What lives in the littoral zone?

What lives in the littoral zone?

Organisms in this area include anemones, barnacles, chitons, crabs, green algae, isopods, limpets, mussels, sea lettuce, sea palms, sea stars, snails, sponges, and whelks. Low Tide Zone: Also called the Lower Littoral Zone. This area is usually under water - it is only exposed when the tide is unusually low.

What is the Disphotic layer?

The disphotic zone, also known as the twilight zone, is the layer of water with enough light for predators to see but not enough for the rate of photosynthesis to be greater than the rate of respiration. The depth at which less than one percent of sunlight reaches begins the aphotic zone.

Do sharks live in the Twilight Zone?

Habitat. Deep sea sharks live below the photic zone of the ocean, primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. ... The sharks in this zone feed primarily on other deep-sea creatures.

Why is sea water blue?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Which pelagic zone is the deepest?

This is also known as the abyssal zone. Hadopelagic zone (deep ocean trenches, greater than 6,000m) - In some places, there are trenches that are deeper than the surrounding ocean floor. These areas are the hadopelagic zone. At a depth of over 36,000 feet, the Mariana Trench is the deepest known point in the ocean.

Are sharks pelagic?

Pelagic or oceanic sharks live in the open waters of seas and oceans. They inhabit tropical and temperate waters, and many are migratory. Pelagic sharks are constantly on the move, and rely on lift from their pectoral fins and buoyancy from the low density oils in their large livers to stop them from sinking.
