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.

ecoDiving

1 Day ecoDive Courses

As scuba divers, we have the unique ability to take direct action against the threats to the ocean environment like climate change, pollution, and marine species decline.

Whether you’re a holiday diver, student or professional, learning marine conservation skills can enable your contribution to projects all over the world actively saving our seas, and improve your fun diving experiences forever.

An advanced knowledge of coral, marine species, and the incredible interactions of the underwater ecosystem makes all future diving even more remarkable. 

ecoDives

Each of these ecoDives focus on a specific topic of marine conservation diving, covering an academic review and digging into skills and considerations of conservation diving.

You’ll join your instructor on two ecoDives practising these conservation techniques, building your understanding of the ecosystem and species interactions and participate in one of our ongoing projects, leaving a valuable contribution to the preservation of Koh Tao!

Space on our ecoDive programs is limited, so please get in touch to enquire about availability.

Intro to Marine Conservation

What is marine conservation and why is it necessary?

Learn all about tropical coral ecosystems and the species within, threats to the tropical marine environment and what specific marine conservation projects aim to do.

During your dives, you’ll 

  • Receive specialized buoyancy training – a necessity for conscious interaction with our reefs!
  • Learn how to use conservation tools and skills like knots, lift bags, survey techniques, and more.
  • Understand the different forms of substrate that make up reef ecosystems.
  • Participate in a monitoring survey to measure the substrate development of one of our artificial reefs. 

Divers completing these ecoDives build an awareness to see the reef in an entirely new way, adding new value to all future fun dives with an understanding of an individual dive site’s unique complexities!

Coral Ecology

We regularly hear the news reports about the state of coral reefs around the world. But why are coral reefs so  important, and what can we do to conserve their health?

This course introduces you to the basic biology and ecology of reef-building coral animals and their importance  to the entire ecosystem.

During your dives, you’ll

  • Learn how to identify coral growth forms, evidence of bleaching and disease
  • Be introduced to the concepts of coral reef restoration
  • Learn how to use our tools to detect coral bleaching contribute directly to our Coral Health Analysis project. 

Divers leave with the tools and training  to conduct easy analyses on your dives all over the world, contributing to our global partner CoralWatch, a citizen science program operated by the University of Queensland.

Creatures of the Muck!

Did you know coral reefs only cover .01% of the ocean? Even though we spend most of our time diving on these gorgeous underwater ecosystems, there is an entire world to explore just off the reef!

During your dives, you’llearn how to safely dive in off-reef muck environments, perfecting your finning and buoyancy for the best dive possible. You’ll explore  the interesting world of macrolife and off-reef ecosystemsand experience a world of species only seen by few divers on Koh Tao from tough-to-find nudibranchs to the iconic blue ring octopus, and any other surprises the muck delivers!

 

 

 

Reep Sweep

While many of our ecoTrust projects aim to protect and conserve our reef environment, the local ecosystem also faces threats that require active restoration.

Learn about the dangers of ghost nets in the seas, the complexity of the trophic chain, the importance of good fisheries management, and anthropogenic impacts.

We’ll also explore other threats to our reefs, including fouling corallivores like Drupella snails and Crown of Thorns Starfish, surveying for features like abunance, impact, and how to identify signs of outbreaks.

During your dives, you’ll

  • Practise identiying spredators on the reef, monitoring for abundance and biodiversity
  • Conduct a water quality analysis, building an understanding of reef chemistry
  • Participate in a net removal or reef clean
Artificial Reefs & Coral Restoration

Learn how our artificial reefs operate and help us transplant and grow new coral!

Learn about why coral transplantation and artificial reefs are necessary, the techniques currently in use around the world, and innovative strategies offering promise for the future of our reefs.

During your dives, you’ll

  • Learn about coral reproduction 
  • Identify coral threats and predators
  • Conduct a water quality analysis to measure the reef chemistry
  • Transplant your own coral fragment to our nursery
  • And help us work on our artificial reefs!
Chemistry of the Reef

These dives introduce you to the importance of water quality and how its changes visibly impacts the coral reef ecosystem and its species.

During your dives, you’ll learn about and practise identifying different visual indicators to good or declining reef health directly linked to the state of the water quality, and what factors contribute to these changes.

You’ll participate in a reef health survey, and collect water samples we’ll then test to explore the different elements that explain our survey results – like pH, salinity, nutrients, dissolved oxygen, and more!

Our water quality analysis results are submitted to our partner Innoceana, which monitors water quality changes all around the Gulf of Thailand. This citizen science program offers a ready-to-go toolkit for you to carry on your own water testing anywhere in the world on completion of training! Our staff can support an mentor any of your future efforts.

Advanced Fish ID

During your  scuba training, you may have been introduced to different species of marine life on the reef. Perfect your skills by learning how to identify fish and invertebrate species in tropical ecosystems by their visual markings, behaviours, symbiotic relationships, and ecological significance

During your dives, you’ll

  • Learn new species and how to identify them
  • Understand how to assess a reef’s health based on the abundance and biodiversity of indicator and keystone species
  • Contribute to our environmnetal monitoring program, helping us track the health of our natural and artificial reefs
UV Night Dive

The reefs are beautiful by day – but at night they come alive.

Traditional night dives offer us a peek into the incredible activity on the reef after sundown, but under the power of a UV torch we can experience marine fluorescence by night. Many species of coral and other marine life elicit incredible, glowing colours under this light – letting us observe the feeding coral tentacles in detail, and see the bright intracacies of eels, scorpionfish, crabs, and otherwise transluscent shrimps! 

During this dive, you’ll learn about coral feeding and anatomy and why certain creatures react to UV light in this phenomenal way. We’ll explore the reef and find hidden creatures often invisible or missed by traditional underwater lights, engaging in a truely other-worldly experience.

*Previous night dive experience is required.
