BOOTHBAY HARBOR — Scott Kraus, vice president for research at the New England Aquarium in Boston, Mass., will be the guest scientist at Bigelow Laboratory’s Café Scientifique gathering at 6 p.m. Tuesday at the Opera House, 86 Townsend Ave.

Kraus will lead a discussion titled “Underwater Vision: What Do Whales See?” and share new findings about the unique characteristics that help whales deal with poor light and visibility underwater.

According to a news release, “Whales’ eyes have adapted to work throughout the wide variety of seascapes they encounter — from deep underwater to above its surface. We suspect that whales’ vision is a critical mode of sensory perception for prey detection and navigation, but remarkably little is known about what happens when whales encounter other whales, obstacles, ropes, or boats.”

Café Scientifique gatherings are informal discussions about scientific issues and society, current research, and the latest news from the field. They are free and open to the public with beverages available for purchase.
