Did you know...

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?

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.

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?

Sea turtles each have a unique pattern of facial scutes – or scales – that enables conservationists to monitor and track populations. Wildlife Monitoring Programs like the Koh Tao Turtle Program help preserve local populations and mitigate threats.

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.
