July 2023 · 6 minute read

These are the fishes, marine mammals, worms, sponges, molluscs, sea stars and reptiles. While some of these large animals feed on fish, others, such as the baleen whale, feed on plankton.

What is in the sunlight zone? The upper 200 meters of the ocean is called the euphotic, or “sunlight,” zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles. Only a small amount of light penetrates beyond this depth.

also,  Do sharks live in the photic 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.

Why do animals live in the photic zone? Most marine life is concentrated in coastal areas and in the upper layers of the oceans where, thanks to the entry of sunlight, plants can perform photosynthesis, thereby generating the vital support for the base of the chain food. These brighter marine sites are known as photic zone.

What is the temperature of the photic zone?

What is the temperature of the photic zone? 104 to 27 degrees F. On average, it extends to about 660 feet (200 meters); the depth of the ocean averages about 13,000 feet or 4,000 m.

similary What are the two photic layer zones?

Sunlight only penetrates the sea surface to a depth of about 200 m, creating the photic zone (consisting of the Sunlight Zone and Twilight Zone).

What makes the sunlight zone so important? From Sunlight to Darkness

The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.

Do crabs live in the sunlight zone? Sunlight penetrates to a very little extent, which makes the process of photosynthesis impossible. Supported Plant Species: No plants exist in this zone due to lack of light. Supported Animal Species: Squid, crab, cuttlefish, lancetfish, chain catshark, swordfish, wolf eels, bigeye tuna, calm, gastropods, krill.

Do swordfish live in the sunlight zone?

Sea turtles and stingrays also live in this layer. Just below the sunlight zone is the twilight zone. This zone still gets some sunlight, but is colder. … Examples of twilight zone animals include cuttlefish, swordfish, and wolf eels.

What fish live in the twilight zone? Animals that live in the twilight zone include: lantern fish, rattalk fish, hatchet fish, viperfish, and mid-water jellyfish. This murky part of the ocean begins at about 600 feet under the water and extends to the darkest part, which begins about 3000 feet down. Some squid and fish can use their bodies to make light.

How do animals adapt to the photic zone?

In the well-lit (photic) or epipelagic-zone, most predators use vision to seek out prey. There are several adaptations that allow prey organisms to survive here. One adaptation is small size. The most numerous organisms of the well-lit zone, the zooplankton, are small.

Do dolphins live in the photic zone? Bottlenose Dolphins live in the pelagic zone of the ocean, which includes those waters further from the land, basically the open ocean. The pelagic zone is generally cold.

What happens in a photic part of a body of water apex?

The word photic means referring to light. This the zone of a body of water that light can penetrate and photosynthesis can still occur. It usually starts at the surface and goes to a depth that is about 1% of the light intensity that is found at the surface.

Does the blue whale live in the sunlight zone?

Sunlight is the energy that powers all life in the upper level of the ocean. … As a result, this is the open sea zone where most life exists. Blue whales, the largest animals to ever live, cruise slowly through the Sunlit Zone, eating as much as 8,000 lbs (3,628 kg) of tiny krill per day.

Is the photic zone in the pelagic zone? Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone.

What are the 3 main zones of the ocean? The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.

What are the 5 major zones in the ocean?

The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …

What is a fun fact about the sunlight zone? Sunlit Zone

This zone goes down to about 660 feet deep and is the zone that scuba divers explore, although even they need special diving equipment if they want to dive too deep. Because there is so much sunlight in this zone, this is where most sea animals live.

What is the pressure in the sunlight zone?

The pressure in the sunlight zone varies from one atmosphere of pressure at the surface up to about 21 atmospheres of pressure at the bottom of the sunlight zone, about 200 metres below the surface. The quantity of pressure in the ocean increases by about one atmosphere for every 10 meters of depth.

What type of sharks live in the sunlight zone? Most of the time, great white sharks live in the sunshine zone, or Epipelagic zone. This is the topmost of the ocean zones.

What sharks live in the sunlight zone?

Predators such as hammerheads and silky sharks patrol these areas. The epipelagic or sunlight zone is teeming with life. But just a few hundred meters below lies a very different world.

What zone do octopus live in? The midnight zone is home to many different animals including the: Anglerfish, Octopuses, Vampire Squids, Eels, and Jellyfish. It is the third layer down from the top of the ocean. It is mostly dark and very cold in the midnight zone, just like the Abyssal zone we learned about yesterday.

What zone do anglerfish live in?

The deep sea anglerfish, also known as the humpback anglerfish, is a medium sized (7 inches/18 cm) anglerfish that lives in the bathypelagic zone of the open ocean. Living at depths of at least 6600 feet (2000 m), this species lives its life in the complete absence of sunlight.
