Leopard shark - Bida Nok - Dive The World ThailandOn the South facing side is a large sheltered bay where you can spot Black Tip reef sharks cruising in the shallow waters and maybe even octopus if you are lucky! Swim south out of the bay and look for blue spotted sting rays, flounders and cuttlefish in the sandy flat bottom. The beautiful Finger Reef is fantastic, covered with huge gorgonian sea fans, whip corals and bubble coral. Finger reef drops off down to 20 metres south west of the bay and this is where the most beautiful coral and rock formations can be found. It’s also the best area for seeing banded sea snakes and hawksbill turtles. The wall descends straight into the sea and is covered with soft corals and vibrantly coloured anemones. Look closely into the crevices for all types of moray eels and lionfish. Between the months of October and April look out for the rarer species like ghost pipefish hidden in the many sea fans.
Huge pinnacles teaming with life are covered with soft and hard corals, cleaning stations with a variety of cleaner shrimps wait patiently to work on morays and groupers who may stop by. Caverns and overhangs are aplenty on the deep side and look out to the blue to see schooling Trevelley and jacks swooping in to feed off the reef. The deep and shallow sides both boast a healthy supply of bearded scorpionfish, cleaner wrasse, moorish idols, parrotfish, anemone fish, butterfly fish, angel fish and honeycomb grouper. Swim through the schooling masses of yellow snappers and gaze up to the surface to see crocodile needle fish prey on the periphery of sardine schools.
Leopard sharks may be spotted resting in the sand and although not regular visitors, whale sharks and mantas have been seen here by some lucky divers every year.
As you ascend up along the shallow reefs, look out for black tip sharks and enjoy the beauty of this reef all the way to the top where you surface next to the stunning lime stone wall and await your boat to pick you up.
