  1. Marine Biome Rachel Speaker Alison Lunden

  2. Description • The Marine Biome have many features. • It is broken up into zones going away from the coast and layers going from top to bottom. • It is made up of Oceans, Coral Reefs, and Estuaries. • The Marine Biome is all salt water.

  3. Zones & Layers zones Layers • Intertidal Zone • Pelagic Zone • Abyssal Zone

  4. The intertidal zone • This is where the ocean meets the land. • Sometimes it is under water and sometimes it is not • The waves and tides affect it. • Communities are constantly changing • Where the highest tides reach, there are only a few species of algae and mollusks • Herbivorous snails, crabs, sea stars, and small fishes live here when the tide is high and land is submerged. • Invertebrates, fishes, and seaweed live in the lowest part of this region where the land is only showing when the lowest tide occurs. • Waves keep sand and mud moving all the time • 2 high tides and 2 low tides each day • Any organisms living there must be able to withstand these constant changes, and pounding of water

  5. Life in the Intertidal Zone • This is where the coral Reefs are. • Corals live here and they survive using photosynthesis. • Algae is also another plant that lives here. • Starfish, octopi, and mollusks are a few other organisms that call this place home.

  6. Pelagic Zone • This includes the waters further from the land, basically the open ocean. • Generally cold, but it is hard to tell an exact temperature because the water is constantly being mixed with warm and cold currents. • Plants are surface seaweed • All sorts of bacteria, fungi, sponges, sea anemones, worms, sea stars, and fishes

  7. Life in the Pelagic Zone • Many organisms call this place home. • There are few plants though. • It is mostly fish, mammals, plankton, starfish, anemones, sponges, microorganisms, and floating seaweed.

  8. Abyssal Zone • This is the deep ocean. • Very cold (around 3° C) • Very dark because the sun doesn’t reach this zone. • Highly pressured, high in oxygen content, but low in nutritional content • Many species of invertebrates and fishes • Mid-ocean ridges are found here. • Trenches, vents, and volcanoes on the tectonic plates.

  9. Life in the Abyssal Zone • Fish that glow in the dark generally live here. • A Fish called Coelacanth is a prehistoric fish that was thought to be extinct that was found again at the bottom of the Indian Ocean.
