Established in 2017



We are a small group committed to doing our little bits to fight against the pollution in our oceans and conserve our slowly degrading biodiversity. We work as part of PADI Aware's dive against debris program, providing long-term monitoring of our adopted dive site, the beautiful coral reef of Tung Ping Chau island and also take part in other volunteer actions.

Where does the name come from?

The founder of the group, Eszter, is an animal behaviour scientist. Her passion towards marine mammals and aquatic research inspired the name, which comes from Latin and means bottlenose dolphin.

The team

DR. Eszter Matrai
Founder and team leader

Moving to Hong Kong allowed my childhood dream to come true and learn to scuba dive. Even before learning diving, I visited Tung Ping Chau for snorkelling on multiple occasions and I was mesmerised by its variety of corals and fish speciesWhen I finally became a diver, I returned to Tung Ping Chau regularly and in a few years, I noticed the gradual decline of the reef. As a marine park and a coral diversity hotspot, Tung Ping Chau plays a crucial role in Hong Kong's marine biodiversity. That is why I decided to adopt Tung Ping Chau and to organise regular cleanup events to do everything I can to preserve this beautiful place. As a scientist,believe that pairing our cleanup efforts with appropriate data collection is critical to making a difference. Our survey data have provided a valuable addition to the international Dive Against Debris map. Since 2017 the number of members of our team has grown 8x. I am honoured and humbled by the help of over 100 volunteers over the years. Thank you all!

Rick has not only been participating in our cleanup events, but he also took part in educational talks and presentations. Dive safety is his number one priority, which is extremely important when the dive takes place at a remote location such as Tung Ping Chau. Rick's sense of responsibility towards the group and the protection of the marine flora and fauna makes him a role model for the group.

Casey leung
Core member

Casey was one of the first members of Tursiopsdivers! She is an advanced diver with nine years of experience. As a future veterinarian, she has a deep appreciation towards nature and the ocean. Casey and I have spent many hours simply staring at a small shrimp or even a common puffer fish without getting bored. We even go snorkelling between dives, and we have both been described as a little crazy in a good way. Whenever Casey is in Hong Kong, she is always ready to help with our surveys. Let it be a calm and clear explanation for newbies, sorting of the marine debris or a simple equipment check, Casey is always ready to help!
