Dubois' Sea Snake (Aipysurus duboisii)

Ranging across coral reefs of the Coral Sea, Arafura Sea, and western Australia, Dubois' Sea Snake is the most venomous sea snake on earth and the third most venomous snake overall. Operating with an ultra-potent subcutaneous murine LD50 of 0.044 mg/kg, its venom contains both postsynaptic neurotoxins and severe myotoxins that break down skeletal muscle tissue and flood the kidneys with myoglobin. The most venomous sea snake on Earth, equipped with dual neurotoxic and muscle-dissolving myotoxins. Ranks #6 beneath Funnel-Web Spider because sea snakes possess docile temperaments and rarely inject full venom when biting humans defensively, but outranks Deathstalker Scorpion in pure laboratory LD50 lethality.
