These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
The Inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD50 value of 0.025 mg/kg SC. Ernst and Zug et al. 1996 list a value of 0.01 mg/kg SC, which makes it the most venomous snake in the world in their study too. They have an average venom yield of 44 mg.
The most venomous snake, measured by the LD50 test or any type of criteria, is the inland taipan snake of Australia. Image: Inland taipan snake by Wikipedia contributor. The inland taipan (Oxyuranus microlepidotus) possesses the most toxic venom of any snake in the world. But here again, that does not necessarily mean that the inland taipan -- also known as the fiece snake -- is the most dangerous or deadliest snake in the world.
