In the SSI Marine Ecology Specialty program, you will learn how ocean organisms interact with each other and their environments. Go beyond simply identifying marine life and begin to understand the deeper connections that shape coral reefs and tropical ecosystems.
This course explores how energy flows through marine communities, how different habitats support one another, and how environmental pressures impact the underwater world. As you dive around Koh Tao, you will start to see the reef not as separate species, but as a living, interconnected system. By the end of the program, you will have a stronger ecological understanding of what you are seeing on every dive and a greater appreciation for how to protect it.
12:00-17:00 Marine Ecology academic session
16:30-17:00 Debrief and certification

We had four dives with Daan, Mike & Lukas. Awesome experience with supernice & helpful guys literally creating good times! It is also a lovely spot to hang around at the beach club with wonderful breakfast, delicious smoothies and great waiters. We came here several times and enjoyed it!
Goodtime offered a nice environment for me to obtain my OWD certification. I enjoyed the course works by SSI. My instructor, Daan Schouwstra, is experienced and detailed. I was lucky to have him. For beginners looking for OWD certification, Goodtime is an excellent choice here at Koh Tao. Please note that the 2.5 days program may not be enough for you to get certified. All trainings were in open water. I had prior OWD certification courses (like Referral Diver) done in cold water, and done 2 discovery dives in Maldives. The 2.5 days certification program is very condensed. I recommend you finished and passed the SSI OWD course works on their App prior to your arrival. Also, be prepare to swim 200 meters and tread 10 minutes in open water. Enjoy your dives! 🤙
First time diving and it was fantastic! Lisa explained everything very well, and afterward, we had a fantastic dive with her! I would recommend it to anyone visiting Koh Tao!
Our Diver Instructor Daan was the best I could have asked for, for my very first diving experience! He was patient and helpful to everyone in our group. Definitely want to dive again after such a positive day!! 🐟🐠🪼
Shai is an excellent diving instructor. He combines deep professional knowledge with a real passion for teaching and sharing his experience. Calm, supportive, motivating and FUN, he makes the learning process feel safe, enjoyable, and inspiring. Highly recommended.
We completed our Open Water certification with Goodtime on Ko Tao — and we already can’t wait to come back for our Advanced Open Water! We were welcomed with open arms, and the vibes were just super cool from start to finish. A huge, huge thank you to our instructor Lydia! She guided us through the two and a half days in such a calm, professional, and supportive way. She explained everything clearly and always stayed patient and composed. Even in situations that were challenging for us as students while learning new skills, she kept her calm and guided us through with confidence and reassurance. At the same time, we could always laugh together — she brought amazing fun energy while still making us feel completely safe. It was always a great time with her, both above and under water! Also a big thank you to Lukas for his constant good vibes and positive energy. And a special thanks to Mike for the incredible photos! He made everything feel so easy, allowing us to fully enjoy the dives while still capturing awesome underwater pictures. Such a perfect balance. Overall, we couldn’t have asked for a better experience. Five stars without a doubt — we would 100% recommend Goodtime to anyone looking for an unforgettable diving experience on Ko Tao. We’ll definitely be back for our Advanced Open Water! 🌊💙
