Whaleshark Code of Conduct

Encountering whalesharks is a privilege, and it’s crucial to approach these gentle giants with respect and caution. As responsible divers, adhering to proper scuba diver behavior is paramount to ensure the well-being of both the whalesharks and the marine environment.

  1. Maintain a Safe Distance: While it’s tempting to get up close to whalesharks, it’s essential to maintain a respectful distance to avoid causing stress or disturbance. Admire these magnificent creatures from a distance, allowing them to move freely in their natural habitat.
  2. Avoid Touching or Chasing: Refrain from touching or chasing whalesharks, as this can disrupt their behavior and cause unnecessary stress. Remember, we are visitors in their world, and it’s our responsibility to minimize our impact on their environment.

  3. Practice Buoyancy Control: Mastering buoyancy control is crucial when diving with whalesharks. Avoid sudden movements or erratic behavior that could startle these gentle giants. Maintain neutral buoyancy to glide effortlessly alongside them, minimizing disturbance.

  4. Respect Wildlife and Marine Life: Whalesharks are just one part of Koh Samui’s vibrant marine ecosystem. Take care to respect all marine life you encounter during your dives, avoiding touching or damaging coral reefs and other delicate organisms.

⚠️ What Not to Do ⚠️

  1. Do not feed whalesharks or any other marine life. Feeding disrupts their natural behavior and can lead to dependency on human interaction.
  2. Avoid using flash photography or excessive lighting, as this can startle or disorient whalesharks and other marine creatures.
  3. Do not attempt to ride or grab onto whalesharks. This behavior is not only dangerous but also harmful to the animals.


Diving with whalesharks in Koh Samui is a truly magical experience that every scuba enthusiast should embark on. By following proper scuba diver behavior and respecting these majestic creatures and their habitat, we can ensure that future generations can also marvel at their beauty.
