spermwhale

Underwater photographer Keri Wilk was swimming with sperm whales off the coast of Dominica in March 2014 when found he found himself capturing something rather unexpected: a massive whale "defecation event."

Last month, photographer Shawn Heinrichs spent 9 days at sea off the coast of Sri Lanka in search of blue whales. Although the trip ended without any photographs of blue whales, Heinrichs and his team did manage to capture a world's first: photographs of an epic battle between killer whales and sperm whales.
