The Blue World Institute of Marine Research and Conservation

Did you know that the area around the island of Lošinj is home to more than 200 bottle-nose dolphins?

It was in 1987 that the Tethrys Research Institute started to research the groups of bottle-nose dolphins in the waters of islands of Cres and Lošinj within the project of research of ecology, social structure, and biology of these interesting and best-studied groups in the entire Mediterranean. In 1999, the research titled Adriatic Dolphin Project was taken over by the Blue World Institute in Veli Lošinj.

Don't miss Dolphin Day that has been celebrated on 1st July in Veli Lošinj since 1993!

The cuts and scars on their back fins, the part of their bodies which is most easily observed when they come up for air, was the identifying element that helped estimate 200 animals in the area of Cres and Lošinj, most of which have also been identified.

Although the most adaptive and most resilient of all whales, given many threats that the dolphins face, all marine mammals in Croatia have been protected since 17th May 1995.  The ships hinder their movement, engines interfere with their orientation in space and their communication, and they often end up entangled in the threatening fishing nets.

Adopt a dolphin!

If you want to support protection of environment, contribute to the marine research and conservation of dolphins, join the “Adopt a Dolphin” campaign. If you adopt one either in person or online on the Blue World Institute website, you will receive the package for adoptive parents from the Institute that contains a photo of the dolphin you’ve just adopted and contributed to its protection, as well as the annual magazine Akvamarin.


By partaking in the Blue World's activity "Adopt a Dolphin", you are supporting the Adriatic Dolphin Project, our research efforts and protection of the bottle-nose dolphins in the area of Cres and Lošinj, as well as backing the protection of their environment.

Volunteer at the Blue World!

For all of you who want to help collect and compile research data during summer months when observations of the dolphins are most often, doing it either in the field or in the Institute,  you can contribute as an eco volunteer.

Becoming a volunteer means that you join the Blue World crew in Veli Lošinj and help fund the research !
