aquatic : growing or living in or frequenting water — Webster
Aquatic ecosystem An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. — Wikipedia
Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth’s surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone, where solid objects are rare and the surface of the water is the only visible boundary. The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 25–32 meters (82–105 feet) in length. Marine ecology is the study of how marine organisms interact with each other and the environment. — Wikipedia

Animals in hard-to-reach places, especially strange, 'unattractive,' animals, may completely escape our attention. We don't know what their role is in the environment. In fact, we don't even know they exist. New research may double the number of species of a little-known marine creature, based on DNA studies of its larvae. […]
Plastic pollution harms the bacteria that help...

Ten percent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a new study. […]

Unravelling the secrets of the relationship between coral and the algae living inside it will help prevent coral bleaching, researchers believe. By using genomic data to look for genes that enhance resilience in the algae, researchers hope to help coral adapt to the environmental shifts created by climate change. […]

Climate change affects all life on Earth, but it poses unique challenges for aquatic species. For example, as water warms it holds less dissolved oxygen than cooler water. As a result, the world's oceans, coastal seas, estuaries, rivers and lakes are undergoing a process known as "deoxygenation." […]
Water flea can smell fish and dive into the dark...
on May 9, 2019 at 1:22 pm
Water fleas, or Daphnia, ensure their survival by reacting to a signal substance of their predators (fish) with flight. The zoologist Meike Anika Hahn from Professor Dr. Eric von Elert's research group at the University of Cologne's Institute of Zoology has identified this chemical messenger substance, which the fish releases into the water of lakes. When the water flea detects the substance 5α-cyprinol sulfate—a bile salt from the fish—it leaves the upper water layers and […]
