Tropical Indo-Pacific


Alternating black and blue grey bands of about equal width, yellowish-cream bar extends across head, lips black, unlike similar Laticauda colubrina (Banded Sea Krait) which has white lips. Both sea krait species occur as vagrant individuals in Australia but are common in adjacent countries.


Max Size: 136 cm

Sea Temperature Range: 25.4-29.1°C

Depth: 0-80m

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Least Concern

Occurrence: Widespread (66.7% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Solitary (1 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
