Free REEF Invertebrates and Algae Identification Class

taught by our own Power Scuba guru Herb Gruenhagen!

VERY IMPORTANT: Herb's classes are excellent and fun - and they generate big waiting lists. No-shows are not appreciated! You MUST commit to attending the class, and, if you find you can't make the class, you MUST change your RSVP in time for a wait-listed member to attend. If you think work or family situations might make you cancel at the last minute, DO NOT SIGN UP. Not showing up (and thereby depriving others of a chance to take the class) is neither considerate nor fair to your fellow divers.

NOTE: Attendance will be tracked. If you RSVP “YES” and you fail to attend without a timely cancellation or the excuse of a serious emergency, you won't be allowed to attend the next class.

Become a 'Citizen Scientist' and find out who's living in the neighborhood!

Ocean Enterprises, 7710 Balboa Ave, SD 92121 (small upstairs classroom)

COST:  You commit your attendance, time and effort. No money required.

Snorkelers and SCUBA divers, are you fond of squid and octopi? Do you want to know more about nudibranchs and tunicates? (Are you scratching your head and saying, "What the heck is a tunicate"?) Are you curious about the REEF Monitoring Project? Want to contribute to science by surveying our local marine life?

You can do all of the above by attending the San Diego Oceans Foundation's REEF identification training program. You'll learn a lot more about our local marine neighbors and how they live.

Whether you're a brand-new Open Water diver, an avid snorkeler, or an experienced diver wanting to expand your knowledge, this class will give you a ton of interesting facts about our underwater world...and it doesn't stop there! Once you've finished this fascinating course, you'll be able to perform REEF surveys and record your observations online. It's fun, it's easy, it's FREE - and best of all, REEF surveyors are constantly adding to a marine-life database used by scientists.

If you can't make this class, upcoming classes will be held the 3rd Wednesday of each month:
Fish ID classes (2014: July, Sept, Nov)
Invertebrates & Algae ID (August, Oct, Dec)

Four things you need to do:

1. If you've RSVP'd, please show up. If you must cancel, do it in time to give someone else your spot.

2. Be on time - there's a lot of material to cover in 3 hours. If you're late you'll miss some of the good stuff.

3. VERY IMPORTANT: By taking this class and registering at REEF's website, you automatically become a REEF Level 1 surveyor. To achieve Level 2, you must receive an 80% score on the end-of-class quiz. You'll need to know the common name and phylum of these invertebrates and algae (for instance, Sunflower Star/ Echinodermata). Your chances of achieving Level 2 are much better if you study beforehand. Please familiarize yourself with the material before you come to class. Here are a number of online study aids for you to use:

    I learned so much that besides studying all the animals before class, I took a whole page of notes during class. Herb taught me that with identifying cnidarians, think round and stinging. Uno (as in unochordata) means false, so false or non nodochord. Sponges have cellular recognition and much more! This was fun, interesting and quality education. Thanks Herb!

    Went much more in depth than I was expecting. Even reading the materials didn't seem to help me much, but I learned a lot of good things tonight.

    What you need to study is the 9 Phylum Names that go with what 64 common names.
    For example,

    Algae Bull Kelp
    Porifera Red Volcano Sponge

    The 9 Phylums are:

    Algae (plant-like)
    Porifera (hole-bearing sponges)
    Cnidaria (stinging nettles)
    Bryozoa (Moss Animals)
    Annelida (segmented worms)
    Mollusca (soft-foot)
    Arthropoda (jointed feet)
    Echinoderms (spiny-skin animals)
    Urochordata (sea squirts)

    have fun.

    Hey PowerSCUBA divers,
    I would like to echo Jonathan's comment on studying inverts before class next week. Please use my powerpoint presentation:

    1. Download:­

    2. Find on page: Invertebrate & Algal Identification
    Start at page 26. Yep, there are 64 inverts/algae species, and yep, you will be introduced to all 64 of my closest friends of the sea.

    best fishes,

    You absolutely need to study before the class to pass the test. Go to the below URL, select CAL REEF Invertebrate ID, and click Start Study Session. Then click Start Session. Use the Space Bar to flip cards and move between them.­
