They're the mouth of rivers,
where the water can be either salt or fresh depending on the tides.
Lots of things (plants and animal) live there
and the ancestors of ALL land animal lived there about a half billion years ago.
Note that there are animals and plants that live in the sea that never had anything to do with estuaries, and couldn't care less for their existence.
But many of the animals that you are familiar with (like birds) use estuaries as breeding grounds.

∙ 12y agothere are two different characteristicts that make them different. one is the tides, when the tides are high it is to much salt in the water because of the sea water that comes in. while the tides are low it contains saltwater but does not contain salt water as much.

What is the most polluted intertidal habitats?
estuaries
Why do estuaries support such an abundance?
Estuaries support such an abundance of life because they provide a unique mix of nutrients from freshwater and saltwater sources, creating a rich and diverse ecosystem. The sheltered nature of estuaries also creates habitats that are ideal for many species to breed, feed, and seek protection from predators. Additionally, estuaries act as nurseries for juvenile fish and other organisms, contributing to the high levels of biodiversity found in these ecosystems.
What are types of soil are found in estuaries?
rich and saturated with water
What do beaches rocky shores and estuaries all have in common?
they both have in common is they both are ocean margin habitats
What are estuaries plants?
The most widespread vegetation within estuaries are mangroves. Some examples of the mangroves that thrive in estuarine habitats are red mangroves, black mangroves, white mangroves, and salt marsh.
What are the four ocean margin habitats found along the continental shelf?
the four ocean habitats are beaches, rock shore areas, estuaries and coral reefs. I learned this in science class.
Where do fishes usually live?
Fish generally live in aquatic habitats like lakes, rivers, ponds, estuaries and the ocean.
Why are estuaries such rich habitats organisms?
A lot of animals we use live in estuaries, and we ship things through it too. But that can also be a bad thing since water from there is taken to another country, and those water molecules will be in a different area, they are not used to it so it will attack the other water molecules in the new place.
How do estuaries sustain biodiversity in oceans?
Estuaries sustain biodiversity by providing a range of various habitats for many species to survive in. Birds, mammals, fish etc, use estuaries to breed, live and feed in. It is helpful in the survival of oceanic creatures and creates a sustainable area for survival. For more information please refer to the related link.
Where the river enters another body of water like the ocean?
Places where freshwater rivers and streams flow into the ocean are called estuaries. They are interesting places to explore with a rich array of plants, fish, birds and animals.Places where freshwater rivers and streams flow into the ocean are called estuaries.

What are habitats where Gastropod mollusks can be found?
Tidal regions, deep waters of the ocean, estuaries, fresh water lakes, ponds, streams, and moist areas on land
Why are tropical rain forests such rich habitats for species of animals?
it is mostly the climate?
