Evening Lecture: Delving into the Lives of Clams by Dr. John DeMartini Thursday, Oct. 17th 7 p.m. - 8:15 p.m. Please arrive early for a good seat. Donations are appreciated.

John DeMartini has been involved with the Redwood Science Project for many years and has helped with coast naturalist training and other field work and educational outreach. He was a professor at HSU from 1963 - 2001 and his favorite class to teach was invertebrate zoology. During this lecture he will explain the form and function in the architecture of clams in both marine and freshwater species along the Pacific Coast. Major exemplars are the fat gaper clam, razor clam, sea mussel, and piddocks. Come and expand your world view of "clamminess".
