Open Ocean and Deep Sea
High light intensity
Temperature, oxygen, light decrease with depth
Epipelagic = surface to 200 meters (150 meters in Levinton) depth,
seaward of the shelf-slope break.
Mesopelagic = 2001000 m depth, s
Species Interactions II
1) predation - benefits one
species, negative effects
on second species
Examples of mutualism are
common on coral reefs
Many fishes & invertebrates
take refuge within sea
Responsible in part for the high species

and the circumpolar paradigm for Antarctic marine invertebrates
