Species studied include:

•             Gray, Blue, Fin, Minke, Humpback and Orca whales

•             Common, Bottlenose, Risso's and Pacific Whitesided dolphins

•             California Sea Lions

To enroll, you must be at least 18 and an ACS-OC member.   If you're not yet a member, you can buy a student membership for $35, payable by separate check (made out to "ACS") at the first class meeting.​

ACS-OC conducts naturalist training once or twice a year.  The next class will start April 5 and run through June 14 (ten meetings), and as of this posting, there are some slots still available.  To express interest for this and future classes (no obligation), please email the instructor, Desi Green, at LGreen1128@aol.com. You can find out more about the April class by clicking here for the syllabus and enrollment instructions.


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.
