Just to let you know, this is one of the most venomous snakes in the world.
Locally known as Walo Walo, Sea Kraits are highly venomous. What we have here is the Yellow Lipped Krait. One bite and it delivers a surge of neurotoxins that can cause paralysis and death. You know why it's called Walo Walo locally? Because it is said that its venom can kill a human being in just 8 hours if left untreated.
The rule in the wild is look but don't touch, and always give ample space and respect to the animal.
If it will help you to stay as far as possible from the sea snake in case you spot one, know that most local hospitals, especially in the provinces, are ill-equipped when it comes to treating toxin cases and venom poisoning. Currently, we don't have an extensive library of anti-venins available locally. I don't mince words, I want to say that you may have no choice but dying if you get bitten by a walo walo.
