Snakes
Who would have guessed, right? Contrary to popular perception as snakes being one of the most feared and intimidating animal, they are brought into the human sphere for many interesting reasons. There are numerous species with varying venomous capacity, and thereby the most popular use of a snake, particularly a venomous snake, is to extract its venom for making anti-venom that will be used in case of snakebites. One bizarre use of a snake is for giving snake massages to people, as it possesses smooth scales and will quickly become comfortable with people. Snakes are also increasingly being used to detect oncoming seizures due to their superior sensory capabilities. Snake venom due to its cytotoxic properties, is now being used in cancer research.
