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.
