[2] [3] It tells the story of a group of anthropomorphic farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy.
Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system. Biological oceanography mostly focuses on the microorganisms within the ocean; looking at how they are affected by their environment and how that affects larger marine creatures and their ecosystem.

He wrote extensively on the subject, and his book, The Physical Geography of the Sea (1855), was the first comprehensive work on oceanography to be published. In 1825, at 19, Maury obtained, through U.S. Representative Sam Houston , a midshipman's warrant in the United States Navy. [ 1 ]
Nekton, on the other hand, are larger and swim at biologically high Reynolds numbers (10 3 to 10 9), where inertial flows are the rule and eddies (vortices) are easily shed. Many organisms, such as jellyfish and most fish, start life as larva and other tiny members of the plankton community, swimming at low Reynolds numbers, but become nekton ...
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.
Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system. Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.
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.
More than 1100 species of fish [33] have been recorded in the Red Sea, and around 10% of these are found nowhere else. [34] This also includes around 75 species of deepwater fish . [ 33 ] The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline ; these fringing reefs are 5000–7000 years old and ...
