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.

Emperor penguins.jpg

The Emperor Penguin (Aptenodytes forsteri), at 1.3 metres (3 ft 9 in) tall and 32 kilograms in mass, is the tallest and heaviest of all penguins. It is the only penguin that breeds during the winter in Antarctica. Emperor Penguins eat mainly crustaceans (such as krill) but also occasionally indulge in small fish and squid. In the wild, Emperor Penguins typically live for 20 years, but some records indicate a maximum lifespan of around 40 years. The Emperor Penguin should not be confused with the King Penguin or the Royal Penguin.

Adults average about 1.3 metres (3 ft 9 in) and weigh 30 kilograms (75 lb) or more. The head and wings are black, the abdomen white, back bluish grey, and the bill is purplish pink. On the sides of the neck, there are two golden circular stripes.

Like the King Penguin counterpart, a male Emperor Penguin has an abdominal fold, the "brood pouch", between its legs and lower abdomen.

Selected biography

Edward Drinker Cope

Edward Drinker Cope (July 28, 1840–April 12, 1897) was an American paleontologist and comparative anatomist.

Cope was born in Philadelphia to Quaker parents. At an early age he became interested in natural history, and in 1859 communicated a paper on the Salamandridae to the Academy of Natural Sciences at Philadelphia. It was about this time that he became affiliated with the Megatherium Club at the Smithsonian Institution in Washington, D.C. He was educated partly in the University of Pennsylvania and, after further study and travel in Europe, was appointed curator to the Academy of Natural Sciences in 1865, a post which he held until 1873. From 18641867 he was professor of natural science at Haverford College, and in 1889 he was appointed professor of geology and palaeontology by the University of Pennsylvania.

The Magellanic penguin (Spheniscus magellanicus) is a South American penguin, breeding in coastal Argentina, Chile and the Falkland Islands, with some migrating to Brazil. It is the most numerous of the Spheniscus penguins. Its nearest relatives are the African Penguin, the Humboldt Penguin and the Galápagos Penguin.
