A Yellow Tang Marine life is concerned with the plants, animals and other organisms that live in the ocean. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. For this reason marine life encompasses not only organisms that only lives in a marine environment, but also those whose lives revolve around the sea. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms produce much of the oxygen we breathe and probably help regulate the earth's climate. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. Marine biology covers a great deal, from the microscopic, including plankton and phytoplankton, which can be as small as 0.02 micrometres and are both hugely important as the primary producers of the sea, to the huge cetaceans (whales, dolphins and porpoises) which reach up to a reported 33 metres (109 feet) in length in the case of the blue whale.

Commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the USA, Japan and Western Europe. The total global production of farmed shrimp reached more than 1.6 million tonnes in 2003, representing a value of nearly 9,000 million U.S. dollars. About 75% of farmed shrimp is produced in Asia, in particular in China and Thailand. The other 25% is produced mainly in Latin America, where Brazil is the largest producer. The largest exporting nation is Thailand. More on Shrimp farms Felix Anton Dohrn ( September 29, 1840 - September 26, 1909) was a prominent Darwinist and the founder and first director of the Stazione Zoologica, Naples, Italy. Dohrn was born in Stettin, Pomerania, present day Poland, in 1840, into a wealthy middle class family. His grandfather, Heinrich Dohrn, had been a wine and spice merchant, and had made the family fortune by trading in sugar. This wealth allowed Anton's father, Carl August, to devote himself to his various hobbies; travelling, folk music and insects. Anton, the youngest son, read zoology and medicine at various German universities (Königsberg, Bonn, Jena and Berlin), with little application or enthusiasm for his studies. More on Anton Dohrn First animals that spent their entire lives without any oxygen (anoxic waters) were discovered in depths of Mediterranean Sea. They belong to three new species from phylum Loricifera (one of new species pictured). Triggerfishes are the brightly coloured fishes of the family Balistidae. (pictured) Marked by lines and spots, they inhabit warm coastal waters of the Atlantic, Mediterranean and the Indo-Pacific. Marbled hatchetfish are the only known fish that can actually fly by jumping into the air and moving their fins. The sea otter often keeps a stone tool in its armpit pouch. Some cichlid fish, crocodiles and frogs keep their eggs or young in their mouths or stomachs. The Horseshoe crab has blue, copper based blood.
