Characteristics and Adaptations

The Ocean Depths The ocean depths include a number of distinct habitats: – Epipelagic zone - upper 200 meters; the photic zone – Mesopelagic zone – m.

The ocean changes as you descend into it. It becomes colder, darker, home to fewer living things. Scientists consider the ocean as being made up of five.

Zones of the Ocean. It’s all just one big ocean!

Marine Ecosystem: The Oceans

Biological Oceanography:

How many layers do you think the ocean has? The ocean has exactly 5 layers!

COASTAL ZONES Ocean Zones. there are several different ocean zones that are determined by: – light – depth – bottom divisions.

Midwater/Deep Ocean

What is the Midwater? Aka the Twilight world Mesopelagic Zone Upper part has dim light during the day 200 m to about 1,00 m deep in the ocean is the mid ocean Temperature ranges drastically (~2 ºC to 22 ºC)

Adaptations of Midwater Animals Food is not abundant so the fish are quite small Large mouths Broad diets Tubular eyes Countershading/Transparency Photophores Bioluminescence Advanced gills

Typical Midwater Fish

What is the deep sea? Depths below 1,000 m (3,280 ft or 0.6 mi) NO light – Completely dark Super cold 1 to 2 ºC (35 ºF) Very little food

Adaptations of Deep Sea Animals Sluggish Weak Skeletons No Scales Poor Muscles No Swim Bladder Hermaphrodites/Male Parasitism
