Orcas (formerly known as killer whales), Orcinus orca, are actually dolphins. They are the largest of the dolphin family (Family Delphinidae with about 32 species, including the dolphins, pygmy killer whales, Feresa attenuata, and false killer whales, Pseudorca crassiddens).
Next to humans, orca are the most widely distributed mammal. Orca inhabit all oceans of the world but are most numerous in the Arctic, the Antarctic and areas in nutrient-rich cold water upwellings. They have been sighted along the shores of Washington, Oregon, California, Baja California, and along the eastern coast of the United States. More...

Marine Conservation
Find out about the issues marine life currently faces and what we can all do to help (and why we should). Hear from leading scientists and advocates about the science involved in Marine Conservation Biology and discover what organizations around the world are also doing in the fight to save our ocean, its life and ultimately ourselves. For a wonderful introduction to wildlife conservation, check out the 12 essays by Dr. Moyle and join the discussions in our forums and our blog, on Facebook or follow us on Twitter.
Marine Life
Sharing the wonder of marine life is what started MarineBio, so in this section we explore information on the science, biology, taxonomy, morphology, etc. of the fascinating marine life that inhabits our ocean. Browse our marine life databases where we're working to provide home pages for the ~4,000 most common and threatened/endangered marine species.
Volunteers from around the world are working to help increase our number of species and your donations and memberships are helping to make it happen as soon as possible.
- Marine Species Databases - Browse or search our species home pages for marine birds, fishes, reptiles, seals & sea lions, sharks & rays, squid & octopuses, whales & dolphins, and more....

The Ocean
This section of MarineBio explores some of what is known about the ocean and provides an online introduction to marine biology and ocean science. Here we begin the journey into this planet's largest living space — The Ocean.
Find out about the history of the ocean, its chemistry, its currents and tides and its various habitats or zones such as the continental shelves, the open ocean and the deep sea.
Education & Careers
For current and future students of marine science, we provide updated links to resources, academic institutions, and marine labs offering curricula in the various disciplines related to the study of the ocean and marine life.
We also provide job resources for those completing their studies: Job Resources ~ Careers & Education @Plankton Forums

The ocean is our earth's greatest natural resource. It is the place of origin for most life forms. Millions of people rely on the ocean for survival. Twelve million fishermen operate three million vessels landing around 90 million tons of fish each year, providing work for over 200 million people worldwide.
More than 60% of the global population live within 60 km of the coast. The ocean provides the majority of our oxygen and the rain itself. The ocean buffers the weather and helps regulate global temperature and manages vast amounts of our pollutants. More than 2 billion tons of carbon dioxide are absorbed by the ocean every year.
The ocean is home to some of the most amazing creatures on earth, ~80% of the world's biodiversity lives in the sea and there is still so much to be discovered. At least 100 million unnamed species live on the ocean floor alone. Thousands of pharmaceutical compounds have been isolated from marine animals and plants. The cures for HIV/AIDs, cancer, malaria, tuberculosis and leukemia, etc. could lie beneath the waves. The ocean is in our backyard, yet more is known about the Moon and Mars. We are just now beginning to understand the ocean and with that understanding comes the increasing realization that the ocean is in deep trouble. Marine conservation efforts so far are simply overwhelmed by the number and scale of the problems the ocean faces.
Please learn more about the ocean, its life, the problems it faces, and what you can do today to help protect and restore it, for all of us.
