In response to requests from the scientific community, we are adding a new species to monitor on REEF surveys in the Tropical Western Atlantic (TWA) - Diadema antillarum, the Long-Spined Sea Urchin. In the early 1980s, a large die-off of Diadema occurred throughout the TWA. This has had a significant and long-lasting impact on coral reefs in the region because Diadema is (was) one of the primary grazers on Caribbean coral reefs (keeping rocks clear for baby corals to establish and keeping algae from overgrowing established corals). The disappearance of Diadema, coupled with overfishing of grazing fish species such as parrotfish and surgeonfish in some parts of the Caribbean along with other complicating factors, has resulted in many algae-dominated reefs. Despite 20+ years since the die-off, the once wide-spread and abundant species has failed to recover in most places in the Caribbean. There is a growing collective of researchers who are hoping to map the current distribution and abundance of Diadema. REEF will be assisting this effort by including Diadema in our TWA protocol. Surveyors will report whether they were actively looking for Diadema or not, and if they were, in what abundance category (S,F,M,A - same as for fish). We are currently working on the necessary training materials and additions to the database, and the new protocol will be in place soon.
Last year we shared an article about a new non-native fish, the Regal Demoiselle (Neopomacentrus cyanamos), showing up in the southwestern Gulf of Mexico. REEF surveyors in the Yucatan region of Mexico have since reported the species. And now a new publication co-authored by REEF staff Lad Akins documents that the species could become established and spread in the western Atlantic. The study incorporated a computer model to evaluate the the non-native species’ potential to impact native populations. On the basis of this work, it is foreseeable that the reefs presently harboring Regal Damselfish will likely see increased abundance of this damsel. Immediate attempts to eliminate the fish, therefore, should be focused in nearshore shallow waters spanning Veracruz to Frontera, Mexico. To find out more about this study, published last month in the journal Marine Biology, and to see a complete list of the 50+ scientific publications that have featured REEF data, visit www.REEF.org/db/publications.
The species is native to the Indo-Pacific and Red Sea. Similar in appearance to the native Brown Chromis, the Regal Damsel is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the fins and tail. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin.
If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.
To those who are in the know, St Vincent is considered the critter capital of the Caribbean. To those who watch fish, it is known that the rare is commonplace and that the fishwatching is unlike any other location in the Caribbean. REEF’s data from the June Field Survey supports those claims. With a team of 13 divers, the REEF group recorded an astounding 243 species, more than 65 of which were unlisted “write-ins” on the survey forms.
Diving with Bills Tewes at Dive St Vincent, long time REEF supporter and widely regarded “Caribbean Character”, the team split up on two boats and survey sites around the southwest end of the island. Long-time REEF expert Franklin Neal provided an extra special view from above and into shallow water as he snorkeled, while other team members spent hours on each dive exploring varied habitats and depths.
Special finds during the week would take an entire newsletter to list, but there were a few fish that stood out including the still undescribed Bluebar Jawfish on most sites, five frog fish on one dive, multiple black brotula, various pipefish commonly sighted and the largest spotfin gobies (10 inches?!) we’ve ever seen. The fish of the week may well have been the Golden Hamlet that Bill pointed out as his favorite fish and the species that adorns the cover of Reef Fish Identification.
The diving was bottom time unlimited and many dives exceeded two hours finishing in shallow water. Habitats were varied and visibility ranged from good to excellent on all of our dives. REEF is already planning our next Field Survey to dive St Vincent in August of 2008. The project will be led by Paul Humann and will be a must for any serious fishwatcher.

REEF recently completed our AAT monitoring of Biscayne National Park (BNP). Over the last two years, we have monitored fish assemblages inside the marine park at 6 separate locations twice each year (March and September) to correlate our results with historical data that BNP has collected. REEF’s future collaboration with BNP is yet to be determined but will likely involve assisting them with the potential establishment of a protected area somewhere within the Park’s boundaries. REEF is excited to have this opportunity to continue working with BNP this upcoming spring so please stay tuned for more information once our future project is defined.
Meanwhile, I would like to personally thank the monitoring team from our last event for their “above and beyond the call” efforts to get the job done. We had weather issues that delayed the project by a full week, followed by a tragic death in the Key Largo diving community in losing Mike Smith. All of us at REEF especially acknowledge Lad Akins for his efforts as our boat captain, Rob Bleser (owner of Quiescence Dive Shop where Mike worked) for pushing this project through under very difficult circumstances, and Steve Campbell for acting as boat captain on our last day. And thank you to the diving team for juggling your schedules to make sure we had enough divers each day: Jesse Armacost, Dave Grenda, Brian Hufford, Lillian Kenney, Mike Phelan, and Joyce Schulke. Everyone pulled together through the above challenges and I was proud to dive with each of you.
The REEF 2008 Field Survey Schedule is in full swing. Many of the trips are already sold out, but we wanted to bring your attention to one that still has some space on it -- the Field Survey to Baja Mexico aboard the Don Jose in the Sea of Cortez this October. This is a great trip, with spectacular diving and lots of tropical fishes, warm and clear water, and beautiful topside scenery. Some of the highlights include giant hawkfish, jawfish the size of your leg, whale sharks and manta rays, and spectacular sunsets over unpopulated desert islands. This will be the 5th time that REEF has done this amazing trip, and there is a good reason we keep going back. Come see what it's all about. The trip begins and ends in La Paz Mexico aboard the Don Jose live-aboard. Dr. Brice Semmens, reef fish ecologist and expert in Baja fishes, will be leading this trip.
This Field Survey is only held every few years so don't miss your chance! To find out more, check out the trip flyer. To secure your space, contact Jeanne at Baja Expeditions, 800-843-6967, firstname.lastname@example.org.
October 5 - 12, 2008 -- $1,550 - $1,750 per person, depending on room type. Package Includes: Six nights shipboard accommodations and one night local hotel accommodations in La Paz. Meals are included, beginning with breakfast on Day 2 and end with lunch on Day 7, and includes beer, soda and wine while shipboard.
In January, 2008 the National Aquarium Institute organized and conducted a Bahamian conservation expedition on the Aqua Cat live-aboard dive vessel. Our mission was to conduct REEF surveys and work on the invasive lionfish project. On board this trip were Lad Akins (REEF Special Projects Director), Ned and Anna DeLoach, Chris Flook (Bermuda Aquarium), National Aquarium staff, and aquarium and REEF volunteers. In addition to meeting the lionfish research goals of the cruise, we were treated to not one but two exciting and rare finds - the Exuma goby and the lemon goby.
At a dive site in Eleuthera called Cave Rock Reef we geared up and readied ourselves for lionfish behavior monitoring. Just as I started getting my gear together Anna came to the surface to tell me she had found a school of Exuma gobies, Gobiosoma atronasum. What I had not realized was that the keen eye of Bruce Purdy, owner of the Aqua Cat and avid REEF surveyor and supporter had noticed them at this site before and he had directed Anna to the exact coral head. I have logged over 400 dives in the Bahamas and until this day the Exuma goby had always eluded me. To the casual observer this fish looks like a cleaning goby or sharknose goby until you notice its behavior. Unlike most other “neon-type” gobies, the Exuma Goby spends most of its time hovering in the water column, not perched on the coral. They act very similar to the masked and glass gobies. Excited to add a new species to my life list I leave the small cluster of these great fish and head down to my assigned duty of monitoring a lionfish.
Two days later, while on a dive at Blacktip Wall in the Exumas, I noticed a few fish mixed in with school bass. These fish looked out of place and very different from anything I had ever seen. I noted as much detail as possible on my REEF slate and swam on hoping that one of my fellow trip members would be able to help me identify it. As it turns out no one had any idea what it was, but luckily Ned had also seen this odd fish and had taken some great photos of it. After some research when we returned from the trip, we discovered this fish was a lemon goby, Vomerogobius flavus. The lemon goby is an exciting new fish to the REEF database. This species was identified and described in 1971 from 11 Bahamian specimens, but this sighting in the Exumas is a range extension for the species.
It was truly a rewarding experience to finally see and survey the Exuma goby that I have searched for on many trips. To document a fish that I did not even know existed was the icing on the cake. For a fish lover like me, getting to find a new species for the REEF database is an honor. REEF surveying truly keeps diving exciting and new. I am concerned about the effects that the invasive lionfish could have on these two species of gobies with such a narrow range in which they live, but the data from all of our great volunteers helps us track these changes. It would be a shame to lose such unique endemic species due to this foreign invader. We hope you enjoy seeing some of the first photos ever published of these two goby gems.

REEF has been around for over 15 years and we felt it was time to give back to the community that has housed and supported us since REEF’s inception. So we came up with REEF Fish & Friends, a monthly meeting/seminar in Key Largo that gathers snorkelers, divers and armchair naturalists to learn more about fish and have some fun. Our first REEF Fish & Friends was held March 10 at the James E. Lockwood REEF Headquarters. Paul Humann, the opening night speaker, shared the history of REEF and highlighted milestones over the last decade and half.
Paul visited with guests and signed books and then spoke for about an hour. The room was packed and people were even standing in the hall to listen. As most of you know, Paul is the consummate story teller and we had some laughs, learned some new things about REEF and got to hear firsthand how the organization came to be.
REEF Fish & Friends will be held the second Tuesday of each month from 6:00 PM to 7:30 PM at the James E. Lockwood REEF Headquarters at MM 98.3 Key Largo. We invite everyone to stop in and share some food, drink, good conversation and hear a relevant topic about REEF’s projects or a mini fish ID seminar. We are planning a line-up of interesting guest speakers as well as REEF staff in the coming months.
In conjunction with the lecture series, we will also be working with local dive operators to arrange a monthly REEF survey dive/snorkel trip. No experience necessary. REEF Fish & Friends is all about learning how to survey and teaching others – its fun, easy and you will reap immediate results – making a dive that counts.
Upcoming Fish & Friends -- On Tuesday April 14, Lad Akins, REEF’s Director of Special Projects and the recognized lionfish expert, will present Born in the Wrong Sea – a presentation about the invasion of the Pacific lionfish in Atlantic and Caribbean waters. He will present the latest information on sightings and the important marine conservation work that REEF is doing to manage this huge environmental problem.
Tuesday May 12, Lad will return to present Parrotfish and Wrasse. This will be a shortened version of the presentations that are done on REEF Field Surveys. Even if you think you know your Parrotfish and Wrasse come and listen as Lad presents ID techniques, habitat and behavior. These hermaphrodites are fascinating and are sure to provide fodder for an interesting presentation.
Keep an eye on our REEF Fish and Friends webpage (www.reef.org/fishandfriends) as we post info about presentations, trips, photos and more. So see you Tuesday April 14 at the James E Lockwood REEF House, MM 98.3 from 6 PM to 7:30 PM.
Our t-shirt may say, “It’s all about the fish”, but if you’ve been on a REEF trip, you know it’s about the people too. Diving with like-minded enthusiasts who share your interest in learning more about our underwater world is one of the best ways to spend your dive vacation! Our recent trip to Curacao was no exception – a great group of surveyors of all levels came together to share their knowledge, fish encounters, and a lot of fun. Experts Doug Harder and Kay Tidemann showed us some of the unusuals, including the delicate Pale Cardinalfish and a rare reverse-pattern Goldentail Moray. We even taught our divemaster Elric about some of the various phases of wrasses and parrotfish. At the end of the week, our sister team of Helen and Sally Davies both passed their Level 3 tests, and beginning surveyors Amy Kramer and Norm Valor are now officially at Level 2.
If you are interested in taking a “dive (trip) that counts” and making new friends, there is no better way than to join us on a REEF trip next year. Our diverse schedule has something for everyone, and some trips are already starting to fill up…only a few spots are left on the Belize Lionfish trip for example.

REEF has been on the road this past month, and was well-represented at two prominent West coast dive shows – the Scuba Show held in Long Beach, CA, and the NW Dive and Travel Expo, in Tacoma, WA. Volunteers - composed of active surveyors and members of the Advanced Assessment Team in California, Oregon and Washington - helped staff the booths. Show-goers seemed to get a kick out of the ‘pop quiz’ (a few common local fish) they were given as they walked by the booth – demonstrating the fact that even if divers only know the ID of one fish, they can get started doing REEF surveys in the Volunteer Survey Project. “Friend of REEF” stickers were freely handed out and put on shirts.
While our main objective was to spread the word about REEF's programs, connect with current REEF supporters, and engage new volunteers, we also sold REEF gear – hats, books, slates, T-Shirts and the new Sensational Seas 2 DVD. Particularly popular were the new REEF water bottles. As always, these items are always available through REEF’s online store if you missed a chance to pick them up at the shows.
Special thanks to Heather George, Sasha Medlen, Matt Dowell, Gerald Winkel, Todd Cliff, Jeanne Luce, Georgia Arrow, Michael Johnstone, Carol McLagan, and Rhoda Green for helping with the booths. We couldn't do it without these REEF ambassadors. REEF also appreciates the support of the show organizers, including Kim and Dale Sheckler and Rick and Kathy Stratton.
