Oceana CEO Andy Sharpless is counted among the notable ocean conservationists -- including Carl Safina, Sylvia Earle and Robert F. Kennedy, Jr. -- in SEA VOICES, a coffee table book by Duffy Healey and Elizabeth Laul Healey. The couple has been involved in saving the oceans for decades, and they recently posted an excerpt of the bookâ€™s interview with Andy on their website.
Hereâ€™s an excerpt from the Q&A about krill, a topic near and dear to Andyâ€™s heart.
Q. Krill is very important to the overall food chain of the ocean. Can you briefly explain what krill is, why itâ€™s so important, and what Oceana and others are doing to help protect krill?
A. Krill are small, shrimp-like crustaceans. There are 85 species of krill, and they are present in all of the worldâ€™s oceans, and are particularly abundant in the Southern Ocean. Krill have light emitting organs called â€˜photophoresâ€™ that make them glow in the dark; swarms of krill at night or in the dark ocean depths make impressive swirling light displays. The largest krill, the Antarctic krill, is thought to live up to 11 years old. Ocean wildlife eats between 150 and 300 million metric tons of krill each year.
