One of the most rewarding and fun aspects of being a REEF surveyor is finding a new species to add to your "Life List" (a lifetime compilation of all fish species seen). Even the most experienced surveyors, after hundreds of surveys, occasionally add new species to this list. Expert Caribbean surveyor, Patti Chandler, recently emailed us about one such find. Despite having over 900 REEF surveys under her (weight) belt, she and her husband Scott recently came across a little mystery while diving in front of CocoView Resort on Roatan - a brilliant blenny with BIG cirri on its head. After emailing the photo to a few experts, they discovered that they had captured what is likely the first in situ photos of the species, and also documented the first record of the species in the Western Caribbean. Not only does their sighting of a Horned Blenny (Paraclinus grandicomis) represent a "lifer" for their lists, it was also a new record for the TWA REEF database. Great find, Patti and Scott!

"Did you ever have a fish experience that both excited and sadden you?"
That feeling recently happened to me at the dive site Kalli's Korner in Bonaire. My husband, Chile, and I were having a great day of diving with our friends Bryan and Phyllis McCauley in their boat, Pufferfish. Towards the end of our second dive that day, I noticed a pair of eyes peeping out of some coral rubble. As I watched suddenly a small eel darted out and raced few feet before hiding again. I was immediately intrigued and, using my rattle, got my buddy Phyllis' attention. Pointing out the location, we watched as once again the little conger eel slipped out of his cover and moved away. We slowly began to approach in hope of a better look. The process continued as we sought to identify him and he continued his trek. Each time we were able to get a bit closer and look for characteristics. Finally he seem comfortable enough to look at us, as we looked at him. Suddenly, a barred hamlet appeared above him and scooped him up. Imagine our shock and horror!!! Anger raced through my body and instinctually I reached for my dive knife and took off after that (blank blank) hamlet. The chase continued as the hamlet, with his full tummy, eluded me and viewed me as if to say 'why are you after me?' What was my plan I thought later? Well, I only know if I had caught the sucker, oops fish, he would have been disemboweled in the search for the little conger eel. The sound of laughter underwater reaches me. By this time, my dive buddy is in stitches as I sheepishly return. Later research found a margaintail conger that matched our descriptions.
Now as I continue my search for what I hope are his companions, I will be keeping a wary eye out for hamlets in the surrounding area. So that’s my fish tale and now for the question: Should you report to REEF a fish, found, identified but not longer living in the underwater world?
You can bet I did.
A few reminders to our surveyors:
A couple of months ago, REEF launched our new website. Along with the new website, REEF launched some new membership Discussion Forums that will become more valuable as the survey season ramps up this spring/summer. There are 3 forums: ID Central for posting mystery fish and invert pics for other members to help identify and to post interesting fish behavioral observations; Trip Reports, where members can post trip reports for Field Surveys, Exotic Species, AAT, and any REEF or other group efforts; and the General Discussion forum where you can post stories and links about marine conservation concerns, ideas for REEF programs, and myriad other things. These forums are for our 35,000+ members to interact and create a synergistic connection around our conservation diving and snorkel efforts worldwide. Below is a post from long-time member, Todd Fulks, who recently witnessed Hairy Blenny (Labrisomus nuchipinnis) courtship/mating and took a really great picture of the mating pair. I have pasted it here so you can get an example of what could be posted in the ID Central Forum. To post to the forums you have to be a registered REEF.org website user which you can do easily from our homepage in the top left corner under the heading, "Register for an account on our new site." Once registered, you can visit our forums by going up to the menu bar at the top of the homepage and moving your cursor over the Resources option, then clicking on Discussion Forums which is the second item down.
Dive Encounter by Todd Fulks -
"There I was at the end of our dive in just a few inches of water near shore, when I noticed a brilliant bright green fish with red hues on its lower jaw and streaking down its belly. It was sitting near a textbook example of a hairy blenny. I’d been told the males can have brilliant colors when mating so I knew I’d stumbled upon something interesting. As I looked around, I found two more drab olive green females. The girls were just blah-looking in comparison to the clownish colorations of the male hairy blenny. I lurched in the surf a bit as I watched a female slip up against a rock next to the brightly colored male. She jittered and shook violently. Then the male convulsed a few times and shook his body as he finned the underside of the rock. The female flitted a few feet away and the male convulsed again and then jolted to a new perch. The surge was such that I wasn’t able to look under the rock without causing damage so I’m not sure exactly what I witnessed. I’ll have to defer to the experts. Perhaps this was a courtship dance, perhaps they were actually breeding, or maybe egg care by proud parents. Or it could have been something else entirely… I mean it is Carnival time here in Bonaire and I’ve seen some guys wearing strange colorful costumes recently. None of the blennies left the two foot area the entire time and I was able to show all of them to two giddy divers that barely had room on their slates for the 100+ species we saw on the dive. I was determined to catch a good photo of the male, but it was tricky. He was more elusive and shy than the females and moved around frequently. Finally he settled between some rocks and one of his partners nuzzled in close and they posed. ‘Click.’"

Following the most recent Indo-Pacific Lionfish expedition at Stuart Cove’s in Nassau, Bahamas, we kicked off the next phase of our critical research on this invasive species in Eleuthera. Supporters, Trish and David Ferguson, served as hosts for the week. Earlier this summer, REEF staff set up 11 study sites, tagging 30 fish on six different patch reef and clearing the other 5 sites of lionfish. This past week, I revisited those tagging sites and documented any movement of lionfish. We then following up with early morning, mid-day and evening activity observations to see what the fish were up to and when. The observations involved pre-sun up dives and 2-3 hour bottom times. With some very early and late dive times, the data collected is showing interesting patterns of low light activity.
After five days of intense data collecting at the Ferguson’s we headed down to Cape Eleuthera to meet with staff and students at the Island School and Cape Eleuthera Institute(CEI). The facility is completely self contained, producing their own electricity via solar and wind, their own biodiesel, raising cobia and tilapia in an aquaculture facility and even growing their own hydroponic vegetables. A very impressive operation and an incredible group of staff and students. We were able to conduct collecting and dissecting demonstrations for the coral research class and then do a packed house talk to all of the staff and students from TIS as well as a number from the local Deep Creek Middle School. There is strong interest in collaborating on future lionfish studies as well as incorporating fish surveys into the regular research curriculum at the IS and CEI. Look for future REEF projects to be scheduled here in 2009. Visit our Lionfish Research page for more information.
Last Friday, May 15th, America celebrated Endangered Species Day. While very few marine species have technically been declared as endangered, many of the critters that REEF volunteers see while conducting marine life surveys have experienced declines in recent years. REEF programs and data provide much needed information for scientists and resource agencies charged with evaluating the status of such species. A recent example is a National Marine Fisheries Service (NMFS) proposal to list 5 species of rockfish in the Puget Sound under the Endangered Species Act (ESA). The status review was just published on April 22 and REEF data were extensively used in the assessment. This example highlights the value of REEF data as a fisheries-independent data source; such information is critical for those species that are too rare to be targeted for harvest. A copy of the assessment is posted online.
The Nassau grouper, which is the focal species of REEF’s Grouper Moon Project, has been classified as endangered under the IUCN’s Red List. The Grouper Moon Project is a collaborative conservation program between REEF and the Cayman Islands Department of the Environment to study one of the last known large Nassau grouper spawning aggregations in the Caribbean. Grouper Moon Project lead scientist, Dr. Brice Semmens, will be presenting the ground-breaking findings of this research during a special one day session to be held in the Ocean Hall at the Smithsonian’s National Museum of Natural History this Wednesday, May 20th. "Beyond the Obituaries: Success Stories in Ocean Conservation" will feature some of the good news coming out of work being conducted in the oceans. Brice’s talk, along with all of the success stories, will be webcast online. The Grouper Moon talk is scheduled in the Coral Reef session, which is from 2-3:25.

Long-time REEF supporters, Les and Keri Wilk of ReefNet, recently discovered and photographed a distinctively marked population of the Greenbanded Goby, Elacatinus multifasciatus, on the island of Utila, Honduras. The population was distinguished by a prominent red stripe across the cheek that is not found on other populations of Greenbanded Gobies, as well as more numerous green bars on the body. The Wilks contacted Dr. Benjamin Victor (coralreeffish.com), a reef fish taxonomic expert, who conducted a regional genetic comparison of Greenbanded Gobies to evaluate hidden diversity within this colorful reef fish. As part of the study, the REEF database was used to document the current geographic range of the species. Dr. Victor's results identified the unique looking fish to be a separate species that is now called the Redcheek Goby (E. rubrigenis). He also discovered that, based on genetic results, Greenbanded Goby along coastal Panama, despite looking just like others in the species complex (i.e. a cryptic species, distinguished mainly by differing DNA sequences), are a distinct species that will now be called Panamanian Greenbanded Goby (E. panamensis). The study was published last month in the Journal of the Ocean Science Foundation.
The new species, the Redcheek Goby, replaces the Greenbanded Goby on the island of Utila and has not been sighted at any other location, potentially one of the smallest ranges reported for a Caribbean reef fish. With few exceptions, coral reef fishes have pelagic larvae that spend weeks to months developing in off-reef waters. As a result of this high dispersal ability, most Western Atlantic reef fish species have geographic ranges throughout the Caribbean Sea and adjacent areas. Endemic marine species (those only found in a given region or location and nowhere else in the world) are generally uncommon in the western Atlantic region. Furthermore, many of these widespread species show little, if any, variation in their genetic patterns between areas, particularly within the bounds of the Caribbean Sea with its many stepping-stone islands. Nevertheless, some groups of fishes, presumably those with more-restricted larval dispersal and strong local selection, show interesting patterns of endemism, genetic structure, and cryptic speciation within the region, for example among the Elacatinus cleaning gobies (e.g. Sharknose, Cleaning, Neon, Yellowline, etc.). Those reef fish taxa that contain cryptic species can provide valuable insights into the processes of speciation and the biogeographic history of the region, but also seriously challenge the traditional species concept. The results of Benjamin Victor's study highlight these challenges.
REEF is proud to be able to contribute to scientific studies such as this one. We are also thrilled that fishwatching by amateur non-scientists like our Fish Survey Project volunteers has been elevated beyond just a hobby, and is increasing the state of knowledge about reef fish diversity.

Field Surveys – Eighteen REEF members joined Drs. Christy and Brice Semmens earlier this month on a Field Survey to the Sea of Cortez aboard the Rocio del Mar live-aboard. The team conducted over 300 surveys in 20 locations around the Midriff Islands, many of which were new to the REEF database. It was a great trip, with 130 species of fish found, beautiful topside scenery, and pods of sperm and pilot whales! Find out more about REEF Trips.
Lionfish Derby – The second of three lionfish round-ups in the Florida Keys was held last week off Marathon (FL). During this one-day event, several teams participated to collect this voracious predator off local reefs. The third derby is scheduled for November 13 in Key West.
