Snorkeling at Phi Phi Islands, Krabi, Thailand

I was at the world famous Phi Phi Islands in the Andaman Sea around 48 km South-East to Phuket in the Karabi province of Thailand. The best part here was snorkeling in which we just jumped into the sea to explore the vast and majorly unexplored marine life underwater. Their we had a majestic view of the marine life existing inside the water which most of the people haven't seen it live ( apart of television shows).
The fauna which I saw there included Green turtle , puffer fish, yellow margin trigger fish, huge lines of sea oysters and coral reef, copper ban butterflyfish and the most frightening and mesmerizing was the tiny Box Jellyfish whose sting could be life taking though they don't often harm humans that's why it was pretty safe there. Obviously the whole fauna which I mentioned isn't visible in the photo. At last this whole experience was inshort WONDERFUL...
