Adam Pack will present "Size Matters to Humpback Whales" at 6 p.m. Feb. 28 at the Hawaiian Islands Humpback Whale National Marine Sanctuary's site at 726 S. Kihei Road.
Pack, a University of Hawaii-Hilo associate professor, has been studying the role that body size plays in the mating game and social interactions of the humpback whale.
Using a novel underwater video-measuring technique, as well as deployments of National Geographic cameras, it has been shown that for humpbacks, the size of the animal plays a role when it comes to male-male competition, female and male associations, and the production of calves.
Pack's talk is part of the Sanctuary Lecture Series, free lectures focusing on humpback whales during this whale season. For more information, call 879-2818.
