1. The division between the epipelagic and mesopelagic zones.
The epipelagic zone is the area most generally known to humans where most marine mammals live and many go scuba diving. Most sunlight penetrates here. The mesopelagic zone is known as the twilight zone and gets darker as depth increases. Nutrients are limited here; many animals have large teeth to capture prey. The presence of less light is the reason for the division causing the animals in the mesopelagic zone to adapt. The Mesopelagic zone doesn’t get enough light for photosynthesis and there is lower dissolved oxygen levels.
2. The division between the mesopelagic and bathypelagic zones. This boundary is about 1000 meters deep, and it is a level at which many physical and chemical changes occur. …show more content…
The bathypelagic zone doesn’t get any light. The animals most commonly found are fish, mollusks, crustaceans, and jellyfish. Red and black are the predominant colors of animals that live here and any bioluminescence is usually blue since red isn’t visible at these depths.
3. The division between the supralittoral (above high tide) and littoral zones.
The Supralittoral zone outlines the stretch above the high water level; seawater penetrates the elevated areas only during storms with highest tides. Organisms the live here cope with long periods of exposure to air as well as heat, cold, rain (fresh water), and predation by land animals and seabirds. The littoral zone is the closest to the shore and below water. The division between these is because the supralittoral zone is above high water and the littoral is
