The two types of aquatic life zones on the Earth are freshwater life zones and coastal life zones.

Aquatic Life Zones

Specific areas in bodies of water, categorized by depth, light penetration, temperature, and other factors, that support various forms of life, including freshwater and marine ecosystems.

Coastal Life Zones

Areas along the coast characterized by distinct biological communities and abiotic conditions, often defined by factors such as depth, salinity, and wave action.
