2Types of Organisms Organisms classified based on: Three types: How they moveWhere they liveThree types:BenthosPlanktonNekton
3Benthos Live on or near bottom of ocean Snails, StarfishSometimes attached to ocean floorKelp Forests, Sponges
4Plankton Tiny organisms that move due to currents. Zooplankton- animal like. Example: KrillPhytoplankton- plant-like. Example-algae and diatoms.
5Nekton Free-swimming Found in all layers of ocean Examples: Fish, Whales, Eels, Seals, etc.
6Oceanic Zones Three different zones based on distance from shoreline. IntertidalNeriticOceanicEach house different organisms! **1**
7Intertidal Description: Shoreline area between high and low tide mark. Organisms: sea anemones, starfish, crabs, seaweed, barnacles, birdsAdaptations: Need to be to survive at high tide and low tide. Be able to hang on and not get washed away by the waves.Characteristics of the water: Shallow.
9Neritic ZoneDescription: gentle slope from the shore to the deeper ocean floor.Organisms: coral reefs, kelp forests, fish, algae, starfish, eels, clownfish, sea anemones, turtlesAdaptations: Home to most life in the oceans.Characteristics: Fairly constant temperature, sunlight, and salinity. Ocean depth up to 200 feet.
11Neretic Zone (coral reefs and kelp forests) First daynemo
12Oceanic Zone Description: Deep open waters. Hydrothermal vents Organisms: whales, dolphins, sharks, squid, jellyfish, krill.Adaptations: Most live in top 200 meters of the surface.Characteristics: Sunlight only in the top 200 meters. High pressure and low temperatures below 200 meters. No sunlight and dark below 200 meters.
