The yellow-lipped sea krait (Laticauda colubrina), also known as the banded sea krait or colubrine sea krait, is a species of highly venomous snake found in tropical Indo-Pacific oceanic waters. The snake has distinctive black stripes and a yellow snout, with a paddle-like tail for use in swimming.
It spends much of its time under water to hunt, but returns to land to digest, rest, and reproduce. It has very potent neurotoxic venom, which it uses to prey on eels and small fish. Because of its affinity to land, the yellow-lipped sea krait often encounters humans, but the snake is not aggressive and only attacks when feeling threatened.
The head of a yellow-lipped sea krait is black, with lateral nostrils and an undivided rostral scale. The upper lip and snout are characteristically colored yellow, and the yellow color extends backward on each side of the head above the eye to the temporal scales.
The body of the snake is subcylindrical, and is taller than it is wide. Its upper surface is typically a shade of blueish gray, while the belly is yellowish, with wide ventral scales that stretch from a third to more than half of the width of the body. Black rings of about... Wikipedia →

Possible
About 30% of wildlife watchers report a Banded Sea Krait sighting in Denpasar on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 28 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report a Banded Sea Krait in Denpasar on a given day, against under 5% in October, the lowest month. That is one of Denpasar's wettest months, with about 270 mm of rain against 25 mm in August.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Banded Sea Krait sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Denpasar, in our data
Denpasar is the only city on Wallace's Line with enough records to rate Banded Sea Krait sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Banded Sea Krait is recorded against all the reptiles logged in Denpasar (31 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.
