The red sand boa is a protected species, and looks like it has two heads, because its tail is shaped like its head to help it defend itself.
The snake is prized on the black market because many believe it brings good luck or has medicinal qualities.
Police in Bangalore arrested four people trying to sell the protected creature for $1,500 (£1,100).
Police said plain clothes officers had organised a sting by pretending to be interested buyers.
