Estuaries
Smal ones..
In shallow, slow moving rivers, estuaries, saltwater bays, canals and costal areas
Estuaries are important nurseries for many species of fish, crustaceans, and shellfish. These organisms rely on the shallow, nutrient-rich waters of estuaries for protection from predators, access to food, and optimal conditions for growth and development before moving to deeper waters as adults.
The common snapping turtle is a freshwater species of amphibian. Typically, these turtles dwell in areas like shallow ponds, shallow lakes, streams and rarely estuaries.
Seahorses can be found in shallow tropical and temperate waters around the world. They shelter in sea grass beds, coral reefs, estuaries, or mangroves.
What is happening to estuaries?
The three types of estuaries are coastal plain estuaries, bar-built estuaries, and tectonic estuaries. Coastal plain estuaries form when sea levels rise, flooding existing river valleys. Bar-built estuaries are separated from the ocean by sandbars or barrier islands. Tectonic estuaries result from land movement, such as faults or folding, creating a depression that fills with water.

Tides in estuaries create a dynamic environment where the mixing of saltwater and freshwater influences the distribution of nutrients, sediments, and organisms. The rise and fall of tides can help flush out pollutants and bring in nutrients, supporting diverse ecosystems in estuaries. High tides bring in saltwater, while low tides allow for the accumulation of organic matter and sediment.
Estuaries are the most productive of all marine ecosystems.
An estuary is a shallow, enclosed area, connected to the sea, that forms at the mouth of one or more rivers, where freshwater and seawater mix. There are approximately 300 estuaries around the coast of New Zealand.
