Sunlit Ocean (Euphotic) Zone Animal Printouts. The uppermost layer of the world's oceans is bathed in sunlight during the daytime. This bright ocean layer is called the sunlit zone or the euphotic zone (euphotic means "well lit" in Greek) or the epipelagic zone (epipelagic means "upon the sea"). The depth of this zone depends on the clarity or murkiness of the water.
The epipelagic zone reaches from the surface of the ocean down to around 650 feet. This is the zone most exposed to light, and as such is host to the highest concentrations of the ocean's life. There are thousands of animals that roam this zone, including dolphins, most sharks, jellyfish, tuna and corals.
From 200 m (660 ft) down to around 1,000 m (3,300 ft) The most abundant organisms thriving into the mesopelagic zone are heterotrophic bacteria. Examples of animals that live here are swordfish, squid, Anarhichadidae or "wolffish" and some species of cuttlefish.Many organisms that live in this zone are bioluminescent. Some creatures living in the mesopelagic zone rise to the epipelagic z...
A unique quality that some of the animals in the epipelagic layer have is a type of camoflauge called countershading. This is where the animal is light on the bottom of their bodies and darker on the top. This allows the animal to blend in with the light when a predator is below or blend in with the water when a predator is on the top of the ...
The epipelagic zone is uppermost part of the oceanic zone to allow for photosynthesis. Animals and life in this region must adapt to lower levels of sunlight and reduced oxygen use.
The epipelagic zone The epipelagic zone (or the sunlight zone) is the only layer of the oceans where photosynthesis takes place. The importance of photosynthesis: photosynthesis is a process of sunlight and carbon dioxide gas converting into oxygen gas and food. Most of the oxygen is created by phytoplankton which are called autotrophs.
According to Encyclopedia Britannica, the pelagic zone, or open ocean, includes animals classified as either zooplankton or nekton. Zooplankton are small organisms that drift in the ocean currents and make up an enormous portion of the ocean's food supply.
The Bathypelagic Zone, informally known as the Midnight Zone, is 1,000-4,000 meters deep, resulting in a total absence of sunlight. Bioluminescence, light produced by organisms, is the only source of light. Food is scarce. Only 5% of food from the Epipelagic Zone reaches the Bathypelagic Zone.
The epipelagic zone is vast, and is the home for most pelagic fish. The zone is well lit so visual predators can use their eyesight, is usually well mixed and oxygenated from wave action, and can be a good habitat for algae to grow. However, it is an almost featureless habitat.
