Monk seals are the only completely tropical species of seal in the world and are in trouble.  Centuries of human exploitation and habitat destruction have caused the remaining populations of Mediterranean monk seals (Monachus monachus) and Hawaiian monk seals (Monachus schauinslandi) to drop to perilously low numbers, while the Caribbean monk seal (Monachus tropicalis) has become extinct.  Scientists from Greece and the U.S. are in a race against time and are working together from opposite sides of the World to save the remaining monk seals. The MOm/Hellenic Society for the Study and Protection of the Monk Seal is a non-profit, non-governmental organization with over 20 years of experience in the research and conservation of Mediterranean monk seals in Greece and abroad. Researchers at MOm have gained rare insights in the biology and behavior of Mediterranean monk seal by utilizing innovative technology that has enabled the seals to be monitored remotely inside their breeding caves.  Current and future collaborations with U.S. scientists who study Hawaiian monk seals will provide important insights into new ways to help the two remaining species of monk seals survive into the future.
