The Marine Life Portal

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 can only live 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.

A shrimp farm is an aquaculture business for the cultivation of marine shrimp or prawns for human consumption. 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.

Selected biography

George Boulenger.

George Albert Boulenger (born Brussels, Belgium, October 19, 1858 died Saint Malo, France, November 23, 1937) was a British zoologist.

Boulenger was the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart de Valenciennes. He graduated in 1876 from the Free University in Brussels with a degree in natural sciences and worked for a while at the Museum of Natural History of Brussels as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the Muséum National d'Histoire Naturelle in Paris and the British Museum in London.

In 1880, he was invited to work at the Natural History Museum by Dr. Albert C. L. G. Günther and assigned to the task of cataloguing the amphibians in the collection. His position in the British Museum meant that he had to be a civil servant of the British Empire, and so became a naturalized British subject. In 1882 he became a first-class assistant in the Department of Zoology and remained in that position until his retirement in 1920.

The giant grouper (Epinephelus lanceolatus), also known as the brindle bass and as the Queensland grouper in Australia, is the largest bony fish found in coral reefs, and the aquatic emblem of Queensland, Australia. It is found throughout the Indo-Pacific region, with the exception of the Persian Gulf. The species can grow as large as 2.7 meters (9 ft) long, weighing up to 400 kg (880 lb). They are fairly common in shallow waters and feed on a variety of marine life, including small sharks and juvenile sea turtles.
