(Seacoast) between low tide mark at the shore and the start of the continental shelf.

 No light penetrates in the zone; no green plants or phytoplankton (they need sunlight for photosynthesis!). (anglerfish, tubeworms, giant squid)

Most animals depend on their senses since there is no light.

Some animals create their own light through bioluminescence. They can attract or even warn other animals! 

Abyssal zone – extends to the ocean

• Aphotic

• Photic

• Abyssal

• Littoral

• Intertidal

Extends to the ocean floor plane (fish, worms, squid, octopuses)

This zone is cold and dark!

Marine snow is a gentle shower of organic matter (partly dead animals) that these animals use for food.

Surprisingly, many of these fish tend to live longer!
