Key Questions:1. What is the benthic environment?2. What is the interdial zone?3. What is the sublittoral zone?4. What is the bathyal zone?5. What is the abyssal zone?6. What is the Hadal zone?7. What is the neritic zone?8. What is the oceanic zone?
Benthic Environment-the ocean floor and the organisms that live in or on it
Benthic > Intertidal ZoneShallowest zoneLocated between high and low tideCovered by water (low tide) and
exposed to air and sun (high tide)Clams, oysters, crabs
Benthic > SublittoralStarts where intertidal ends and edge of continental shelf
Stable temperature, water pressure, sunlight
Corals
Benthic > BathyalOn continental slopeLittle sunlight or plantsSponge, sea stars, octopus
Benthic > Abyssal On abyssal plainNo sunlightNo plantsFew animalsSea cucumbers, crabs,
sponges, worms
Benthic > HadalLocated in Trenches
Deepest zoneNo sunlight or plants
Few AnimalsFloor of trenchesSponge, worms, clams
Pelagic > Neritic ZoneWarmShallow (Over the
Continental Shelf)Largest
concentration of marine life
Fish, plankton, marine animals
Pelagic > Oceanic ZoneWhole ocean floor except
the continental shelfDeeper, Colder, More
PressureAngler fish
