As part of the Grouper Moon Project, REEF launched the Baby Grouper Adrift! webpage in late February. We developed this outreach tool to display in real time the results of state-of-the-art satellite drifter research being conducted by researchers from REEF, the Cayman Island Department of Environment, and Oregon State University. The Adrift project aims to better understand where Nassau grouper larvae end up after being spawned. Webpage visitors can follow the current drifters in real time as they complete a 45-day ocean journey (the amount of time Nassau grouper larvae spend floating in the currents), and even take a guess where the drifters will end up. It's been about 35 days since the drifters were released. Check out where those drifters are now -- visit the webpage at http://www.REEF.org/programs/grouper_moon/adrift. Funding for the Baby Grouper Adrift project was provided by the Disney Wildlife Conservation Fund.
When you call the REEF office, you may be greeted with a new voice. Please join us in welcoming Martha Klitzkie as the new General Manager. After completing a Bachelor of Arts from Warren Wilson College, a passion for marine education led her to serve as the Education Director at the Pigeon Key Foundation in Marathon, Florida. She later went on to direct a larger marine education program based at Camp Ocean Pines, located on the central coast of California. During this time she also completed a Master of Arts in Educational Leadership and Administration from Argosy University. But a love for the Florida Keys and its coral reefs brought her back home to the sunshine state to join the REEF team. As the General Manager, Martha supervises a variety of activities necessary to the day-to-day operations at REEF. Welcome, Martha!
There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems. REEF Director of Special Projects, Lad Akins, is a co-author on a recently published paper evaluating these effects. The study was published in the scientific journal, PLoS ONE. Lead author, Stephanie Green, from Simon Fraser University (SFU), along with Akins and other co-authors Aleks Maljković (SFU), and Isabelle Côté (SFU), documented a dramatic 65% decline in 42 species of reef fish eaten by lionfish over a two year period. The study, conducted off New Providence Island in the Bahamas, used data collected during REEF's volunteer lionfish projects to track the explosion of the lionfish population over time, and reveals that lionfish biomass increased from 23% to nearly 40% of the predator biomass on the study sites between 2008 and 2010. This study represents the first documented direct impact of lionfish predation on native reef fishes and highlights the importance of control programs to minimize impacts. You can find a link to this and all published papers that have included REEF data on our Publications page.
New research using powerful genetic techniques and the REEF survey data have revealed two new species of hamlet in the Caribbean. The findings were recently published by scientist Ben Victor in the Journal of the Ocean Science Foundation. As our Caribbean surveyors know, hamlets are a group of colorful small sea basses that can sometimes cause ID confusion because of their myriad of colors and patterns. The varied color patterns in these small predators are thought to be a result of mimicry of other colorful but more innocuous herbivore species. There has been ongoing debate about which are actual species and which are simply just color variants or morphotypes. Ben's research revealed significant genetic differences among what seemed to simply be variations of the well-known Barred Hamlet. Ben stated that "the REEF database supplied valuable survey data indispensable to understanding ranges and abundances and unmatched in its comprehensive coverage".
The two new species are the Florida Barred Hamlet, Hypoplectrus floridae, and the Contoy Hamlet, H. ecosur. The typical Barred Hamlet (H. puella) that is found throughout the Caribbean will be updated in the REEF database to be called the Caribbean Barred Hamlet. Florida Barred Hamlet have been found in the eastern Gulf of Mexico and South Florida, and overlaps in range with the Caribbean Barred Hamlet in those areas. To date, the Contoy Hamlet has only been documented on Isla Contoy near the northern tip of the Yucatan peninsula and maybe Isla Mujeres. Florida Barred Hamlet are distinguished by a pair of symmetrical dark spots at the base of the caudal fin along with a break in the mid-body narrow bar. The Contoy Hamlet is distinguished by the same paid of dark spots at the base of the tail as well as a series of additional dark spots along the upper caudal peduncle and below the dorsal fin. A PDF of Ben's paper can be found online here, and it includes many pictures of the new species. Video of the Contoy Hamlet has been posted on Youtube.
REEF surveyors in the regions of the new species are encouraged to learn the differences and being reporting them as distinct species using the Unlisted Species section of the online data form.

REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Joe Gaydos, Ph.D., an avid REEF volunteer in Washington State and Director of the SeaDoc Society (a REEF Field Station). Joe has been a REEF member since 2003 and has conducted 120 surveys. He is a member of the PAC Advanced Assessment Team, and Joe was instrumental in initiating the AAT San Juan Islands Annual REEF Monitoring Project that kicked off this summer (see story in this enews issue). Here's what Joe had to say about REEF:
How are you involved as a REEF member?
I conducted my first REEF survey in Washington State in 2003, and have been doing them ever since. In addition, the program I run, the SeaDoc Society, is a REEF Field Station. We’ve hosted numerous fish and invertebrate identification classes and multiple Great Annual Fish Count dives, but I’m most excited about our new monitoring program collaboration. We’ve partnered with REEF to have Advanced Assessment Team Divers come to the San Juan Islands for annual week-long survey trips. We expect that over the next 8-10 years these data will help us understand long-term sub-tidal changes in the ecosystem.
What inspires you to complete REEF surveys? What is the most interesting thing you’ve learned doing a REEF fish survey?
I live and dive in the Salish Sea, a 17,000 square kilometer inland sea shared by Washington and British Columbia. The data collected by REEF volunteers are valuable to the managers in the region who are working to recovery declining species like Northern Abalone and Rockfish. I love being able to collect data that is meaningful.
In your opinion, what is the most important aspect of REEF’s projects and programs?
As a scientist, I love that the REEF data are collected in a way that is scientifically rigorous. Volunteers are trained and their level reflects their training and experience. Also, it is great that the data are collected and stored in a way that they will always be available for evaluation – even decades from now. This is citizen-science at its finest.
Where is your favorite place to dive?
My favorite place to dive is about 2 miles from my house. It’s a high current area split by an island so you get the benefits of seeing all of the invertebrates that flourish in the current, but you can always dive on one side of the island or the other. The site is familiar, but strikingly beautiful and I always find something new. The water is cold here and people generally expect everything to be dull and they are amazed to see videos or stills of colorful invertebrates and fishes.
Is there a fish (or marine invertebrate) you haven’t seen yet diving, but would like to?
Here, most everybody wants to see a Giant Pacific Octopus – 150 lbs, 2,240 suckers (unless it’s a male, then they only have 2,060) – what’s not to love. But me, I still want to see a Pacific Spiny Lumpsucker. They’re only the size of a golf ball, but dang are they cute. When is Disney going to make a movie starring one of them?! Maybe this year.
REEF is excited to announce that we have added a new invertebrate and algae survey program to the Northeast region (Virginia - Newfoundland). Similar to our other temperate regions, REEF surveyors in this area can now record all fishes as well as a select group of 60 invertebrate and algae species. Species included in the program were selected in consultation with regional scientists and experts to serve as a representative sample of the biodiversity of the region. Consideration was given to species that are habitat indicators, are harvested, and those that are just fun to look at (like nudibranchs!). REEF Outreach Coordinator, Janna Nichols, launched the new program at the Boston Sea Rovers meeting last month. As part of the new program, we have created a new underwater survey paper that includes the invertebrates and algae, as well as a waterproof color ID card. New training curricula are currently being developed for Northeast Fishes and Northeast Invertebrates and Algae. All of the new materials can be found on the REEF online store. A big thanks to all who helped shaped this program, provided guidance, and donated images for the new materials.

Here's an excerpt from a recent review from a fellow REEF member:
"Doing surveys is a lot of fun and knowing what I am looking at has helped hold my interest in my SCUBA diving generally. The educational component is exceptional and I would add that the people that work for REEF are simply amazing and dedicated individuals who really demonstrate they want what is best for the members and the critters we encounter. I'm glad to be associated with such a fine organization!" Thanks Keith!
Funded by a grant through the US Fish and Wildlife Service, REEF’s Lionfish Program Coordinator, Elizabeth Underwood, will travel to cities throughout the Southeast United States to conduct a series of lionfish collecting and handling workshops. These workshops are meant to educate and engage stakeholders (recreational divers, professional divers, environmental groups, students, general public, etc.). Workshop topics will include background of the invasion, lionfish biology, ecological impacts, recent research findings, collecting tools and techniques, market development and ways to get involved. Workshops are free of charge and open to the public, however registration is required. To register or learn more visit www.REEF.org/lionfish/workshops. We hope to see you there! Scheduled workshops include: May 6th—New Orleans, LA; May 7th—Ocean Springs, MS; May 8th—Panama City, FL; May 11th—Pensacola, FL; May 12th—Mobile, AL; May 14th—Tallahassee, FL; May 26th—Morehead City, NC; May 28th—Durham, NC; June 4th—Jupiter, FL; June 8th—Charleston, SC; June 10th—Savannah, GA; June 18th—Orlando, FL; June 23rd—Naples, FL.
Itziar Aretxaga, a long-time REEF surveyor who lives in Veracruz Mexico recently sent in this rare fish sighting report about finding a Swordtail Jawfish. What a great sighting! Here's Itziar's story:
"Earlier this year, I was taking part on an underwater photography competition in Veracruz, Mexico. Every year the diving operators and other supporting organizations launch it as a way to draw awareness upon the diversity and richness of the protected National Park of Veracruz. I had no hope of winning anything as I am a novice photographer with a very basic camera and no illumination, but I wanted to support their efforts. Each of us had a 90-minute time limit to take up to 100 photos.
I saw this jawfish on the sandy area immediately below the buoy in Cabomex, Anegada de Adentro, at about 14m depth. I knew it was not any of the jawfishes I had reported before: face markings, behavior, and burrow type gave it away as a different species. I was set on identifying it more than on making any impression on the competition jury, so I spent my allotted 90 minutes by the jawfish, as motionless as possible, and trying to make it get used to the camera just 15cm away from its burrow. The series of photographs allowed me to identify it as a Swordtail Jawfish (Lonchopisthus micrognathus) based on the body bars and the pointy protruding tail, as described in the sketches of the ReefNet Fish Identification DVD. In looking at the REEF database later, I realized it is extremely uncommon to see this species. So all in all, I felt I had won a big prize in that competition!"
