An estuary is a stretch of water that is created out of fresh water from rivers and it mixes with salt water which comes from the ocean. In an estuary the fresh water is blocked from going into the ocean by mainland and salt marshes. But the mixes of salt and fresh waters make an amazing environment that has all different types of animals and plants of all kind.
There are many types of animals that live in an estuary. But there is a select few that I will talk about.
Found in southern Europe & the US the great egret is a big heron with a white body, black feet, and very long legs. It also has a yellow bill. A very interesting characteristic about this animal is that it has a long neck that is made into a shaped curve while it’s flying.
Around the Chesapeake Bay Hermit crabs live in estuaries. The shell of a hermit crab is a very protective armor because it is beneficial for survival and protection. Hermit crabs are able to live in salt water or freshwater.
A lugworm is another species that lives in an estuary. A lugworm is found in Europe and can be between 3 to 12 inches and3/8 inches in diameter. It looks like a large earthworm. Its head is blackish reddish

and the middle part is flat and red. Then it gets thinner and is yellowish red at the tail. In the middle it has bristles on both sides and has pairs if feathery gills. The lugworm has a well developed system of blood vessels with red blood rich in the oxygen carrying a pigment called hemoglobin. The most fascinating animal in an estuary to me is the starry flounder and is mostly found in Japan and Korea. It is not very large but, its shape and color pattern makes it interesting. It also can lay between 900,000 thru 11,000,000 eggs. Wow that is interesting. They mainly are meant to be kept in an aquarium The plants that are found in estuaries are very interesting in their own way. It is a hostile environment for plants to live in a estuary because the salt dominates. A few grow closer to the shore where there is a mixture of sea water and fresh water. The smooth cord grass is the most common form of marsh vegetation and is a very vital plant in the estuary. Only a small amount of smooth cord grass is seen extending from the high peak of the marsh to the water. It is very important to the marsh health because of the high volume of organic material it has during decomposition. Smooth cord grass can be between 6 inches and 7 feet tall. It grows taller when closer to water. The shorter parts are found around the low elevation in the marsh. It is found in America and Canada. Spike grass is a short grass that grows near or around the marshland.
It is the most common type of grass on the shorelines of estuaries. While growing up it will stand tall and have one budding flower at the top. It can handle salty environments. It is an ideal plant found in estuaries. The salt water also distributes salt particles around the marshland and shore land. The purple loosestrife is a hard plant which was found in Europe and came to America during the trade and exploration time. The plant has a rigid stalk with matted root ends. The way the roots are made it prevents the plant from growing tall. The top section of the plant is a hardy plant and lives in the marshland and near the shoreline. The purple loosestrife can live in tough environments and can easily take control and kill other
plants. This sort frames where an expansive waterway inputs heaps of new water in a zone where the tidal extent is low or direct . The leaving crisp water keeps down a wedge of meddling seawater. Since new water is less thick than salt water, the waterway water stays close to the top and streams offshore. The seawater wedge moves toward the ocean amid falling tides or times of solid waterway stream; it moves landward amid rising tides. Blending happens at the limit between the two water masses and can be particularly aggregated at the Straight's base, where new and salt water meet. This sort shapes where waterways information littler measures of crisp water and the tidal extent is moderate to high . While in the salt-wedge sort there is an in number saltiness angle from surface to base, in the all around blended sort saltiness is more consistent from surface to base. As in alternate sorts of estuaries, there is a toward the ocean saltiness inclination from fresher water landward to saltier water offshore. This sort shapes where streams information littler measures of new water and the tidal extent is moderate to high . Though in the salt-wedge sort there is an in number saltiness slope from surface to base, in the all around blended sort saltiness is more consistent from surface to base. As in alternate sorts of estuaries, there is an offshore saltiness angle from fresher water landward to saltier water toward the ocean. All around blended conditions have a tendency to happen in shallow estuaries, for example, the mouth of the Columbia River, where tidal streams can altogether blend waterway and ocean water. This sort is transitional between salt-wedge and very much blended sorts, and happens in more profound estuaries with tolerably solid tidal streams and more noteworthy measures of waterway inflow . Blending is driven both by tidal turbulence and stream. The saltiness angle is transitional between sorts an and Examples are the fundamental assortment of San Francisco Bay.

The Chesapeake and New England regions were settled by people of English descent, but by 1700, they had become two distinctly different societies. They had evolved so differently, mainly because of the way that the settlers followed their religion, their way of conducting politics and demographics in the colonies. Even though the settlers came from the same homeland: England, each group had its own reasons for coming to the New World and different ideas planned for the colonies.
The Crusades of the middle ages introduced much innovative and formerly unheard of merchandise into Western Europe; however the scarcity of these luxury goods instilled Europeans with drive to find easier access to the Far East. Although desired "Northwest Passage" never was found, joint-stock companies, like the Virginia Company of London, settled colonies in the New World for untapped resources such as silver and other tradable goods. Many more corporations followed suit, settling mainly in the Chesapeake Bay area, their small settlements eventually developing into the Chesapeake colonies. The Chesapeake colonies were focused primarily on profitable enterprises. At the same time, the New England colonies were being settled with a whole different set of initiatives, principally religious freedoms and family. Governing bodies were established, with their success dependent on the quality of the settlers the colony attracted. The different motives for settlement affected the routine events in such a way that the New England and Chesapeake colonies differed very greatly from one another even though they were both mainly settled by the English.
Looking at the early English colonies in the Chesapeake Bay region, it’s clear that the English had not learned any lessons from their experiences at Roanoke. Poor planning, a bad location, unrealistic expectations, flawed leadership, unsuccessful relations with the local Indians, and no hope of finding the mineral wealth the Spanish found in Mexico, all contributed to failure. The first colonists in the Chesapeake region were not only ignorant, lazy and unambitious, but their attempts were hampered before they had begun. However, a solution to these problems was found in a single plant: tobacco. Nevertheless, this cash crop ultimately created numerous problems for the colonists. The ignorance and indolent acts of the Chesapeake colonists to unsuccessfully restore the colony by themselves led to the demise of the colony as a whole especially regarding the planting of agricultural goods for food.
One of the two first colonies established in the new world was The Chesapeake Bay colonies which included Virginia, Maryland, New Jersey, and Pennsylvania. The second was the Massachusetts Bay colonies including what now is the present-day central New England, portions of the U.S. states of Massachusetts, Maine, New Hampshire, Rhode Island, and Connecticut. The colonies are very similar but also different in their own distinct ways. The differences gave the colonies identities. A big resemblance between the colonies is that both left to create a new life out of England. Both settlements represented a new time of independence and development of religion. Mutually both groups went through a lot of suffering and pain in the accomplishment of such
During the 1600's, many people in the American colonies led very many different lives, some better than others. While life was hard for some groups, other colonists were healthy and happy. Two groups that display such a difference are the colonists of New England and Chesapeake Bay. New Englanders enjoyed a much higher standard of living. This high standard of New England's was due to many factors, including a healthier environment, better family situation, and a high rate of reproduction.
During the 1700's, people in the American colonies lived in very distinctive societies. While some colonists led hard lives, others were healthy and prosperous. The two groups who showed these differences were the colonists of the New England and Chesapeake Bay areas. The differentiating characteristics among the Chesapeake and New England colonies developed due to economy, religion, and motives for colonial expansion. The colonists of the New England area possessed a very happy and healthy life. This high way of living was due in part to better farming, a healthier environment, and a high rate of production because of more factories. The colonists of the Chesapeake Bay region, on the other hand, led harder lives compared to that of the colonists of New England. The Chesapeake Bay had an unhealthy environment, bad eating diets, and intolerable labor.
The Chesapeake region and New England colonies greatly differed in their development of their two distinct societies. The Chesapeake region was a loosely fitted society with little connection with each plantation while the New England colonies had tightly knitted communities with a sort of town pride. The difference in unity and the reason for this difference best explain the significant disparity between the dissimilar societies.
Although New England and the Chesapeake region were both settled largely by the people of English origin, by 1700 the regions had evolved into two distinct societies. The reasons for this distinct development were mostly based on the type on people from England who chose to settle in the two areas, and on the manner in which the areas were settled.
They also look after the quality of coastal waters by watering down, sifting, and settling deposits, left-over nutrients and contaminants. They are highly productive ecosystems and provide habitats and act as nurseries for all manner of life.
The Chesapeake Bay is a large estuary located on the east coast of the United States. The bay is over 200 miles long and goes through Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia. The bay has much to offer the locals. Many locals have made a career out of harvesting the bay's sea food. The bay's harvest and many of its other attractions bring tourists and in turn revenue for the area. Oysters and blue crab are a big part of the culture in the bay area. However, these organisms are in danger and need help.
Moreover, like other estuaries, the Long Island Sound has an abundance of fish and other waterfowl that add to the natural balance of the island, as well as one of the most important economic factors (Tedesco). Like other estuaries around the world, the Sound provides breeding, feeding, nesting, and nursery areas for many species that will spend most of their adult lives in the oceans (Long Island Sound Study). Despite these similarities to other estuaries, the Long Island Sound is unique from anywhere else in the world. Unlike other estuaries, the Long Island Sound does not just have one connection to the sea but it has two. It has two major sources of fresh water flowing into the bay that empty into the ocean.
Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Some species are like plankton (drifting in seawater), some are living on the ocean floor and some particular species may live in still-water habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ponds, and puddles, damp moss, or phytotelmata of plants.

Of course, the great white average length is anywhere from twelve to sixteen feet long, but they are not restricted to those limitations.
