Description of Artemia
Brine shrimp. Artemia were first discovered in Lymington Lymington is a port on the Solent, in the New Forest district of Hampshire, England. It is to the east of the Bournemouth conurbation, and faces Yarmouth on the Isle of Wight which is connected to it by a car ferry. The town has a population of about 40,000 and has a large tourist industry, based on proximity to the New Forest and the harbour.. .....

There are mixed views on whether all brine shrimp are part of one species or whether the varieties that have been identified are properly classified as separate species. Brine shrimp are metabolically inactive as embryos An embryo is an animal or a plant in its earliest stage of development. PlantsIn botany, a plant embryo is part of a seed, consisting of precursor tissues for the leaves, stem (see hypocotyl), and root (see radicle), as well as one or more cotyledons. Once the embryo begins to germinate grow out from the seed it is called a seedling. .....

Once placed in water, the cyst-like embryos hatch within a few hours, and will grow to a length of around one centimeter on average.

This short life span, and other characteristics, such as their ability to remain dormant for long periods have made them invaluable in scientific research, including space experiments Space exploration is the physical exploration of outer-earth objects and generally anything that involves the technologies, science, and politics regarding space endeavors. The idea of sending an object to space was conceived in the minds of many science fiction authors hundreds of years before it was actually feasible. Some of these works even included various descriptions of exactly how that would be done. During the 20th century, with the development of adequate propulsion technologies, stronger and lighter materials and other technological and scientific breakthroughs, the idea of outer-earth missions was no longer a dream, but a viable practice. .....

DefinitionsWater is defined as saline if it contains 3 to 5% salt by volume. The ocean is naturally saline at approximately 3.5% salt (see sea water). Some inland salt lakes (seas) are even saltier. The technical term for ocean saltiness is halinity, from the fact that halides (chloride, specifically) are the most abundant anion in the mix of dissolved solids. In oceanography, it has been traditional to express salinity as concentration in parts per thousand (ppt or °), which is grams salt per liter of water. After 1978, oceanographers defined salinity as the electrical conductivity ratio of a sea water to a standard KCl solution. Ratios have no units. .....

Do not assume that they are safe! Most will have some sort of safety advice on the page but the absence of written precautions does not mean that you can just plough ahead. If you are an adult, you should use your own judgement. If you are under 18, you should ask the advice of your teachers or parents. .....

The nutritional properties of newly hatched brine shrimp make them particularly suitable to be sold as aquarium An aquarium is a glass-sided container (terrarium) in which water-dwelling plants and animals (usually fish) are kept in captivity. The term is also used of a public establishment that maintains a large number of aquatic species in captivity, much as a zoo does for land animals.

There are three forms of lipids: phospholipids, steroids. and triglycerides. Lipids consist of a polar or hydrophilic (attracted to water) head and one to three nonpolar or hydrophobic (repelled by water) tails (Fig. 1). Since lipids have both functions, they are called amphiphilic. The hydrophobic tail consists of one or two (in triglycerides, three) fatty acids. These are unbranched chains of carbon atoms (with the correct number of H atoms), which are connected by single bonds alone (saturated fatty acids) or by both single and double bonds (unsaturated fatty acids). The chains are usually 14-24 carbon groups long. .....

In color theory, saturation refers to the intensity of a specific hue. Saturation is also a coordinate in the HSV color space. See also: hue. An atmospheric humidity of 100% represents the saturation point, at which the air can hold no more moisture. see also Dew point In economics, there is the concept of market saturation. For magnetic materials, saturation is the state when the material cannot absorb a stronger magnetic field, such that an increase in magnetization does not produce significant change in magnetic flux density. In telecommunications, the term saturation has a number of meanings. .....

Most of the natural fatty acids have an even number of carbon atoms, because they are made up of acetate which has two carbon atoms. Industrially, fatty acids are produced by the hydrolysis of the ester linkages in a fat or biological oil (both of which are triglycerides), with the removal of glycerol. See oleochemicals. .....

These nutritional benefits are likely to be one reason that brine shrimp are found only in highly salinated waters, as these areas are uninhabitable for potential predators.
