A non-profit organisation for the study and the conservation of the marine environment

Tethys has contributed since 1986 to marine conservation, at national and international levels, through the provision of scientific knowledge.

The Institute has been investigating the ecology of marine species,

most notably whales and dolphins, in research campaigns involving paying volunteers,

that are among the earliest citizen science projects in the Mediterranean.
