What are the things in the sea?
Animals such as seahorses, clownfish, and sea turtles all live on coral reefs. And corals themselves are animals! They grab food from the water using tiny tentacle-like arms. Kelp forests found along the coastlines of the Pacific and Antarctic Oceans also provide food and shelter for marine life.
What are animals under the sea called?
Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar bears. They are an informal group, unified only by their reliance on marine environments for feeding and survival.
What is in deep sea?
This is the deep sea. Most are familiar with the surface layer, which extends down 650 feet (200 m) and receives the most sunlight, allowing photosynthetic organisms like phytoplankton to convert sunlight to energy. It is the home of pods of dolphins, schools of fish, and shoals of sharks.
What is under the deepest ocean?
The average ocean depth is 2.3 miles . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
What are 3 things we get from the ocean?

How do aquatic animals get oxygen?
Water has oxygen too. Fish get the oxygen their bodies need by pumping water over their gills. Gills extract oxygen from water and send it into the fish’s blood stream. For this reason, most fish, and other aquatic animals that get oxygen from water, can’t survive on land very long.
What is deep below the ocean?
The abyssal plain is the relatively level deep seafloor. It is a cold and dark place that lies between 3,000 and 6,000 meters below the sea surface. It is also home to squat lobsters, red prawns, and various species of sea cucumbers. For these creatures food is scarce most of the time.
How deep can a human go underwater?
The maximum depth reached by anyone in a single breath is 702 feet (213.9 metres) and this record was set in 2007 by Herbert Nitsch. He also holds the record for the deepest dive without oxygen – reaching a depth of 831 feet (253.2 metres) but he sustained a brain injury as he was ascending.
How do oceans benefit humans?
The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
