Marine Life
- Census of Marine Life – The Census of Marine Life was a global network of researchers in more than 80 nations engaged in a 10-year scientific initiative to assess and explain the diversity, distribution, and abundance of life in the oceans.
- Coastal fish – Coastal fish, also called offshore fish or neritic fish, are fish that inhabit the sea between the shoreline and the edge of the continental shelf.
- Coral reef fish – Coral reef fish are fish which live amongst or in close relation to coral reefs.
- Deep sea communities – Deep sea communities currently remain largely unexplored, due the technological and logististical challenges and expense involved in visiting these remote biomes.
- Deep sea creature – The term deep sea creature refers to organisms that live below the photic zone of the ocean.
- Deep sea fish – Deep-sea fish is a term for any fish that lives below the photic zone of the ocean.
- Deep-water coral – The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond where water temperatures may be as cold as 4°C.
- Demersal fish – Demersal fish live on or near the bottom of the sea or lakes.
- Marine bacteriophage – Marine bacteriophages or marine phages are viruses that live as obligate parasitic agents in marine bacteria such as cyanobacteria. Their existence was discovered through electron microscopy and epifluorescence microscopy of ecological water samples, and later through metagenomic sampling of uncultured viral samples.
- Marine invertebrates – Marine invertebrates are multicellular animals that inhabit a marine environment and are invertebrates, lacking a vertebral column.
- Marine larval ecology – Marine larval ecology is the study of the factors influencing the dispersing larval stage which is exhibited by many marine invertebrates and fishes.
- Marine mammal – Marine mammals, which include seals, whales, dolphins, and walruses, form a diverse group of 128 species that rely on the ocean for their existence. They do not represent a distinct biological grouping, but rather are unified by their reliance on the marine environment for feeding. Marine mammals can be subdivided into four recognised groups; cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), and fissipeds, which are the group of carnivores with separate digits (the polar bear, and two species of otter). Both cetaceans and sirenians are fully aquatic and therefore are obligate ocean dwellers. Pinnipeds are semi-aquatic; they spend the majority of their time in the water, but need to return to land for important activities such as mating, breeding and molting. In contrast, both otters and the polar bear are much less adapted to ocean living. While the number of marine mammals is small compared to those found on land, their total biomass is large. They play important roles in maintaining marine ecosystems, especially through regulation of prey populations. The level of dependence on the marine environment for existence varies considerably with species.
- Marine reptile – Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semi-aquatic life in a marine environment.
- Marine vertebrate – Marine vertebrates are vertebrates which live in a marine environment.
- Paradox of the plankton – In aquatic biology, the paradox of the plankton is the name given to the situation where a limited range of resources supports a much wider range of planktonic organisms.
- Pelagic fish – Pelagic fish live near the surface or in the water column of coastal, ocean and lake waters, but not on the bottom of the sea or the lake.
- Seabird – Seabirds are birds that have adapted to life within the marine environment.
- Seashore wildlife – Seashore wildlife Habitats exist from the Tropics to the Arctic and Antarctic.
- Wild fisheries – A fishery is an area with an associated fish or aquatic population which is harvested for its commercial value. Fisheries can be marine or freshwater. They can also be wild or farmed.

Famous quotes containing the words marine and/or life:
“God has a hard-on for a Marine because we kill everything we see. He plays His game, we play ours.”
—Stanley Kubrick (b. 1928)
“There mark what ills the scholar’s life assail,
Toil, envy, want, the patron, and the gaol.”
—Samuel Johnson (1709–1784)
