1 Ocean Environments

2 1.Benthic Zone – bottom 2.Pelagic Zone - water Two Basic Divisions

3 Benthic Zones 1. Intertidal –Shallowest area –Between the low and high tide lines –Changing environment

4 Periwinkle

5 Fingernail Limpet

6 Buckshot Barnacles Barnacle mating

7 Gooseneck Barnacles

8 Mussel with barnacles on it Mussels Mussel with barnacles on it

9 Sea star Sea Urchin Chiton Seaweed Sea anemones – closed above water, open below water

10 Benthic Zones 2. Sublittoral –Always underwater –On continental shelf –Most variety of benthic life

11 Coral Sponge with brittle star

12 Benthic Zones 3.Bathyal - starts at continental slope and extends to 4000 m - little or no sunlight - cold 4°C - very high pressure Brittle Stars

13 Crinoids (Sea Lilies)

14 Sea cucumbers

15 Benthic Zones 4.Abyssal - No sunlight - 4000 – 6000 m - On abyssal plain Tube worms

16 Benthic Zones 5.Hadal 6000m -11,000m Trench Foraminifera

17 Pelagic Zone – water area 1.Neritic  water area above continental shelf 2. Oceanic  water off of continental shelf  further divided into 5 areas based on depth

18 Oceanic zone is further divided into 5 areas based on depth

19 Neritic Zone Life Herring Angel fishClown fish Bluefin Tuna Seahorse Jellyfish

20 Plankton

21 Oceanic Zones 1.Epipelagic Surface – 200 meters Sunlight, warm

22 Oceanic Zones 2.Mesopelagic twilight zone - some light but no photosynthesis 200 – 2000 meters contains thermocline (large temperature change) low-energy tissues and sluggish lifestyles to cope with low food energy, since no algae can grow. Many animals are bioluminescent Firefly Squid Cuttlefish

23 Coelacanth Deep Sea Angler Ogrefish

24 Giant Siphonophore

25 Bloodbelly Comb Jelly

26 Pelagic Zones 3.Bathypelagic zone 2,000 – 4,000 meters Vampire Squid Giant Squid

27 Pelagic Zones 4.Abyssopelagic zone - 4000 – 6000 meters -low oxygen, nutrients and food -Dark and cold Snipe Eel Zoarcid Fish
