Snails are largest Mollusk subgroup containing 10,000 species and 400 dwelling households. Globally they’re distributed in each habitat, beneath water and on land. Most aquatic and marine animals are benthic through which few are swimmers. It encompasses myriad of life from predators to algae grazers and unimaginable variety of type. Often the shell is coiled however not all the time in the suitable handed course. An operculum can also be current typically, a door that matches in opening of coiled valve and shutting animal inside for protection. Some snails have complete shell inner and are coated with pores and skin. The teams which lack safety of shell comparable to nudibranches are elaborately coloured which help them to mix with comparable coloured background and warn predators of noxious style.

The meat of snail is taken into account to be top quality meals full of protein and can also be a terrific supply of iron. It incorporates 15% protein, 80% water and 2.four% fats which make it an alternate meals for individuals requiring excessive protein low fats weight-reduction plan. Snail is wealthy in important fatty acids corresponding to linolenic acids and linoleic acids.

Description

Often gastropods have single, spirally coiled shell however shell is lowered or misplaced in some teams. A lot of the snail has operculum, a plate which closes gastropod’s opening. Gastropods (shelled) have mantles and these with out shells have decreased to absent mantles. Most species of Gastropods have muscular meals which is used for creeping. The foot is modified for burrowing and swimming. Gastropods have well-developed head which incorporates eyes at finish of 1-2 pairs of tentacles.

Snails have true coelm, a physique is split into three elements of head, muscular foot and visceral mass and organ techniques for respiration, circulation, excretion, digestion, copy and nerve conduction. Its physique plan has torsion or twisting throughout larval improvement by visceral mass that twists 180 levels in relation to go and bringing mantle cavity to anterior of animal. Renal & anal openings and gills are close to the entrance of animal. Principally snails are herbivorous in nature however many marine species and few land species could also be carnivores or omnivores. Snail makes use of its radula to interrupt its meals. Radula is a chitinous construction which incorporates microscopic hooks often known as cutculae. The snail scrapes at meals with this and then transferred to digestive tract.

Snails have 1-2 pairs of tentacles on heads. In land snails, eyes are carried on the information of first set of tentacles and are roughly 75% of width of eyes. Second set of tentacles operates as olfactory organs. Land snails have each set of tentacles. Snail has cerebral ganglia which type a primitive type of mind that has been divided into 4 sections. This construction is straightforward compared to brains of mammals, birds and reptiles. Snails are in a position of associative studying.

They transfer by alternating physique contractions by stretching with low velocity of 1 millimeter per second. They create mucus to help locomotion by decreasing friction. The mucus additionally lowers the probabilities of damage of snail. They’ve mantle which covers inner organ often known as foot.

Food regimen

In wild, snails eat numerous totally different meals resembling fruits, leafy vegetation, carrion and manure. They create injury to agricultural crops in addition to backyard crops and are thought-about as pets.

Lifecycle

Some species lay eggs which include giant yolk. The eggs improvement may be inside physique or may be expelled externally to develop. Eggs turn into larvae. Whereas larvae, these species develop shell. When animal develops, it provides one other curl of shell ending in a gap from which foot or head of the animal emerge.

Copy

Snails are sexual and some are hermaphroditic which suggests single particular person can produce each eggs and sperm. People trade sperm with different particular person as an alternative of fertilizing themselves.

  1. Protein content material

Snails supply low calorie supply of protein which is required for repairing and constructing muscle mass. It helps to fill higher than fats and carbs.

  1. Presence of Iron

Snails are an ideal supply of iron which is important to construct pink blood cells and for transporting power all through the physique. The deficiency of iron leads to anemia and excessive fatigue. Iron is a element a part of haem teams of carrying oxygen proteins similar to myoglobin and haemoglobin and electron carrying mitochondrial protein cytochrome. Iron has an important position in coupled oxidations or reductions in such course of as oxygen transport or mobile respiration. Iron-sulphur enzymes act as elctrontransferring reactions of mitochondria. Iron is accessible in intracellular cytochrome enzyme system with very important position in power manufacturing in addition to mobile respiration. Actually, iron from animal sources might be absorbed extra compared to greens and cereals because the iron from plant sources are complexes with oxalates and phytates in plant. It makes an excellent supply of iron in weight-reduction plan.

  1. Vitamin B12

Vitamin B12 is required for manufacturing of purple blood cells, maintaining nervous system wholesome and releasing power from meals we eat and processing folic acid. Snails are loaded with vitamin B12.

  1. Magnesium

Snails are an excellent supply of magnesium during which our bodies are required for sustaining regular blood strain, common heartbeat and strengthen bones.

  1. Presence of Selenium

Selenium present in our bodies helps to maintain immune system wholesome and protects cells from injury. Snails include selenium in it.

  1. Supplies power

The crude protein content material was decided with using Soxhlet extraction equipment to extract crude fats completely from four of milled snail pattern utilizing petroleum ether in soxhlet technique of fats willpower. The fats content material weight extracted divided by weight of pattern multiplied by 100% gave % crude fats content material. Ash is decided to be incinerating 5 g of milled snail pattern at 550 oC in a single day in muffle furnace. Weights after and earlier than ashing are used to calculate per cent content material of ash. Drying 2 g of milled snail pattern 105 oC for three h with using thermostatically managed pressured air oven decided moisture content material. Weight distinction after and earlier than drying was used for calculating per cent moisture content material. The obtained complete carbohydrate was 100% by subtracting per cent quantities of crude fats, crude protein, ash and moisture. Snail pattern’s power worth was obtained by multiplying per cent composition of fats, protein and carbohydrate.

  1. Copper

Copper is part of tyrosinase enzyme i.e. important for melanin pigment formation in physique. It is part of lysyl oxidase molecule and different enzyme techniques. Copper has an important position in selling regular perform of connective tissues of bone. Snail meat is a superb supply of copper and is used to fight malformation of bone construction. It stimulates utilization and absorption and synthesis of iron into cytochrome molecules and haemoglobin.

  1. Zinc

Above 80 enzymes comparable to carbonic anhydrase, alcohol dehydrogenase, RNA and DNA polymerases and carboxypeptidase are thought-about to require zinc. The excessive concentrations of zinc in sperm cells, prostate gland and eyes the place it’s assumed to play very important perform and all tissues of physique. Zinc with vitamin A has a task in night time imaginative and prescient and darkish adaptation. Individuals eat snail meat for curing eye issues.

  1. Calcium

About ninety 9 per cent of calcium is current in tooth and bones and one % is present in physique fluids and smooth tissues. Calcium is discovered abundantly in A. achatina. Calcium is required for regular blood clotting. Snail meat fluid is used for stopping bleeding from cuts. The decrease blood calcium degree promotes nervous tissue irritability and low calcium degree causes convulsion. Calcium depress nerve irritability.

Snail is a superb supply of calcium ortho phosphate which is a chemical substrate used to remedy kidney illnesses. The serving measurement of 200 grams of dried snail within the weight-reduction plan provides every day requirement of calcium to lactating and pregnant ladies and additionally youngsters.

  1. Supply of potassium

Potassium is a key intracellular motion and with sodium, it has an important position in regulating water and acid base & electrolyte stability within the physique. Principally, potassium is required for decreasing each diastolic and systolic blood strain in individuals with excessive and regular blood strain. Potassium lowers salt sensitivity which is an unbiased danger issue inflicting coronary heart illness. It affect contractility of skeletal and cardiac muscle tissues and have an effect on excitability of nervous tissue. The deficiency of potassium leads to muscular weak spot, psychological disorientation, elevated nervous irritability and cardiac irregularities.

Precautions
