Glossodoris vespa Rudman, 1990
This dark gun-metal colored chromodorid is endemic to southern Queensland. It is one of hundreds of species to be included in Gary's i-Phone App (See Below). It cannot be confused with any other species due to its dark blue dorsum with bright yellow edge. Gary's photo above shows the brown sponge this species is commonly found on.
Those of you that have followed Gary's work know he is a careful observer. Presented here are some of his findings concerning the larval development of this species. Oh, did I forget to mention that G. vespa is direct development - the eggs hatch into a free crawling juveniles, and skip a planktonic larval stage completely?
The egg mass of G. vespa is a dorid type coil . A close look on day 27 shows the developing larvae tightly crowded within the ribbon.
Gary's drawing of the larval anatomy of a single developing specimen shows:
A - velar lobes
On day 29, the juvenile break out of the egg and crawl off in search of the brown sponge. Nice work Gary!

NUDIBRANCH ID iPHONE APP
A dedicated Nudibranch Identification Guide has been developed for the iPhone. Capitalizing on the popularity, ease of use and high-resolution touch screen of the iPhone, this innovative field guide does not require access to the carrier network or Internet.
The first in this series of iPhone Apps, with 700 species of Nudibranch (Sea Slug) from the Central Indo-Pacific Region where marine diversity is at its greatest are represented with stunning photographs sourced from 50 underwater photographers from around the globe, has already been released and has proven extremely popular.
Dedicated diver, underwater photographer and art director Gary Cobb of the Sunshine Coast, Queensland, Australia has devoted over 8 years to his passion for these amazingly diverse and alluring creatures.
I wanted to tackle the challenge of adding to our Nudibranch research and website by way of the new iPhone App technology but also expanding our finds to cover the entire World Gary said. In this way exceptional field guides are produced whereby the user can check off species and create their own lists. He and David Mullins dive up to 4 times a week, weather permitting, and have catalogued in their local area, 466 species. First I had to learn how to build with this new iPhone App technology, and then contact the photographers to request permission to use their images. The result was overwhelming. For people who appreciate these creatures the App couldn't come soon enough.
Photographers who have donated their images are acknowledged on the Info page and on all photos.
The second App in the series is under development and soon marine scientists, naturalists, students, divers and the world-wide community of Nudibranch enthusiasts will be able to view 426 species that live in the East Pacific region from Alaska to the tip of Chile.
Features of the East Pacific App:
1. Nudibranch Facts - Information about Nudibranchs, what they are and what makes them so interesting and unique in the underwater world.
2. Species - An alphabetical listing of 427 species of Nudibranch to be found in the East Pacific Region in a scrollable index that provides access to individual species pages containing a large photo and information about the selected species.
4. Images - The Images Gallery is a scrollable screen of Nudibranch thumbnails. They are presented 4 across the screen providing 24 "at a glance" images.
5. Search - Full search ability. The search capability of this App is both convenient and comprehensive. The search is species centric displaying a list of Species in response to the search input based upon any of Order, Family, Genus, Author, Date, Size, Color, Checked off species or even just a Species name.
6. Information - About the App and tips on how to get the most out it as well as tips on getting the best search and acknowledgments.
7. The ability to check (tick) off Species and to be able to email the List.
8. Navigation around the App is extremely fast, logical and intuitive.
The East Pacific App is a stand alone Application built for the Apple iPhone and does not require an Internet connection. It will be purchased for $8.99 from the iTunes App store when completed.
The photographers name will be placed on the Photo and name in the Contributing Photographers list of the Info view plus a Free App. The list of photos still needed is about 100. Nearly there. Lores photos are fine minimum size is 400x400 pixels. Photos must show the entire animal and be of good clarity. Also some screen shots to choose from.
East Pacific Species photos still needed:
Gary is currently working on Four (4) new Nudibranch ID Apps which together will cover the entire world. For more information see the Nudibranch ID App website at www.inudibranch.com
The 12 Annual San Diego UnderSea Film Exhibition is set for Friday and Saturday evenings, September 9 and 10, 2011 7:00 pm at Irwin M Jacobs' Qualcomm Hall. |
Thirty-two short underwater films, produced by leading professional and amateur videographers from around the world, will be highlighted at the 12 Annual San Diego UnderSea Film Exhibition in Irwin M Jacobs' Qualcomm Hall big screen auditorium!
Starting at 7:00 pm, each evening will feature 16 different films, most in high definition, limited to 5 minutes each of fast-paced action. A state-of-the-art digital projection system will bring the world beneath the surface to the eyes of the audience.
This exhibition is unique because there are no entry fees and no prizes, except for the prestige of having a film chosen. An independent panel of three distinguished judges will select the best films among many international entries.
Each year the bar is raised in terms of quality and excitement. From the kelp forests of California to the coral islands of Indonesia, from the sperm whales of the Caribbean to the mantas of the Maldives, there will be something for everybody.
Also shown for the first time will be the winner of Capture the World, an international video competition. Tickets are available for $15 per evening online at SDUFEX . SDUFEX is a 501c3 nonprofit organization.
A portion of the proceeds will go to Birch Aquarium , San Diego Coastkeeper, and the Chula Vista Nature Center. Previous shows have been sellouts, so get your tickets early. A limited number of tickets may be available at the gate.
