Whale sharks are the biggest fish in the sea! The largest reported individual weighed in at a staggering 21.5 tons and 12.6 meters in length. In a healthy environment, they’re also known to live up to 100 years old.

Did you know?

There are more than 3,000 different species of nudibranchs, many barely visible to the human eye! Some species can even store the venom from their food – like toxic sponges and hydroids – to use as a defense mechanism against predators.

Did you know?

Coral polyps are actually animals that can reproduce in two different ways. Because of its asexual capability, naturally broken fragments can be attached to artificial reefs to nurse the colony back to life, or create an entire new habitat altogether!

Did you know?

Butterfly fish are actually masters of camoflauge! Their markings mask their eyes, and several species have dots on their tails to confuse eager predators.

Did you know?

Ghost nets are one of the greatest physical threats to marine life. Every year, thousands of sharks, whales, dophins, and more are entangled in these abandoned or lost nets. When they drift onto our bays and pinnacles in Koh Tao, our ecoTrust team removes them as soon as possible to mitigate risk to our wildlife and coral.

Environmental Monitoring

Tyrone (Ty) is an Australian born waterman. He grew up on the beaches of Sydney and experienced diving at a premier dive school back when he was just 13.

From an early age Ty found a love for the underwater world and he never wanted to do anything other share this love. His diving career started in Sydney where he gained valuable knowledge and has been spending His time in Asia for the last few years fine tuning his skills, this is a dive instructor that balances dive life with a healthy social life. Easy going, patient and approachableā€¦ Diving is his passion, fun is his life.Ty2

Water Quality Analysis

Weekly, we measure metrics like temperature, salinity, pH, turbidity, nutrients, and dissolved oxygen in the water of our dive sites. This data enables is submitted to an island-wide database that helps to track changes over time and guide conservation efforts.

Coral Bleaching Surveys

Our team’s work supports CoralWatch, a citizen science program operated by the University of Queensland. 

Using a colour-based coral health chart, divers and snorkelers can evaluate the health of corals across reefs, adding the information collected to this global database that maps the extent of coral bleaching and gives scientists incredibly valuable information about recovery trends, disease patterns, and an accurate depiction of areas most threatened by coral bleaching. 

Debris Free Friday!

Come join our team each Friday at 5:45PM at Victor’s bar – right down on the beach from Roctopus HQ – for a sunset beach clean and free beer courtesy of RAID International!

All rubbish collected is recorded by our ecoTrust team and submitted to the Ocean Conservancy, which monitors global marine pollution.

Ghost Net Removal

Ghost nets are one of the most dangerous physical threats to our reefs. Abandoned or lost at sea, these fishing nets drift onto the reefs and pinnacles, smothering marine life and coral.

Our team monitors for ghost nets and other marine pollution, and sends dive teams out to recover these physical threats as quickly as possible.
