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.

Our Projects

Reef Monitoring Programs

Conducting underwater surveys used to identify and monitor reef biodiversity and factors associated with reef health. Surveys are conducted on reef substrates, corals, invertebrates, and reef fish species and use a variety of different methodologies.

These long-term monitoring projects that gather fundamental data on the reef are essential for informing effective conservation efforts in order to promote a diverse and abundant ecosystem.

Water Quality Analysis

Involves analysis of water quality samples collected from the reefs to monitor several abiotic parameters. Analysis is done through titrations and digital methods used to monitor; pH, temperature, turbidity, nitrate levels, phosphate levels, dissolved carbon dioxide content, and dissolved oxygen content.

Each abiotic factor has several interactions with the reef therefore long term monitoring of these is important for identifying any correlations with reef biodiversity and health.

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.
