Top 3 Most Toxic Snakes Ranked by Lethal Dose, No Surprise for ‘Sea and Land Duo’
There are several claims about the most poisonous snakes, one of which is the Belcher's sea snake, and another is the Inland Taipan. A documentary previously featured 10 of the most venomous snakes. Sea snakes are still considered more toxic due to the high concentration of venom in seawater due to the salt content. However, sea snakes, because their food consists mainly of fish, have a simpler composition, while terrestrial snakes prey on a wider variety of animals, resulting in a more diverse toxin composition. For mammals, terrestrial snake venom is generally considered more potent. Regarding your question, it's likely the former—sea snakes—are more toxic. I'm also a fellow enthusiast and would be happy to discuss this further.
