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.

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

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.
