 The oceanic zone extends from 200m deep all the way down to the ocean floor. This could be thousands of feet. The organisms in this zone are benthos.

 The photic zone is the depth of water in a lake or ocean, that is exposed to efficient sunlight occurs. The depths of this zone can be greatly affected by seasonal turbidity. The organisms in this zone are called Phytoplankton.

 This is the portion of the lake or ocean where there is little or no sunlight. Bioluminescence is essentially the only light found in this zone. This zone underlies the photic zone. Animals like angelfish, squid and jellyfish live in this zone.

 the part of the ocean extending from the low tide mark to the edge of the continental shelf It is a relatively shallow depth of about 200 meters. This zone has generally well oxygenated water, low water pressure and relatively stable temperature.

The extended perimeter of each continent and associated costal plains, and was part of the continent during the glacial periods.

 Aragonite structures produced by living organisms. In most reefs the predominate organism are colonial cnidarians that secrete an exoskeleton of calcium carbonate.

 A semi enclosed costal body of water with one or more rivers or streams flowing into it and with a free connection to the open sea. They are often the tidal mouths of rivers.

 The area that is exposed to the air at low tide and submerged at high tide. Water is available regularly with the tides but varies from fresh with rain to highly saline and dry salt water.

 An area of land whose soil is saturated with moisture either permanently or seasonally. Such areas may also be covered partially or completely by shallow pools of water.

 A type of marsh that is a transitional intertidal between land and salty brackish water. They are one of the most biologically productive habitats on the planet.

 Trees and shrubs that grow in brackish coastal habitats in the tropics and subtropics.
