When they're hunting herring, humpback whales cooperate in groups of up to 20. One creates a cylindrical curtain of bubbles around the herring to prevent their escape while the others make sounds to confuse them and drive them to the surface, according to a National Geographic description.
Social intelligence among humpback whales is a topic of primary interest to Fred Sharpe, the executive director and principal investigator of the Alaska Whale Foundation and an award-winning naturalist.
At 6 p.m. Tuesday, Jan. 12, Mr. Sharpe will present "Humpback Whales: Team Hunting & Social Intelligence" at the headquarters of SRI Menlo Park in the International Building at Middlefield Road and Ringwood Ave.

The event includes a drawing for a $30 gift certificate for Kepler's Books at 1010 El Camino Real in Menlo Park. Kepler's adds the names of drawing participants to its mailing list.
