Subterranean fauna is found worldwide and includes representatives of many animal groups, mostly arthropods and other invertebrates.However, there is a number of vertebrates (such as cavefishes and cave salamanders), although they are less common.
The amount of dissolved oxygen in a water body is frequently the key substance in determining the extent and kinds of organic life in the water body. Fish need dissolved oxygen to survive, although their tolerance to low oxygen varies among species; in extreme cases of low oxygen, some fish even resort to air gulping. [25]
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so. Chionophiles are any organisms ( animals , plants , fungi , etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning " snow ", and -phile meaning "lover").
Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...
The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment. This sun-drenched habitat can be defined as roughly one metre in depth, as nearly half of UV-B is attenuated within this first meter. [ 2 ]

Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
