no it is in the nasal cavity when looking for prey
Their tongue and the Jacobson's organ.
A snake uses its tongue like a sensor, its can taste the air and determine if there is prey or predators near.
It is prey for snakes and birds of prey. If you're looking for what it eats, it eats insects, berries, seeds, and fruits.
Rattle snakes are their prey.
They do that to 'taste' the air around them - which serves to let them know where any potential prey or predators are. The two tips to the snakes tongue receive scent particles at slightly different times - enabling the snake to determine which way to go to get closer to prey - or further away from predators. When the snake withdraws its tongue into its mouth, it places the tips into a special area of cells on the roof of the mouth - called "Jacobson's Organ" this passes information to the the snakes brain.
No, no vertebrates have ever developed antennas. However, the snake's tongue behaves like an antenna in that it is forked and can sample the air (drawing the scent back into its mouth to do this as the tongue flicks in and out) with enough sensitivity to stalk prey. It can do this because its tongue is forked and it can differentiate the strength signal across the distance of the fork.
A Snake tracks it's prey by flickering its tongue. This is how a snake smells its prey. Most vipers use their tongue as well as their heat sensitive pits located near their eyes. This allows them to detect variations in temperature. A snake does not have a nose to smell nor are they able to hear, as all snakes are def.
Assuming you mean 'why do snakes flick out their tongue'... It's basically a sensory organ. The snake is 'tasting' the air. Each side of the the fork is independent from the other. When the snake flicks out its tongue, it collects microscopic scent particles from the air. Withdrawing the tongue into its mouth, there is a sensitive group of nerves in a 'pocket' where the snake inserts the tips. This translates the scent into messages for the snakes brain. The minuscule difference in strength of the scent on either side of the tongue enables the snake to follow the stronger scent to locate its prey.
they prey for lots of snakes like rattle snakes
cats, snakes, and birds of prey
Birds of Prey, other snakes.
One forked tongue is one of the snakes by the dinosaur and the other is one of the blue monsters snakes tongue.
