Are dolphins in the abyssal zone?
Beyond the shore and reefs, this zone is characterized by a mixing of cold and warm ocean currents. Whales and dolphins make their home here, and feed on the tons of plankton native to this area. The abyssal zone is one of the most eerie biomes of the ocean.
Do dolphins live in the Epipelagic zone?
The epipelagic is home to all sorts of iconic animals, like whales and dolphins, billfishes, tunas, jellyfishes, sharks, and many other groups. It is more commonly known as the sunlight zone because this is where most visible light exists.
What animals live in the disphotic zone?
Examples of disphotic zone animals include algae, coelacanths, copepods, crabs and other crustaceans, ctenophores, dinoflagellates, dragonfish, fangtooth, gulper eel, hatchet fish, hydrozoans, medusas, lantern fish, snipe eels, some octopuses, mid-water jellyfish (Cnidarians), plankton, polychaetes, radiolarians.
Do dolphins live in the euphotic 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 habitat do dolphins live?
They inhabit a wide variety of habitats, including harbors, bays, gulfs, and estuaries, as well as nearshore coastal waters, deeper waters over the continental shelf, and even far offshore in the open ocean.
Why is the Epipelagic zone important?
Algae that live in the epipelagic zone are responsible for much of the original food production for the entire ocean and create at least 50% of the oxygen in the atmosphere (both through photosynthesis). Organisms that live in the epipelagic zone may come into contact with the sea surface.
What ocean do dolphins live in?
Dolphins live in all oceans of the planet and even in some important rivers. While not all species of dolphins live everywhere, there is a species for each environment. Specifically one of the best-known species, the bottlenose dolphin lives in every ocean of the world except the Arctic and the Antarctic oceans.
Where is the disphotic zone?
The disphotic zone is the layer below the euphotic zone. This layer is also known as the twilight zone. In this zone, there is enough light for visual predators to see, and even for some photosynthesis. Howver, the rate of respiration in the disphotic zone is greater than the rate of photosynthesis.
What is the difference between the Euphotic and the Disphotic zones?
The euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.
Which zone does a dolphin live in?
Bottlenose dolphins are found in temperate and tropical waters around the world. They inhabit a wide variety of habitats, including harbors, bays, gulfs, and estuaries, as well as nearshore coastal waters, deeper waters over the continental shelf, and even far offshore in the open ocean.
How big is the disphotic zone in the ocean?
It is usually begins somewhere between these two extremes. The disphotic zone extends to about 3,300 feet (about 1,000 m) deep (this is where the aphotic zone begins). On average, this zone extends from 660 to 3,300 feet (200 to 1,000 m).
How many species of dolphins are there in the world?
There are currently 42 species of dolphins and seven species of porpoises. Dolphins are marine mammals. They must surface to breathe air and give birth to live young. A dolphin pregnancy last between nine and 16 months.
Where are bottlenose dolphins found in the world?
There are 36 species of marine dolphins – living in nearly all aquatic environments, including oceans, coastal, estuarine and freshwater – and in temperatures ranging from less than 0°C to more than 30°C. In Britain, bottlenose dolphins are concentrated around west Wales and eastern Scotland – with the coasts of Devon and Cornwall also having pods.
What kind of animals live in the disphotic zone?
Examples of disphotic zone animals include algae, coelacanths, copepods, crabs and other crustaceans, ctenophores, dinoflagellates, dragonfish, fangtooth, gulper eel, hatchet fish, hydrozoans, medusas, lantern fish, snipe eels, some octopuses, mid-water jellyfish (Cnidarians), plankton, polychaetes, radiolarians, siphonophore, rattalk fish, sea
