belly. The dorsal surface is dark blue to black, and most populations have a broad blue stripe on each flank. Care should be taken not to mistake this species for the Pink-headed Reed Snake Calamaria schlegeli, however.

This snake generally flees when disturbed, but at other times may remain coiled on the ground with its tail erect as a warning.

There are 3 sub-species :

(i) C. b. bivirgatus which inhabits Java (this subspecies lacks blue stripes on the flanks).
(ii) C. b. flaviceps which occurs in Myanmar, southern Thailand, Laos, Cambodia, Peninsular Malaysia, Singapore, Sumatra and various islands of the Riau Archipelago (this subspecies possesses a blue stripe on each flank).
(iii) C. b. tetrataenia in Borneo (this subspecies has a cream stripe on each flank, and no blue stripe). (ecology asia)
