Where are the hot eyes of rattlesnakes?

Rattlesnake is a kind of tube-toothed venomous snake of the family Agkistrodon halys. The snake venom is a blood venom. It generally has a body length of about 1.5 centimeters. It is yellowish green and has diamond-shaped black brown spots on its back. It is named because there is a string of horny rings at the end of the tail that can make a loud sound for a long time so that the enemy does not dare to approach or be scared away. Let's take a look at where the hot eyes of rattlesnakes are.

Where are the hot eyes of rattlesnakes?

The "hot eyes" of snakes such as rattlesnakes and Agkistrodon halys grow in a place called the buccal fossa between the eyes and the nostrils, which is generally 5 mm deep and only one centimeter long. The cheek pit is a trumpet-shaped, with the trumpet mouth facing forward, which is divided into two parts by a thin film. The inside part has a thin tube that communicates with the outside world, so the temperature inside is the same as that of the surrounding environment where the snake is located. And the outside part is a heat collector. If there is a hot object in the direction of the trumpet mouth of the rattlesnake's hot eyes, infrared rays pass through here to the outer side of the film, which is obviously hotter than the inner side of the film, and the nerve endings covered in the film feel the temperature difference. Bioelectric current is generated and transmitted to the snake's brain.

Do rattlesnakes bite after death?

Rattlesnakes are poisonous enough to kill people who have been bitten, but postmortem rattlesnakes are just as dangerous and can bounce and attack even within an hour after death. Rattlesnakes have a reflex in biting and are not affected by the brain. The head of a rattlesnake has special organs that can use infrared to sense feverish animals nearby. The ability of rattlesnakes to bite after death comes from the reflex of these infrared sensing organs. Even if other body functions have stopped, as long as the sensory organs and tissues of the head are not rotten, the rattlesnake can still detect heat-emitting organisms within 15 centimeters of the nearby area within an hour after death and automatically respond to attacks.

How toxic is the rattlesnake?

Humans have severe tingling and burning sensations immediately after being bitten by rattlesnakes, such as the bite of large insects, followed by fainting, but these are only early symptoms. The time of dizziness and stubbornness is as short as a few minutes and as long as a few hours. After regaining consciousness, the body feels heavier, the bitten part swells purple-black, the body temperature rises, and hallucinations begin, and all objects in the line of sight are of one color (most of them are maroon or maroon purple). Any rattlesnake bite should be treated as a life-threatening emergency and immediately sent to hospital for treatment by a professional doctor.
