Stars of sailors’ stories, legends and myths, dolphins are some of the most exciting and beloved marine mammals. We find depictions of dolphins in ancient mosaics, buildings, and pottery, while we also encounter them in Greek mythology. Dolphins, together with whales and porpoises belong to cetaceans. They have their own communication codes of communication. They can orient themselves, locate their food, and communicate with each other through an echolocation system, and they can hear frequencies ten times higher than those humans can hear. These creatures are very smart, social, and live in communities that include thousands of individuals.


However, dolphins’ greatest “natural enemy” are, unfortunately, us humans. Accidental capture in fishing gear or intentional killings, overfishing, plastic, oil and chemical pollution, climate change, and the degradation of marine habitats are threatening dolphins and leading to the long-term reduction of their populations in Greek seas.


Each dolphin has its own audio signature. In short, it has its own “name”.

Dolphins swim at an average speed of 37 km/h

Dolphins sleep with only half their brain. The other half remains awake in order to maintain basic navigation and breathing.


If the dolphin population drops, it will irreversibly disrupt the marine food chain and the balance of the entire marine ecosystem. To put it simply, as long as we spot dolphins in our seas, we can be confident that fish populations are relatively sufficient. At WWF Greece, we aim to preserve the natural habitat in which dolphins live and reproduce in the Greek seas. This is why we are monitoring dolphin populations, and applying pressure to address key threats within and outside Marine Protected Areas such as overfishing, which has resulted in a shrinking of fish populations that dolphins feed on, and on incidental catch by promoting solutions to change fishing practices and limit losses for fishersWe are also fighting to stop  oil and natural gas drilling in the Ionian Sea and Crete. Every day we take important steps with those who believe in a healthy sea.


Adopt a dolphin! With a symbolic adoption, you can become an active ally in our struggle to save these unique and threatened species of Greece and to keep our sea alive.
