The Spring 2019 graduating class!

ACS-OC conducts naturalist training once or twice a year.  The next class will be in Fall 2019.   To express interest for this and future classes (no obligation), please email the secretary, Hannah Rich, at

This is a great chance to learn more about whales and dolphins!  Once you’re certified, you can represent ACS-OC on board whale-watching vessels, at schools and at other venues.

Some of our Naturalists have science backgrounds, but most do not. To be certified, you'll need a sincere interest in the subject, an aptitude for learning, good interpersonal/communication skills, and a willingness to devote time to learning more about these beautiful animals and how to teach people about them.

Naturalist candidates are expected to attend at least 10 sessions, make short presentations in front of the group on all species studied, and pass a 2-page written quiz.
