John Edward Gray wrote nearly 500 papers, including many descriptions of species new to science. These had been presented to the Museum by collectors from around the world, and included all branches of zoology, although Gray usually left the descriptions of new birds to his younger brother and colleague George. Gray was also active in malacology, the study of molluscs. John Edward Gray was buried at St Mary's Church, Lewisham. Gray was one of the most prolific taxonomists in the history of zoology. He described more than 300 species and subspecies of reptiles, only surpassed by his successors at the British Museum, George
Branches of science of organisms within and among ecosystems. Oceanography, or marine biology, is the branch of Earth science that study of the ocean . It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it: biology, chemistry, geology, meteorology, and physics as well as geography.
