The underwater world along the rock wall at Lighthouse showcases Koh Tao's most diverse hard and soft corals, creating a stunning display between 5 and 14 meters deep. Toadstool soft corals, Barrel Sponges, Christmas Tree Worms, massive Mottled corals, and staghorn corals adorn the area, forming a lively ecosystem teeming with marine life. This includes hundreds of Damsel fish, Sergeant Majors, Weibels Butterflyfish, Lined Butterflyfish, Beaked Coral Fish, various colorful Parrotfish, Red Breasted Wrasse, and the One Spotted Snapper.

In the shallower waters (3 to 6 meters deep), a vast field of hard corals becomes a bustling hub for smaller coral fish and a regular dining spot for turtles. Occasionally, a visiting Black Tip Reef Shark may venture this far north on the island. Amidst the rock crevices, you'll find crabs, moray eels, and an array of shrimps, such as ghost shrimps and Durban dancing shrimps. Schools of mackerel and fusiliers, both large and small, swim around the rock formations, with king mackerels often spotted hunting in this lively underwater environment. Small schools of yellowtail barracudas add to the excitement.
