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.
We have one week left in our summer matching campaign, and want to thank everyone who has given so far. This summer, we are highlighting all the amazing discoveries made possible by generous donations from members like you!
To make a contribution, please visit www.REEF.org/donate.
According to the National Oceanic and Atmospheric Administration (NOAA), “To date, we have explored less than five percent of our oceans.” What does that mean for REEF and our members? It means that there is so much out there to discover! Every year, REEF members are finding new species, and REEF scientists are investigating the lifecycles and behaviors of critical marine species. We are constantly learning new things about ocean wildlife that contribute to their survival.
It also means that all these new discoveries can help regulatory agencies and policymakers to make more informed decisions on how to manage our fisheries. In cases like the threatened Nassau Grouper, seasonal protections during spawning seasons have been developed. In the case of invasive species, like lionfish, removal events are being encouraged because they have been proven effective at controlling lionfish populations.
Please take this opportunity to make a contribution this summer and help REEF continue to make these important discoveries that ultimately protect marine species around the world! Thank you again to all our members who support us in our mission, and have a great summer!
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 Jet Long. Jet lives in California, and has been a REEF member since 2013. He has participated in several REEF Field Survey Trips and has conducted over 50 surveys. Here’s what Jet had to say about REEF:
When and how did you first volunteer with REEF?
I first heard about REEF from fellow REEF member Hideko Kawabata during a volunteering trip. Doing fish surveys all over the world sounded like an interesting idea to me. I spent more time learning about REEF when I got home and decided to join. My first REEF trip was in 2013 to Southern Bahamas on Turks and Caicos Explorer II. I learned a lot about lionfishes (e.g. anatomy, how to hunt and cook them). Since then, I try to do at least one REEF fish survey trip every year.
If you have been on a REEF Field Survey, where and what was your trip highlight?
I have done a few REEF Field Surveys. The one I like the most so far is the Philippines Dumaguete Atlantis Resort trip. It might be because it was the first time I did muck diving. The fishes and creatures that you could find were amazing (e.g. many types of anemone fishes, bobtail squids, slingjaw wrasse, mantis shrimps). The highlight was no doubt swimming with the world’s largest fish – whale sharks!
What is your favorite part about being a REEF member?
There are a lot of good reasons why you want to be a REEF member. You can help to establish a fish database which is used by different research projects. You will visit places that you may not think of visiting. But the best part is the expansion of your knowledge on fishes, sea creatures, and the ocean when you are on a field survey trip. You will see the underwater world differently once you learn more about it. You will learn the importance of protecting our ocean.
What is your favorite place to dive?
I would have to say the Coral Triangle. Its high concentration of fishes, corals, and other species is really amazing.
What is the most fascinating fish encounter you’ve experienced?
When I was in Dumaguete Philippines, I saw two Black-saddled Tobies facing off with each other. At first, they were in the middle of the water column. They then spiraled down towards the bottom. They eventually glided through each other’s body. I didn’t expect this to happen.
What is your favorite fish or invertebrate?
Ocean’s giant gentle Manta Ray is my favorite fish. It was absolutely beautiful to watch them swimming and hovering the cleaning station.
Do you have any surveying, fish watching or identification tips for the REEF members?
Do more! The more you do, the better you will be in identifying the fishes in a particular region. Before each field trip, one should spend some time watching the Fishinars to get familiar with the fishes. In addition, a fish ID book is a really useful tool to learn about the fishes before and during the trip.
What is your most memorable fish find and why?
Seeing a Crocodile Flathead hiding in the sea grass during the Palau trip was really neat. Its camouflage body made it almost impossible to locate. I was just lucky to look at that specific patch of sea grass. The fish that I really want to sea underwater is Ocean Sunfish (aka Mola Mola), which is supposed to be the world’s heaviest bony fish.
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.

Six volunteer divers from the REEF Advanced Assessment Team (AAT) surveyed two sites off the Aquarius Reef Base in Key Largo, Florida, to assist the National Marine Sanctuaries Program (NMSP) with the science component of the Aquarius 2007 Mission: If Reefs Could Talk. Aquarius, the world's only undersea laboratory, is part of NOAA's National Undersea Research Program (NURP) and sits seven miles off shore at Conch Reef. A valuable resource and good neighbor to REEF HQ, Aquarius hosts scientists from around the world, from sponge chemists to astronauts, in innovative research and education.
The team included REEF Special Projects Manager Lad Akins and AAT members Dave Grenda, Brian Hufford, Lillian Kenney, Wayne Manning, and Mike Phelan. Twelve fish surveys were conducted at each of two research sites near Aquarius using the Roving Diver Technique (RDT). This year's data will be compared to surveys collected during a 2001 mission to assess change in resident fish populations. The team also assisted NMSP in documenting the occurrence of long-spined sea urchin (Diadema) at each site. Once abundant on Florida Keys coral reefs, herbivorous Diadema play an important role in keeping coral-stifling algae from overtaking the reef structure.

On Saturday, February 9, REEF will host an ocean-themed dinner and auction at Amy Slate’s Amoray Dive Resort to raise awareness about REEF in the Florida Keys community and help conserve local coral reef ecosystems. Underwater photographers Paul Humann and Ned DeLoach will present new images of sea life taken on their worldwide dive travels. A silent and live auction will offer prizes from local businesses and travel to destinations including Bonaire and Papua New Guinea. Tickets are $75 each and include buffet dinner, open bar and dancing.
For more information, including how to purchase tickets, become an event sponsor or donate auction items, please visit www.REEF.org/loveofthesea. If you are in the area, please join REEF for this unique opportunity to celebrate the Valentines season and kick off 2008 as the International Year of the Reef.
Once again, it is that time of year when many of you are getting out on the water and conducting REEF Fish Surveys. I have put together a few bullet points based on my experiences surveying with members and answering questions on techniques and things to watch out for when filling out your data sheets. Here are a few tips:
- REEF Hats! Just Added to the REEF Store. Check them out and get yours today.
- The 2009 Field Survey Schedule has been updated with several new trips, including a second trip to Cozumel this December and Bermuda with Ned and Anna DeLoach in October 2009.
- REEF researchers and collaborators have been busy in the field this month on the Grouper Moon Project. Watch for an update in next month's REEF-in-Brief.
- REEF's Lionfish Research was featured on the National Geographic News earlier this week. This follows extensive coverage by the Associated Press earlier this month. Also this month, Anna DeLoach produced this 5 minute video for Scuba Diving Magazine that looks at the the recent lionfish population explosion, the reasons lionfish are the perfect invader, how they got to the wrong sea, what REEF is doing about it, and how divers can help. Watch this informative video here. Read more about this project in this recent press release.
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.
