1 The Benthic Zone Chapter 7 Oceans

2 What adaptations have organisms made to survive in the deepest, darkest parts of the ocean?

3 Adaptations Extremely high pressure No sunlight
Bioluminescence- create light through a chemical process (i.e. firefly in PA) Large teeth, skulls, & stomachs

4 Fangtooth Fish

5 Why do you think bioluminescence occurs?

6 Light Fish

7 Bioluminescence Find food Attract prey Defend against predators
Communication Find mates

8 How does it work? Luciferase enzyme reacts with the chemical luciferin
3rd element present (depending on organism (i.e. ATP, calcium, etc) Luciferin + Luciferase + Oxygen + Salt  Light + Water

9 Angler Fish

10 Other Adaptations Pressure- 3000-9000 pounds/square inch! No sunlight
Large teeth, skulls, & stomachs- scientists are still unsure of why organisms have these characteristics

11 Giant Squid

12 Dragon Fish

13 Gulper Eel

14 Giant Isopod

15 Long-nosed chimaera

16 Explain different adaptations organisms made to survive in the deepest, darkest parts of the ocean.
