About 71% of the surface of the Earth is covered by the ocean, a huge body of saltwater. It makes up the bulk of the hydrosphere and is home to 97% of the planet's water. There are five distinct regions of the ocean on the surface of the Earth: the Pacific, Atlantic, Indian, Southern, and Arctic.
The ocean is home to a wide variety of marine life and is the planet's biggest ecosystem. Humans rely heavily on the water for their food, transportation, and leisure needs. The ocean controls the Earth's temperature and weather patterns and is an essential component of the water cycle. The health of the ocean ecosystem and the effects of human actions on marine life, such as pollution, overfishing, and climate change, make the ocean susceptible.
Among the several marine habitats are the open deep sea, saltwater wetlands, coral reefs, estuaries, mangroves, sandy beaches, kelp forests, polar marine, and others. Marine ecosystems, the largest aquatic ecologies on Earth, are situated in salty oceans.
These environments stand in contrast to freshwater ecosystems, which contain less salt. Over 70% of the Earth's surface is made up of marine waters, which make up more than 97% of the planet's water. The biological community of species with which they are linked and their physical surroundings define marine ecosystems.
Brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks are among the several classes of species that may be found in marine habitats. The pelagic environment, which includes the neritic and oceanic zones, and the benthic environment, which includes the other three zones: intertidal, sublittoral, and abyssal, make up the five primary marine ecosystems. Large percentages of the world's population rely on marine ecosystems for food, employment, and other ecosystem services.
Oceans have a tremendous impact on Earth's climate. They regulate the weather, regulating precipitation, droughts, and floods. They modify the temperature as well. The ocean has a significant influence on the planet's weather and climate since it covers 70% of the planet's surface. The ocean influences weather and climate by collecting solar energy, distributing heat and moisture around the world, and producing weather systems.
The ocean serves as the planet's largest carbon sink by absorbing excess heat and energy from growing greenhouse gas emissions locked in the Earth's system. Climate patterns will shift globally as a result of changes in ocean temperatures and currents brought on by climate change.
Climate change can have a major impact on marine life and the health of the ocean ecosystem, as it affects the ocean's capacity to absorb carbon dioxide from the atmosphere. In addition to being a crucial part of the Earth's climate system due to the ocean's involvement in climate regulation, the ocean ecosystem must be safeguarded and conserved.
There are numerous differences between marine and freshwater habitats. Marine ecosystems thrive in waters with a high salt concentration, whereas freshwater ecosystems live in waters with reduced salt content. Marine waters span more than 70% of the Earth's surface and contain more than 97% of the planet's water, whereas freshwater environments include ponds, lakes, rivers, and streams.
The richness of marine ecosystems exceeds that of freshwater environments. Marine species must be adapted to living in a salty environment, whereas freshwater organisms must be suited to living in a salty environment.
Water's physical and chemical properties differ between marine and freshwater settings, impacting the types of species that may survive in each. Large portions of the world's population rely on marine environments for important ecosystem services, food, and employment, whereas freshwater ecosystems offer drinking water and irrigation for agriculture. Human use of marine and freshwater habitats, as well as pollution, pose severe threats to their stability.

The diversity of ocean life is stunning and a testament to how adaptable and hardy the creatures that live there are. The ocean is a treasure trove of fascinating and lovely creatures that are a wonder to behold, from the vibrant coral reefs to the enigmatic depths of the deep sea.
An estimated 25% of all marine life depends on coral reefs for habitat and food, making them some of the planet's most diverse ecosystems. A wide variety of fish, crustaceans, and other marine creatures can be found in coral reefs, along with vibrant corals and sponges that create a breathtaking visual display.
Sharks are frequently perceived as vicious predators, but they are also vital components of the ocean ecosystem. Sharks are diverse animals that have over 500 different species and range in size and shape from the tiny pygmy shark to the enormous whale shark.
One of the biggest animals on the planet, whales are essential to the health of the ocean ecosystem. Whales come in a variety of species, each with its own distinct traits and behaviors. These magnificent animals, from the acrobatic humpback whale to the elusive blue whale, are proof of the splendor and variety of ocean life.
Sea turtles are amazing animals that have existed for more than a hundred million years. Sea turtles come in seven different species, each with distinctive traits and habitats. Due to their gentle nature and distinctive beauty, these graceful creatures are cherished by many people as well as essential components of the ocean ecosystem.
A wide variety of bizarre and fascinating creatures that are rarely observed by humans reside in the deep ocean. These animals, from the bioluminescent anglerfish to the giant squid, have evolved to survive in one of the harshest environments on earth, and their distinctive traits are proof of the astounding diversity of ocean life.
