Robert Cerrato, Stony Brook University: Clams grow by adding tiny amounts of new material to the entire inner surface of the shell and they also extend the edge a little. So as a clam grows, the shell gets thicker and bigger. This growth process does not happen evenly or even all the time, but the amount of shell added depends on the conditions around the clam, especially the tides, the temperature, and the amount of food available. Meet with Professor Robert Cerrato and learn how clams grow, what influences growth and why it is important to determine their age.
