Eco Koh Tao

Yesterday was a full day of cleaning up, both on land and in the ocean!

Thank you to everyone who helped! It was amazing to have so many people join in the fun for a good cause.

The day started with a morning beach clean. Congratulations to our winning team (Ryan and Anatoly) for picking up the most trash, 8.2 kg! In total we managed to collect 14 kg in 45 minutes.

In the afternoon we went out for two Dives Against Debris, where we go fun diving while collecting debris. When we return from a dive all the debris found is categorized, recorded and reported. We had 3 teams go out and in total we collected over 12kg of trash.

Great job everyone & Thank you!

Eco Koh Tao

Yesterday we went out for a fun dive to collect these Drupella Snails πŸ˜€

Drupella snails are found throughout the indo-pacific ocean and they feed on living coral tissue. Overpopulation of these snails has lead to a dramatic loss in living coral, they also reduce coral resilience and recovery.

It's a really good feeling to go diving while contributing to marine conservation. These dives will also help fine tune important skills such as buoyancy.

Join us for the next one!
