Marine biology. Only 29 percent of the world surface is land.
The rest is ocean, home to the marine lifeforms. The oceans average nearly four kilometres in depth and are fringed with coastlines that run for 360,000 kilometres.[1][2] A large proportion of all life on Earth exists in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world[3] covering about 71% of the Earth's surface. Ocean. An ocean (from Ancient Greek Ὠκεανός, transc.
Okeanós, the sea of classical antiquity[1]) is a body of saline water that composes much of a planet's hydrosphere.[2] On Earth, an ocean is one of the major conventional divisions of the World Ocean, which occupies two-thirds of the planet's surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern, and Arctic Oceans.[3][4] The word sea is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.[5] Earth's global ocean[edit] Global divisions[edit] Various ways to divide the World Ocean.
Marine Conservation Organizations. MarineBio is deeply committed to marine conservation and founded on the concept that, by sharing the wonders of the ocean and marine life, people will be inspired to protect it.
We hope you will consider becoming a MarineBio Conservation Society member to help us bring the ocean and the conservation message to as many people as possible. There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming. We list them here both as a public service and to spread the word. Please Contact us if you have any comments, changes, or suggestions. » Invitation to fellow marine conservation groups For an objective annotated list of the organizations listed below and others, visit Mother Jones magazine's guide to environmental organizations.

Seahorses are truly unique, and not just because of their unusual equine shape.
Unlike most other fish, they are monogamous and mate for life. Rarer still, they are among the only animal species on Earth in which the male bears the unborn young. Found in shallow tropical and temperate waters throughout the world, these upright-swimming relatives of the pipefish can range in size from 0.6 inches (1.5 centimeters) to 14 inches (35 centimeters) long. Male seahorses are equipped with a brood pouch on their ventral, or front-facing, side. When mating, the female deposits her eggs into his pouch, and the male fertilizes them internally. Because of their body shape, seahorses are rather inept swimmers and can easily die of exhaustion when caught in storm-roiled seas. They anchor themselves with their prehensile tails to sea grasses and corals, using their elongated snouts to suck in plankton and small crustaceans that drift by.
