Giant squid are elusive deep-sea animals with razor-toothed suckers and eyes the size of dinner plates. Images, videos, and facts from around the world. Giant squid live up to their name: the largest giant squid ever recorded by scientists was almost 43 feet (13 meters) long, and may have weighed nearly a ton. You’d think such a huge animal would be hard to miss. But because the ocean is vast and giant squid live deep underwater, they remain elusive and are rarely seen: most of what we know comes from dead carcasses that floated to the surface and were found by fishermen.

The Gulf and Caribbean Fisheries Institute (GCFI) was founded in 1947 to promote the exchange of current information on the use and management of marine resources in the Gulf and Caribbean region. From its beginning, GCFI has endeavored to involve scientific, governmental, and commercial sectors to provide a broad perspective on relevant issues, and to encourage dialogue among groups that often operate in relative isolation from one another. For 37 years, GCFI operated as an informal association under the sponsorship of the University of Miami. In 1985, with encouragement from the University, GCFI became an independent not-for profit corporation formally dedicated to its original purposes. Marathon, Florida

Museum of Comparative Zoology, Ichthyology Department. The Ichthyology collection houses recent bony and cartilaginous fishes. Ichthyology has been studied at Harvard since long before the founding of the Museum of Comparative Zoology in 1859. By the late 1700s, William Dandridge Peck, the first professor of Natural History at Harvard, had collected and published on New England fishes. Peck's specimens were skinned, dried and glued to paper sheets; some are still in the MCZ collection to this day. After the MCZ was founded the fish collection grew rapidly and has had a long history of active ichthyological research.

Just like the ocean, there are depths to what we do as marine biologists. That's our goal here, to show the different ways that a career in marine science can take you, what being a marine biologist really means, and how you can help our oceans. Here we believe that being a marine biologist is so much more than simply studying the ocean's living creatures. Oceanographers, engineers, videographers, conservationists, and every day folk all fall under the ocean’s spell. What does it take to work on the ocean, to help save our seas? We'll be exploring these topics in depth on this website and over at our podcast So You Want to Be a Marine Biologist. We learn from people who are working hard to better protect our oceans with their inspiring research and projects. We break down scientific jargon into bite sized pieces, and cover concepts important to marine research. We explore how to get those amazing jobs (like studying dolphins and coral) and what it takes to contribute to marine science. We show you how you, just one person, can make a huge impact. We reveal the real side of being a marine biologist. If you love the ocean and its mysteries, you’re in the right spot

The aim of a World Register of Marine Species (WoRMS) is to provide an authoritative and comprehensive list of names of marine organisms, including information on synonymy. While the highest priority goes to valid names, other names in use are included so that this register can serve as a guide to interpret taxonomic literature. The content of WoRMS is controlled by taxonomic and thematic experts, not by database managers. WoRMS has an editorial management system where each taxonomic group is represented by an expert who has the authority over the content, and is responsible for controlling the quality of the information. Each of these main taxonomic editors can invite several specialists of smaller groups within their area of responsibility to join them. Flanders, Belgium
