The Sunlit Zone
What lives in the photic zone?
Ninety percent of marine life
lives in the photic zone, which is approximately two hundred meters deep. This includes phytoplankton (plants), including dinoflagellates, diatoms, cyanobacteria, coccolithophorids, and cryptomonads. It also includes zooplankton, the consumers in the photic zone.
Do whales live in the photic zone?
Whales eat at depths of total darkness. When they need air, they rise to the surface and bring the phytoplankton with them.
The surface water receives sunlight
and is called the photic zone. … Then, as if they hadn’t already done enough, whales release fecal plumes (poo) throughout the ocean’s surface.
What ocean zone does a seahorse live in?
Habitat. Seahorses are mainly found in
shallow tropical and temperate salt water
throughout the world, from about 45°S to 45°N. They live in sheltered areas such as seagrass beds, estuaries, coral reefs, and mangroves. Four species are found in Pacific waters from North America to South America.
What photic zone does plankton live?
Photic zone, surface layer of the ocean that receives sunlight. The uppermost 80 m (260 feet) or more of the ocean, which is sufficiently illuminated to permit photosynthesis by phytoplankton and plants, is called
the euphotic zone
.
What are the 3 zones of the ocean?
There are three main ocean zones based on distance from shore. They are
the intertidal zone, neritic
What ocean zone has sharks?
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. This extreme environment is limited in both sunlight and food.
Do seahorses eat their babies?
The seahorse father does not eat until several hours after he has given birth. However, if the babies are still hanging around him after that, they may become a tasty meal. That’s right,

At what depth does light no longer reach the ocean?
Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light
beyond 200 meters
. The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.
How deep is a photic zone?
Photic zone, the top few meters into which light penetrates and photosynthesis is possible; 2. Remainder of the surface or mixed layer, extending to
about 100 m depth
, in which temperature, composition, and nutrient levels are somewhat variable and convective mixing occurs; 3.
How deep is the sunlight zone?
This surface layer is also called the sunlight zone and extends from
the surface to 200 meters (660 feet)
. It is in this zone that most of the visible light exists. With the light comes heating from sun.
Which ocean zone is the warmest?
The epipelagic
What fish live in the abyssal zone?
