Sperm whales, Sri Lanka Weeks of being out on the ocean searching for whales, rough waters, storms and a ton of patience. All necessary for these special moments. I first heard the Sperm whale before ever seeing them. A unique clicking sound used to communicate and hunt, they have the loudest animal caused noise in the world. Their click is so loud it can even stun prey. One of many beautiful moments during my time exploring the Indian Ocean with @alexsharks_ Thank you for the amazing footage @alexsharks_ always capturing the most epic moments #spermwhale #srilanka #ocean #indianocean #oceanexploration #whales #whale #adventure #freedive #freediving #exploration
