New Caledonian Sea Krait

Overview

The New Caledonian sea krait is a semi-aquatic, venomous marine snake native to the southwestern Pacific. It exhibits distinctive dark banding along its body and belongs to a specialized lineage of sea kraits that bridge marine and terrestrial ecosystems.

Distribution & habitat

This species is endemic to the waters around New Caledonia and the Loyalty Islands. Being semi-aquatic, individuals split their time between the ocean and coastal land environments, frequently moving into intertidal zones, coastal vegetation, and elevated terrestrial areas to bask or seek shelter in rock crevices and tree cavities.

Biology & behavior

Unlike fully marine snakes, sea kraits retain broad ventral scales suited for locomotion on land, where they are agile and capable of climbing trees or navigating rocky shorelines. Females generally spend more time on land than males, a pattern often linked to reproductive needs.

Feeding

Foraging takes place primarily at night in shallow coastal waters and coral reefs. Their diet consists almost exclusively of non-spiny, eel-like (anguilliform) fishes, with particular preference for species such as the lipspot moray.

Reproduction

Like other members of its genus, this species is oviparous, returning to land to lay its eggs.
