snake animal, sanke reptile
Snake

Snake / sneɪk / (স্নে) n [snake also called serpent, any of about 2,900 species of reptiles distinguished by their limbless condition and greatly elongated body and tail. They do not have legs, voice, ears, and eyelids. Despite this, snakes are successful carnivores. They have a long, slender body, and are very mobile in their own way. Their skin is covered with scales. They can see well enough, and they can taste scents with their forked tongues by flicking them in and out<ভিতর বাহির>. They are very sensitive to vibrations in the ground.

Though they do not have a voice, they can hiss. Most live on the ground, others live in the water, and a few live under the soil. Like all reptiles, snakes need the heat of the sun to control their body temperature. That is why most snakes are in the warm, humid tropical regions of the world. Snakes literally grow out of their skin. Every few months, most start rubbing against the ground or tree branches. Starring at the mouth, a snake slithers out of its too-light skin. Like a sock, the skin comes off inside out.

The coloring of a snake’s skin scales provides an excellent camouflage from predators and prey. Tree snakes can have a color as green as any leaf in the forest; ground snakes are as brown or dusty grey as the earth and rocks, and sea snakes are dark above and light beneath. Snakes attack only when hungry or threatened. When frightened, they tend to flee. If there is no time for a fight, or if snakes are cornered or antagonized, they strike. Venomous snakes have two fangs in the upper jaw that penetrate the flesh of their prey. Poison glands then pump venom through grooves inside the fangs into the prey. Some snakes inject their prey with toxin and wait until the prey is no longer captive<বন্দী> of struggling before eating it.
Snakes have fascinated<মুগ্ধ> and frightened humans for thousands of years. Some cultures still worship snakes, seeing them as creators and protectors<ত্রাণকর্তা>. Others cultures fear snakes as devils and symbols<প্রতীক> of death.] (সাপ; সর্প): Venomous snakes spit and hiss when they are cornered. A snake slithered across the wet road. A snake coiled up in the grass.
<VERB> Snake [to move like a snake, in long twisting curves; to go in a particular direction in long twisting curves] (এঁকেবেঁকে অগ্রসর হওয়া): This road snakes away into the mountains.

They have club-shaped feet with reduced toes adapted for walking on land, and nearly all have high-domed shells. The limbs are covered with hard scales and when the limbs and head are withdrawn into the shell, the animal is completely closed off.
Female tortoises dig nesting burrows in which they lay from one to 30 eggs. Egg-laying typically occurs at night, after which the mother tortoise covers her clutch with sand, soil, and organic material. The eggs are left unattended, and depending on the species, take from 60 to 120 days to incubate. Juvenile tortoises often require a different balance of nutrients than adults, so may eat foods which more mature tortoise would not.
