Pictures and information about Cobra Snake

Today I will share something about animals. And this kind of animals is a dangerous one. According to the bible a snake is a creature that being punished by God. In the story of Adam and Eve when God created them. God put them into the paradise and said to them to live according the law of God. Eve was tempted by Satan by using the snake ement to tempt Eve to eat the fruit from the garden. God told them to live according to his rules and not eat the single fruit at the garden which is apple. So here I hope you enjoy to read the article I share today.

A cobra (About this sound pronunciation (help·info)) is a venomous snake, which is a member of the family Elapidae (elapids). The name is short for cobra de capelo, which is Portuguese for "snake with hood," or "hood-snake. When disturbed, most of these snakes can rear up and spread their neck (or hood) in a characteristic threat display. However, not all snakes referred to as cobras are of the same genus, or even of the same family.

Cobra may refer to:

* Any member of the genus Naja, also known as typical cobras (with the characteristic ability to raise the front quarters of their bodies off the ground and flatten their necks in a threatening gesture), a group of venomous elapids found in Africa and Asia.
* Any member of the genus Boulengerina, a.k.a. water cobras, a group of venomous elapids found in Africa.
* Any member of the genus Aspidelaps, a.k.a. shield-nosed cobras or coral snakes, a group of venomous elapids found in Africa.
* Any member of the genus Pseudohaje, a.k.a. tree cobras, a group of venomous elapids found in Africa.
* Paranaja multifasciata, a.k.a. the burrowing cobra, a venomous elapid species found in Africa.
* Ophiophagus hannah, a.k.a. the king cobra, a venomous elapid species found in India and southern Asia.
* Hemachatus haemachatus, a.k.a. the spitting cobra or ringhals, a venomous elapid species found in Africa.
* Micrurus fulvius, a.k.a. the American cobra or eastern coral snake, a venomous elapid species found in the southeastern United States.
* Hydrodynastes gigas, a.k.a. the false water cobra, a mildly venomous colubrid species found in South America.
* A taxonomic synonym for the genus Bitis, a.k.a. puff adders, a group of venomous vipers found in Africa and in the south of the Arabian Peninsula.

Snakes are elongate legless carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. In order to accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.

Living snakes are found on every continent except Antarctica and most islands. Fifteen families are currently recognized comprising 456 genera and over 2,900 species.They range in size from the tiny, 10 cm long thread snake to pythons and anacondas of up to 7.6 metres (25 ft) in length. The recently discovered fossil Titanoboa was 13 metres (43 ft) long. Snakes are thought to have evolved from either burrowing or aquatic lizards during the Cretaceous period (c 150 Ma). The diversity of modern snakes appeared during the Paleocene period (c 66 to 56 Ma).Most species are non-venomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom potent enough to cause painful injury or death to humans. Those which are non-venomous either swallow prey alive or kill it via constriction.

Evolotion - he fossil record of snakes is relatively poor because snake skeletons are typically small and fragile, making fossilization uncommon. However 150 million-year-old specimens, readily identifiable as snakes, yet with lizard-like skeletal structures, have been uncovered in South America and Africa.There is consensus, on the basis of comparative anatomy, that snakes descended from lizards. Fossil evidence suggests that snakes may have evolved from burrowing lizards, such as the varanids or a similar group during the Cretaceous Period. An early fossil snake, Najash rionegrina, was a two-legged burrowing animal with a sacrum, and was fully terrestrial.One extant analog of these putative ancestors is the earless monitor Lanthanotus of Borneo, although it also is semi-aquatic.Subterranean forms evolved bodies that were streamlined for burrowing and lost their limbs.According to this hypothesis, features such as the transparent, fused eyelids (brille) and loss of external ears evolved to cope with fossorial difficulies such as scratched corneas and dirt in the ears. Some primitive snakes are known to have possessed hindlimbs, but their pelvic bones lack a direct connection to the vertebrae. These include fossil species like Haasiophis, Pachyrhachis and Eupodophis, which are slightly older than Najash.
