Intertidal Zone The intertidal zone is a very harsh environment. The organisms that live here have adaptions that allow them to live both submerged with water and out of water. Depth: From High tide down to low tide. Sea anemones Starfish Clams Oysters Barnacles Crabs seaweed

Sublittoral Zone The sublittoral zone is a stable environment. The temperature, water pressure, and amount of sunlight remain fairly constant. Depth: Low tide to the end of the continental shelf (about 200m below sea level) Corals Reef fishes Crabs Lobsters

Bathyal Zone The bathyal zone is void of sunlight and there are very little plants found here. (WHY??) Depth: 200m to 4,000m below sea level. Sponges, brachiopods, sea stars, echinoids, and octopuses.

Abyssal Zone The Abyssal zone contains very few plants and animals. This zone is located on the abyssal plain which can reach 4,000m in depth. Depth: A plain that ranges from 4,000m to 6,000m. Crabs Sponges Worms Sea cucumbers

Hadal Zone This is the deepest zone and consists of the floor of the ocean trenches and all the organisms that live there. Scientists know very little about this zone! Depth: 6,000m to 7,000m So far scientists have only discovered: A few species of worms A sponge A clam

Neritic Zone The Neritic zone covers the continental shelf. It is a warm, shallow zone that receives the most sunlight of all the zones. It also contains the largest concentration of marine life. Depth: 0m to 200m of “Open water” Marine mammals Dolphins Fish Plankton

Oceanic Zone The oceanic zone contains the volume of water that convers the entire sea floor except for the continental shelf. It varies in temperature and sunlight based on the depth. Some of the organisms found in the neritic zone are found in the upper oceanic zone. Depth: 200m – 6,000m Giant squid Angler fish Whale species
