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 Taipan (Oxyuranus scutellatus) is Australia's most notorious snake, and the longest of the venomous snakes. It can grow up to 3m, the average taipan is 2,5 m. Before the development of antivenom in the 1950s bites from the taipan where mostly fatal.
