The Faces of REEF: Dennis Bensen, 2021 REEF Volunteer of the Year

Author: Christy Pattengill-Semmens, Ph.D., Co-Executive Director: Science & Engagement

We are excited to honor Dennis Bensen as 2021 REEF Volunteer of the Year. Dennis joined REEF in 2001, and quickly became an avid REEF surveyor as part of the Volunteer Fish Survey Project (VFSP). Through the years, he has earned Expert level surveyor status in both Hawaii (HAW) and the Tropical Western Atlantic (TWA) survey regions, and he is one of the few surveyors who has conducted REEF surveys in most (7) of REEF’s 10 survey regions worldwide. After living in New York for decades, Dennis moved to the Big Island of Hawaii when he retired in 2015. This move enabled him to be in the water often, and he has a weekly “Ohana” survey dive with many of his local REEF friends. In 2021, Dennis achieved a long-time goal of becoming a Golden Hamlet, when he submitted his 1,000th survey. He currently has 1,109 surveys in the REEF database. He also frequently attends REEF Field Survey Trips, having gone on 28 trips over the last two decades!

In addition to his contributions to the REEF database, he is a standout VFSP ambassador who regularly introduces new volunteers to the program. He even co-taught a REEF Fishinar about eels of Hawaii in 2021. Dennis is strongly committed to REEF’s mission and is a proud member of the REEF Legacy Society, joining others who have included REEF in their estate plans. Thank you Dennis, for your two decades of service to the organization! It’s an honor to recognize you as our 2021 Volunteer of the Year! To read more about Dennis, you can check out his Golden Hamlet Club profile here.

An Action Packed Month of Spawning and Research With the Grouper Moon Project

Author: Christy Pattengill-Semmens, Ph.D., Co-Executive Director: Science & Engagement

Our Grouper Moon Project team returned to the Cayman Islands around the full moon in February for another month of research on the Nassau Grouper spawning aggregation on the west end of Little Cayman. Because this year was a "split moon" year, we weren't quite sure whether the major spawning activity would happen in January or February. While a few thousand fish showed up at the spawning aggregation in January, there was no spawning activity - but the fish made up for it in February. Many thousands of Nassau Grouper were present at the site, with spawning starting just two days after the full moon - the earliest our team has even documented it! Because the fish do not stay at the aggregation site longer than three or four days after they start spawning, the team worked hard to get our annual monitoring done in the condensed time the fish were present. Our team documented populations and fish sizes, and collected eggs from the spawn to conduct water temperature experiments. This was the 20th year of the Grouper Moon Project, a collaborative conservation science effort between REEF and the Cayman Islands Department of Environment, with help from Scripps Institution of Oceanography and Oregon State University, and many local businesses including Southern Cross Club, Peter Hillenbrand, Little Cayman Beach Resort, and Reef Divers. To learn more, see amazing underwater footage of the Nassau Grouper aggregation, and read about what makes this project a blueprint for conservation success in the Caribbean, visit www.REEF.org/groupermoonproject.

Be on the Lookout - Regal Demoiselle Expanding its Range in the Tropical Western Atlantic

Author: Amy Lee, Engagement and Communications Manager

Attention REEF surveyors: keep an eye out for the non-native Regal Demoiselle while surveying in the Tropical Western Atlantic (TWA) region. The Regal Demoiselle, Neopomacentrus cyanomos, is a damselfish native to a wide area of the Indo-Pacific and Red Sea. First reported as an exotic species in the Gulf of Mexico in 2016, recent reports show that the Regal Demoiselle has expanded its non-native range to southeast Florida. The species was reported in the Florida Keys in 2020 and has since moved up Florida's east coast to Blue Heron Bridge near West Palm Beach, where it was reported by a REEF member and surveyor in February. Through a collaborative effort with a team at the United States Geological Survey and Phillip and Patricia Frost Museum of Science, the Regal Demoiselle was quickly located and captured alive, operating under a Special Activity License from Florida Fish and Wildlife Conservation Commission. The fish is now in quarantine and will soon be on display in the non-native species exhibit at the Frost Museum.

Similar in appearance to the native Brown Chromis, the Regal Demoiselle is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill cover, and yellow or pale rear margins on 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. For more information about the Regal Demoiselle, check out this page, which includes a helpful table showing how to tell the difference between it and the native Brown Chromis.

Experts think that the Regal Demoiselle was introduced into the TWA by hitchhiking on oil and gas platforms relocated from their native range. Some experts also believe that the Regal Demoiselle has the potential to place mild competitive pressure on native fishes. It is important to track the spread of the Regal Demoiselle to understand the impacts it may have on native species and habitats. If you see the Regal Demoiselle while doing a REEF survey, be sure to report it by entering it under the "unlisted species" section. Please also report detailed information on the sighting to REEF through the Exotic Species Sighting Form.

Fish of the Month: March 2022

Author: The REEF Team

The brightly colored and feisty Garibaldi (Hypsypops rubicundus) is our March Fish of the Month!

Survey Regions: Garibaldis are found in subtropical waters of California, part of REEF's PAC region, and can also be seen on the west coast of Baja California, which is part of the Tropical Eastern Pacific (TEP) survey region. You can view the Garibaldi distribution reports from the REEF database here: PAC region and TEP region

Size: They are the largest members of the Damselfish family, growing up to 15 inches.

Identifying Features: Garibaldis have a uniform bright orange body with a heart-shaped tail. As juveniles, they are covered with electric blue spots, which disappear with age.

Fun Facts: Garibaldis inhabit kelp forests and rocky reefs. Adults, especially egg-guarding males, are known to be extremely territorial. In fact, after spawning, the male Garibaldi will chase the female away almost immediately to prevent her from eating the eggs. The Garibaldi is also the state marine fish of California.

Thanks for reading, and stay tuned for our next Fish of the Month.
