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 ...

Three different morphotypes of males exist. [13] The first stage is called "small male" (SM); this smallest stage has short, nearly translucent claws. If conditions allow, small males grow and metamorphose into "orange claws" (OC), which have large orange claws on their second chelipeds, which may have a length of 0.8 to 1.4 times their body size.

Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
This vast area spans both the Asian and Australian biogeographic zones, resulting in a unique and rich array of flora, fauna, and marine life. [56] [57] Indonesian archipelago diverse ecosystems, ranging from lush rainforests to mangroves and savannas, support a variety of plant life. The archipelago is home to approximately 28,000 species of ...
Geological obstacles and ocean currents most likely have an impact on the distribution of the Indonesian coelacanths, which are restricted to particular areas of the country (in contrast, L. chalumnae is found throughout the western Indian Ocean). Living in the lightless depths of the ocean, the Indonesian coelacanth has certain visual adaptations.
Ocean deoxygenation is an additional stressor on marine life. Ocean deoxygenation is the expansion of oxygen minimum zones in the oceans as a consequence of burning fossil fuels. The change has been fairly rapid and poses a threat to fish and other types of marine life, as well as to people who depend on marine life for nutrition or livelihood.
Marine geology or geological oceanography is the study of the history and structure of the ocean floor. It involves geophysical , geochemical , sedimentological and paleontological investigations of the ocean floor and coastal zone .
