This contest is fueled by the following news: A man in East Naples had to learn the hard way that driving a car and playing with a pet animal at the same time is far from a good idea. That is particularly true when the pet in question is an agitated snake. Courtland Page Johnson, age 30, of 1373 Wildwood Lakes Blvd., was driving his PT Cruiser on Golden Gate Parkway at night. While driving, the pet snake wrapped around his neck and then attacked his face, Naples police officials stated following the incident. An onlooker, Charles Page, told police Johnson was driving erratically. He said Johnson crashed into several roadwork barricades. Page said Johnson had a snake in his hand at the time of the crash. Johnson was arrested and charged with leaving the scene of a crash. Additionally, he was taken to the Naples Jail Center. At press time, Police did not know why Johnson was driving with his pet snake around his neck. Additionally, they could not report on the extent of his injuries. Johnson did admit that he panicked while driving when the pet snake bit him.
Snakes (Latin:Serpentes) is a suborder of Serpentes belonging to the Squamata order. Harmless and poisonous snakes, which are dangerous to human as well as for animals, are found amongst a variety of snakes.
Serpentology deals with the study of snakes.
The body is elongated without limbs. The length of the body may vary from 10 cm to 12 meters.
From apodal lizards, snakes are distinguished by movable connections of the left and right sides of the jaw (which enables them to swallow prey whole) and by the absence of mobile eyelids and ear drums and the lack of a shoulder girdle.
Snakes have a diapsid skull but both the temporal arches are absent. From the front side, the cranium has ossification, which protects the brain while swallowing big prey. The skull in the majority of snakes is distinguished by highly developed kinetic movement, i.e, many skull bones are mobile in relation to one another. Quadrates are very mobile and so are the attached temporal and supra maxillary, supra temporal, palantine and pterygoid bones are joined by elastic ligaments with the cranium. Angular, supra-angular and articular bones of the lower jaw are knitted well and a movable joint is present between them and a dental bone. Both halves of the lower jaw are connected with elastic ligament. Such a movable articulated bone system facilitates extremely wide mouth opening, which is necessary for swallowing large prey whole and also ensures the possibility of independent movement of the right and left halves of the jaw while pushing the prey into the pharynx with alternate interception. All this allow the snakes to gulp relatively large prey, which The snakes teeth are on dental, maxillary, pterygoid and sometimes on premaxilla bones. Snake's teeth are sharp and fine, stuck to the edges of maxillary bones or connected with jaw with the help of special ligaments. Venomous snakes have large, sharp, bent-back poisonous fangs on supra maxillary bones. Such fangs have a groove on the front surface or an internal channel, through which the venom gets into a wound on biting. In vipers, the fangs can rotate at 90° due to the mobility of the short maxillary bones. In some cases (Gaboon viper), the fangs reach a length of up to 4.5 cm.
Snakes are distinguished by a large quantity of vertebrae (from 200 to 450).
The breastbone as well as the thoracic cage are not found in snakes and the ribs move apart while swallowing the prey. The shoulder belt is absent in snakes. Rudiments of a pelvic girdle still remain in some primitive snake genus.
The internal organs have an elongated form and are in an asymmetrical position. Apart from this, some of the paired organs have lost the second halve and remained single. For instance, both lungs are developed in most primitive snakes but the right lung is always bigger than the left lung; in the majority of snakes, the left lung completely disappears or is rudimentary. In addition to the right lung, vipers and some other snakes have a "tracheal lung", which is formed by an extended rear portion of the trachea. In the rear portion, the lung itself is transformed into a thin-walled reservoir for air. It is very expansible and the snake can greatly inflate while inhaling and can emit a loud and long hiss while exhaling.
The esophagus of snakes is very muscular and helps in pushing the food into the stomach, which is an elongated bag, translating into a relatively short intestine.
The kidneys are elongated in length and the urinary bladder is absent. Testes are also elongated, the hemipenis of males represents a pair of bags, usually equipped with spinules, which are different with respect to size and shape. These bags lie under the skin behind the anus and turn inside out when the snake is sexually excited. There are four compartments in the oviducts of snakes: the shell, the protein part, egg sac and uterus. With respect to histological structure, the protein compartment of a snake's oviducts is similar to the same compartment of a bird's oviduct but much shorter. Eggs are stored for a very long period in an egg sac. During this period, the egg sac plays the role of incubator: provides eggs with moisture and ensures the respiratory metabolism of the embryo.
