Did you know fish have ears? And the ear bone is called an odalith and is used to age a fish just like rings on a tree? This ismerely one fascinating thing you will learn during a visit to the Rutgers University Marine Field Station during its open house on Saturday, Sept. 14, from 10 a.m. to 3 p.m.

As a rule, the field station is off limits to visitors because the scientists there are busy and can’t accommodate breaks in their routines.
