Estuary By: Calvin Marsh
QueEs? • An estuary is where fresh water and salt water meet • The farther you get from the ocean the more fresh water, the farther you are from the river the more salt water • Fish that live in the estuary can not just go from the freshwater into the ocean or visa versa( execpt for a special for) (Ex. Salmon) • A good way to describe a estuary is a delta with brackish water (mixture of fresh and salt)
Animals • All kinds of animals live in a estuary • There are a lot of oyster fields • Tons of aquatic life in an estuary • Trout • Clown fish • Blue and mud crabs • Seahorses • More near the ocean end of the estuary you can find • Dolphins • Sharks • Rays • Sea turtles
Vegetation • Many vegetation would have trouble growing in such an environment, but some flourish • Sea rush grows on the edge of the water ways • Salt meadows also flourish on the edge of the water (looks like hay) • Sea grass is the only submerged flowering vegetation in a estuary ( like sea weed) • Mangrove trees dominate the water with their huge elevating roots
Climate • The climate of an estuary does vary • In a warmer area of the world the climate will most likely be humid and warm • In a colder area the climate may be cold with frozen parts of the water ways
Human Interaction • The human interaction in estuaries is slim • One of the main things is poaching • Gators live in estuaries and poachers like to kill them and skin them to make a quick buck • We also have sewer lines and other water lines that lead eventually lead into the water ways • These can harm the animals that live there as well as our water purity • One thing you might not think about is that an estuary is fed by both rivers and the ocean so what happens out there can lead back to an estuary
Those Pesky Varmint! • Animals that live in an estuary just follow the circle of life • If they eat plants they eat the plants • If they eat other animals poop they do that • If they eat other animals heck they do that (we catching the drift now?)
