They contain saltwater and freshwater
They contain elements of both freshwater and saltwater ecosystems.
Only animals that can live in freshwater or saltwater live in an estuary because estuaries are places where freshwater and saltwater meet.
Gulfs can contain either freshwater or saltwater, but most are primarily saltwater bodies connected to oceans. For example, the Gulf of Mexico is a saltwater body, while some smaller coastal areas or estuaries may have a mix of saltwater and freshwater. Freshwater influx from rivers and streams can create brackish conditions in certain parts of a gulf, but the overall classification usually leans towards saltwater.
In all of the world's oceans. Some can even live in estuaries (where the freshwater from rivers or streams connect with the saltwater from sea).
Estuaries
they are both saltwater and freshwater
The Persian Gulf is saltwater, not freshwater.
An area where fresh river water mingles with tidal sea water is termed 'brackish'. Examples are: estuaries and mangrove swamps.
Saltwater is heavier because saltwater contains salt which adds to its overall weight. Freshwater does not have any dissolved salt so it is lighter then saltwater
The place where saltwater and freshwater meet is called an estuary. Estuaries are typically found at the mouths of rivers, where freshwater from rivers mixes with saltwater from the ocean. This unique environment supports diverse ecosystems and provides critical habitats for various species of fish and wildlife.
Shrimps grow in both saltwater and freshwater environments. They can be found in coastal waters, estuaries, and even some freshwater lakes and rivers. Shrimps usually live on the ocean floor, hiding in crevices or burrowing in the sand.
