The International Otter Survival Fund (IOSF) was inspired by observing otters in their true natural environment. Because the otter lives on land and in the water and is at the peak of the food chain it is an ambassador species to a first class environment. IOSF was set up to protect and help the 13 species of otter worldwide through a combination of compassion and science. It supports projects to protect otters, which will also ensure that we have a healthy environment for all species, including our own.
