can banded sea krait kill you

Yes, a banded sea krait can kill you. Its venom is highly neurotoxic and is estimated to be about 10 times more potent than that of a rattlesnake or a cobra. The venom attacks the nervous system, potentially causing symptoms such as convulsions, paralysis, cardiac failure, and death. Although these snakes are generally docile and non-aggressive, they can bite in self-defense when threatened, especially if caught or handled. Fatal bites to humans are rare but have been recorded, mainly when a person is bitten after accidentally disturbing or handling the snake. Prompt medical treatment with antivenom is critical after a bite due to the venom's potency and the risk of paralysis leading to respiratory failure.
