Snake characteristic can divide into four that is anatomy, locomotion and limblessness, predation and reproduction
Anatomy:
- In most snakes limbs are entirely lacking, but a few have traces of hind limbs.
- It also have a skin that covered by horny scales and will extract from their body several times a year.
- Snake have good vision. There are no movable eyelids.
- They do not hear airborne sound waves, but can perceive low-frequency vibrations (100–700 Hz) transmitted from the ground to the bones of the skull.
- Snake did not have any vocal chords but only can made a hissing sound.
Locomotion and Limblessness:
- A snake moves by means of muscular contraction, which can produce several types of locomotion.
- It is believed that snakes are descended from lizards.
- Some paleontologists have held that limblessness was an evolutionary advantage in the dense vegetation that formed the early environment of snakes.
Predation:
- Small snakes feed on insects and larger ones on proportionately larger animals.
- Snake teeth was design only for catching and holding not for chewing so that why snake will swallow the animal and not chew it first before swallow it.
- Some snake will capture animals by pinning them on the ground.
- squeezing is also one of the ways that snake can make to kill the animals.
- inject venom that they produce by modified salivary glands is also a ways to kill animals.
- Snake also will attack person when they think that they are threatened.
Reproduction:
- Fertilization is internal in snakes. It is because it same with lizard have a copulatory organ to mating with their partner.
- Females of some species can store sperm for several years to insure future fertilization.
- Some species lay their egg and some species hatching their eggs in their body.
- Some egg-laying snakes brood the eggs, but there is no parental care of the young.
