The MLML Museum is home to an herbarium collection of marine macrophyte (algae and plant) pressings, and many specimens of invertebrates, fishes, turtles, birds and mammals. Much of this is in preservatives in jars, but there is also a fairly vast collection of dried specimens, bones, skins, and stuffed organism. This is a unique collection focusing on the biota of the Monterey Bay, collected over the last 50 years. Now called the Marine Biological Collection (MBC), it represents a thorough sampling of the flora and fauna of Monterey Bay and the larger sub-tropical and temperate Northeast Pacific region (Baja California, California, Oregon and Washington). It has proven to be a valuable research and teaching tool. This history, compiled by MLML Emeritus Professor of Ichthyology, Gregor M. Caillet, is in draft form.
