Yellow-lipped Sea Krait

Laticauda colubrina

☠️ Highly venomous

Description

The Yellow-lipped Sea Krait, Laticauda colubrina, is a strikingly patterned marine snake found throughout the tropical Indo-Pacific region, from Southeast Asia to the islands of the western Pacific. It is easily recognized by its bluish-gray body with distinct black bands and a yellow snout and lips. Adults typically measure 1–1.5 meters in length. Unlike fully aquatic sea snakes, this species is amphibious, spending much of its time in the ocean hunting for eels and small fish, but coming ashore to rest, digest food, and lay eggs. It is an excellent swimmer and can remain submerged for extended periods while foraging among coral reefs.

Venomous?

Highly venomous. The venom of Laticauda colubrina is neurotoxic and potent, used to quickly immobilize prey. However, the species is not aggressive and bites are extremely rare.

A Danger to Humans?

Generally docile and non-aggressive toward humans. It will usually flee if disturbed. Although its venom is dangerous, the snake’s small mouth and calm temperament make accidental envenomation highly unlikely. Caution should still be exercised when handling or encountering this species in the wild.

Population threats​

The major threats to this species may include anthropogenic disturbances such as coastal development and habitat destruction. This includes loss of shore habitats required for laying eggs and digesting prey. This species is attracted to light and may be affected by lighting from hotels and beach shacks in developing areas (A. Lobo pers. comm.). There is anecdotal evidence that resort developments on some Fijian islands may have reduced population sizes of L. colubrina (M. Guinea pers. comm. cited by Marsh et al. 1993).

Population number​

This is a very widespread species. Although there are some threats, these do not appear to be causing significant declines at this time. Sea level rise may become an important threat to this species in the future. This is listed as Least Concern.
