MARINE
LIFE.
Sri Lanka sits in the tropical Indian Ocean, where reefs, rocky habitats and shipwrecks support an extraordinary variety of underwater life — from tiny macro subjects to large marine animals.
Look closer.
Big animals may get the attention, but much of Sri Lanka's underwater character is found in the details. Every habitat offers something different, and what you encounter changes with location, depth, conditions and season.
