How Jacobson's organ help snakes to sence smell?
A snake's tongue has few taste buds. It is used with an organ of smell called the Jacobson's organ, which, along with the nostrils, provides snakes with a keen sense of smell. The Jacobson's organ consists of two hollow sacs in the roof of a snake's mouth, each of which has many nerve endings that are extremely sensitive to odors. A snake sticks out its tongue to pick up scent particles in the air or on the ground or some other surface. When the snake pulls its tongue back into the mouth, these particles enter the Jacobson's organ. The organ enables a snake to follow the scent trail of its prey.
