About Blennies:  Blennies are small, elongate fish, known to most fishwatchers by the species found in tropical seas. Worldwide there are about 900 acknowledged species. A typical blenny has a blunt head, long anal fins and fleshy, often branching appendages on their heads, known as cirri. They perch on rocks, reef or sand and dart quickly around their home territories. There are many other blennies that don’t fit this “typical” description, including a large group in the Indo-Pacific known as fangblennies or sabretooth blennies that spend much of their day swimming in the water column. See more about blennies.

About the Blog:  The Blenny is our poster fish but we love all fish and critters. Here, we blog about whatever strikes the BlennyWatcher’s fancy  – Fishwatching, SCUBA Diving, Underwater Video, Travel  – our topics are happily all over the place. Our specialty is observing marine life behavior so we’ll emphasize that and even pull a few golden oldies from the vaults. We have stopped posting to our other blog, MarineLifeBlog, but the old posts, where we chronicled our travels and featured the images of the wonderful creatures encountered underwater on those trips, are still up. Anna also has a blog about the topside bugs and blossoms she encounters:  PondPeeps

About the BlennyWatcher and Anna & Ned DeLoach:  The BlennyWatcher is the nom de plume for Anna DeLoach, a computer scientist-turned-underwater naturalist and researcher. Ned DeLoach is co-author with Paul Humann, of ten marine life field guides, including the award winning Reef Fish Identification, Florida, Caribbean, Bahamas. Anna and Ned currently write a marine wildlife behavior column for Alert Diver magazine. They also write a regular column, Critter Hunt, for Scuba Diving magazine and contribute to Sport Diver magazine. For the past seven years, they have been the resident naturalists at Buddy Dive in Bonaire, where they spend the month of September teaching fish identification and presenting programs about marine life behavior. They began conducting a similar program in 2010 at Eco-Divers Lembeh, in Indonesia. Read their full bios at their company website, New World Publications.

    Hello Anna,

    by coincidence, I just stumbled across this page.
    “Blenni” is my nickname; I did my Ph.D. on them.

    Please mail me your email address and I will send you some blenny stuff that might be of interest to you.

    • Mr. Wirtz,

      I am very interested in Blennies too. We just spent a week in Bonaire at Buddy Dive with Ned and Anna. I’m an electrical engineer turned marine life enthusiast. Anything you’d like to share I’d appreciate. We have a dive shop and club – and I try hard to educate our divers about interesting things that help them slow down and appreciate what there is to see out there.

      Thank you,

    Guess you missed Blenny Appreciation Day on Maui last year. When you can’t snorkel, it’s tide pools all the way.

    BTW, Survivor Blenny was a “gripping” tale. Loved it!

    Yours in snorkeling, Syd

    I recently dove Utila and came across something that no one has been able to identify. Can I send you the pictures?

    And, will you and Ned be at Dive Buddies in Sept 2013? I think my dive buddy and I would really enjoy the event.



  • Hi Anna!!!!
    I was so excited to find out about your EXCELLENT blog through Reef’s facebook post. I have been immersing myself in all of your wonderful writings, pictures, and videos. I am so glad you have done this!

    Anna, we loved seeing you once again in Bonaire and all the information you shared and suggestions for what to notice during out dives. I asked you if you knew how the fish name puddingwife came to be and you thought you might be able to find out once you were home. I have not found much on the internet so I hope you have. Thanks so much, Tiny Bubbles

    • Yes, it was fun seeing you in Bonaire. We’ll get started on the mystery of the origin of the Puddingwife name – I haven’t been able to find anything yet, but making inquiries. ~ Anna
