Fundación Cethus was created in 1992 by a group of researchers and specialists focused on diverse disciplines with the aim of researching, spreading information about and conserving the dolphins and whales of the Argentine Sea. Fundación Cethus chose to focus specifically on cetaceans because of the high level these cetaceans occupy in the sea food pyramid in the marine environment, similar to that we humans occupy in our environment.

The purpose of the Malpelo and other Marine Ecosystems Foundation is to preserve Colombian biological diversity, the conservation of the natural resources and their sustainable use with an emphasis on the marine and coastal environment. Their projects include protection of shark breeding grounds, coral reef protection and restoration, combatting marine and plastic pollution, amongst others. Their work involves research, surveillance and observation, education and ecotourism, and political advocacy.

Rewilding Argentina is a foundation created to face and reverse the extinction of species and the resulting environmental degradation, recovering the functionality of ecosystems and promoting the well-being of local communities. In 2017 the Rewilding Argentina Foundation created the Marine Conservation Program Without Blue No Hay Verde (No Blue No Green) aimed at protecting the habitat of the Patagonian sea, its coasts and the species that exist there. The goal is to protect 30% of the Argentine Sea to ensure the conservation and regeneration of its ecosystems through the creation of a network of marine and coastal protected areas.

Founded in 1977 and since 1988 Vida Silvestre represents in Argentina the World Wildlife Fund (WWF), the Argentine Wildlife Foundation)has been working on solving the main environmental issues of Argentina. Its mission is "to propose and implement solutions for conserving nature, promoting the sustainable use of natural resources and responsible behaviour on the part of mankind in the context of climate change'. This includes a significant marine component, including establishing marine protected areas and a sustainable fishing model for the country, and protecting marine species including cetaceans.

GEOTA is an environmental protection group in Portugal. The name translates as Study Group on Spatial Planning and Environment.

GRIS consists of researchers dedicated to the study of cartilaginous fish (sharks, rays and chimeras) in order to promote research, protection, conservation and management of these vertebrates.

Galápagos Conservancy is dedicated exclusively to the long-term protection and restoration of the Galápagos Islands, including more than 2,000 species found nowhere else on Earth. As a leading direct on-the-ground conservation action, they work with partners, including the Galápagos National Park Directorate, to save imperilled species, build a more sustainable society, and rewild the complex ecosystems of the Archipelago. Collectively, their members represent the largest source of private funding for conservation in the Islands.

GRD was founded by Rollo Gebhard, German mariner and documentary filmmaker, and is dedicated to the conservation of wild dolphins and their habitats by supporting research, promoting public awareness and lobbying for better protection. The organization works for a ban of ecologically unacceptable fishing practices, such as driftnets, which cause the senseless death of hundreds of thousands of dolphins, whales, seals, sharks, and seabirds every year, or setting purse-seine nets around dolphin schools to catch tuna.

Ghost Diving is run by volunteer divers who have specialized in the removal of lost (ghost) fishing gear and other marine debris since 2009. Originally named Ghost Fishing Foundation, in 2020, the entire global organization was reorganized and renamed into Ghost Diving Foundation. Now spread over 16 countries in the world where local diving teams identify as Ghost Diving chapters, including France, Adriatic, Egypt, Germany, Greece, Hong Kong, Korea, Lebanon, New Zealand, Philippines, Poland, Spain and the UK. They are actively raising awareness about the "ghost fishing" issue on a global scale.

Ghost Fishing UK works to remove Abandoned, Lost and Discarded Fishing Gear, otherwise known as ‘Ghost Gear’. The purpose is to remove from the marine environment the ghost gear which presents potentially lethal hazards to marine life and scuba divers. Volunteer scuba divers, who have extensive training in advanced diving practices, dive to remove ghost nets and raise awareness through education about plastics and ghost fishing gear problems. The organisation formed in 2015 at an inaugural project in Scapa Flow, Orkney. In 2021 Ghost Fishing UK were winners of the 'Best Plastic Campaign' at the Plastic Free Awards.

Gili Eco Trust was founded to protect coral reefs around Gili islands from irresponsible and destructive fishing, educating fishermen about legal techniques of fishing and authorized zones so that there would be no more bad fishing practices.
In addition to marine conservation, they have expanded their activities to waste management and sustainable eco tourism.

The Gili Shark Conservation Project is an award-winning conservation and data collection program, the first of its kind in the Gili Islands in Indonesia. Situated on the beautiful island Gili Air, they work around all of the Gili islands: Gili Air, Gili Meno, and Gili Trawangan. The goal of their shark research project is to raise awareness for shark- and marine conservation but also to assist the local community and helping the Gili's to become plastic-free. They aim to protect and restore the coral reef environment within the Gili Matra Marine Recreational Reserve and to help to create the first recognized shark nursery ground in Indonesia. To achieve this goal they conduct research using multiple research methods including; underwater roving video surveillance, roving survey dives, photographic identification, coral health index surveys, coral restoration, and land & marine based time-lapse projects. Via weekly conservation classes at the local school and a Plastic Free Paradise Campaign, they are educating the local community and visitors of the Gili Islands about the importance of our ocean and what we can do to protect it.
