Sunlit Ocean (Euphotic) Zone Animal Printouts

Ocean zonesThe 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. In clear water, the euphotic zone can be quite deep; in murky water, it can be only 50 feet deep. On average, it extends to about 660 feet (200 meters); the depth of the ocean averages about 13,000 feet or 4,000 m. The temperature in this zone ranges from 104 to 27 degrees F.

In this zone, there is enough light for photosynthesis to take place, so many plants and other photosynthetic organisms live in this zone and food is abundant. Photosynthesis is a process in which sunlight and carbon dioxide gas are converted into food (chemical energy contained in carbohydrates) and oxygen gas. Photosynthesis in the oceans creates approximately 90% of the Earth's gaseous oxygen. Most of the oxygen is produced by phytoplankton. These primary producers (also called autotrophs) are the first link in the food chain in the oceans. Because of this food source, many animals also live in this zone. In fact, most of the life in the ocean is found in this zone, although it is the smallest ocean zone in terms of volume of water.

Primary Producers (Algae, Phytoplankton, Plants): In the euphotic zone, photosynthesizers (autotrophs) include:

Animals: Examples of euphotic zone animals include most ocean fish (including sharks and rays), man-o'-war, jellyfish, sea turtles, seals, coral, and zooplankton. Some bottom-dwellers live in the euphotic zone - this zone is defined in terms of light, not depth.

Some of the animals in this zone have countershading. Countershading is when an animal is light on its underside and dark on its upper parts. When a predator looks down at a countershaded animal, it blends into the darker waters; whan a predator looks at a countershaded animal from below, the light underbelly disappears into the light. This adaptation helps camouflage the organism, hiding it from predators and allowing it to sneak up on prey. Most sharks, for example, are countershaded.
