snake eyes
snakes do not see colors but their eyes are equipped with a combination of light receptors rods that provide low light but fuzzy vision and cones that produce clear images the complexity of the eyes vary among species because of their different lifestyle. the snake looked like legless lizards means that is jelly-like that cannot be kept some snakes are very slippery because of their long shape snakes organ are arranged linearly but they are otherwise similar to those of other vertebrates including people the bone encased brain and sensory organs are contained in the head and snakes have almost all the senses that do.
snakes movements
hearing – although snakes are not equipped with outer ears like people sound waves from the air hit their skin and are transformed from muscle to bone. when the sound reaches the ear bone beneath the skull it sends vibrations to the inner ear and the sound is processed by the brain.
sight – snakes do not see colors but their eyes are equipped with a combination of light receptors rods that provide low light with blurred vision.
smell- snake breathe through their airborne smells into nasal openings that lead to an olfactory chamber for processing but snakes have a secondary system as well when a snake flicks its tongue it’s gathering small particles for that they transfer it into a fluid.
there are 2700 known snake species and the reptiles all have the same characteristics are;
- they have thin linear and limbless bodies.
- they are meat eaters [carnivores].
- they are cold-blooded their inner temperature varies with the temperature in the environment.
snake range from 4 inches to more than 30 feet in length hundreds of tiny vertebrate and ribs span this distance and connect to each other through an intricate system of muscles creating unrivaled flexibility an extremely elastic skin attaches to the muscles and is covered with scale made of keratin the same substance as human fingernails. the scales are produced by the epidermis the outer layer of skin. as the snake grows the number and the pattern of its scale stay the same although a snake scales are shes many times over the course of its life. people who shed worn-out skin constantly in tiny pieces snake shed all of their scales and outer skin in one piece during a process called molting. when the skin and scales start to wear down from the time of injury the epidermis began to create new cells to separate the old skin from the developing inner layer. the new cells liquefy making the outer layer soften when the outer layer is ready to shed the snake scrapers the edges of its mouth against a hard surface such as rock until the outer layer begins to fold back around its head it continues scraping and crawling until it is completely free to the dead skin which takes about 14 days is repeated from anywhere from a few days to a few month. snakes grow quickly until they reach maturity which takes one to nine years however their growth much slowed their maturity never stops its a phenomenon known as indeterminate growth. depending on the species snakes can live from four to more than 25 years.
