Our annual Cozumel trip is known for its many unique fish finds, including the Cozumel-endemic Splendid Toadfish as well as high concentrations of other interesting species like Cherubfish, Blackcap Basslets, and Sargassum Triggerfish. When not diving, you will enjoy all the wonderful food and culture that Mexico has to offer, as well as daily fish ID classes. Reserve your spot today because this popular trip is sure to sell out quickly!
As REEF continues to grow in scope and scale, our leadership must grow along with it. Last year, the Board of Trustees made the strategic decision to expand from nine to eleven members to better support our mission. We are thrilled to announce that Dr. Julia Parrish and Will Ribbens officially joined the Board on January 1, 2026.
Both Julia and Will bring a wealth of expertise, a passion for citizen science, and a deep-rooted love for the marine environment. Please join us in welcoming them to the REEF family!

Join us for the expedition of a lifetime. Explore Halmahera and northern Raja Ampat on the largest wooden liveaboard dive boat in Southeast Asia. Indonesia is the centre of the famous Coral Triangle and is a place every diver has on their bucket list. It is recognised for its extraordinary diversity of coral species, marine life, and the most extensive and richest reefs in the world. Every dive offers amazing new sights, from majestic manta rays and numerous species of sharks to endemic species and critters.
Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long-term, representative information on key fish populations and habitats to inform management and policy. Underwater fish observation techniques, such as Underwater Visual Census (UVC - which includes the REEF Volunteer Fish Survey Project), stereo-Baited Remote Underwater Video (stereo-BRUV), and Remotely Operated Vehicles (ROVs), all play a key role in sustaining long-term data collection.
Borneo is shared by Brunei, Malaysia, and Indonesia, is the third-largest island in the world and offers some of the best marine life encounters on Earth. Living up to Arenui’s motto of being “The Boutique Liveaboard”, attention has been given to every aspect of the Arenui to ensure that it fully embodies their philosophy of providing a unique dive experience. They aim to provide the best there is in terms of diving and leisure activities, without sacrificing any of the comforts and luxury you would expect to get from a 5-star hotel on land.
Join us for a FREE marine life education class at the Trans World Radio (TWR) Bonaire Headquarters on Thursday, February 26 at 7:00 pm AST!
This month’s session, "Lookalikes: Spot the Difference," will focus on those species of reef fish that seem almost identical but have key differences once you know what to look for.
What to Expect:
From walls adorned with spectacular corals, wrecks that are home to a diverse array of marine life, or shallow reefs teeming with tropical fish species, the dive sites of Grand Cayman will delight REEF surveyors. Participants may take advantage of the unlimited shore diving directly in front of Sunset House. While Grand Cayman has hundreds of dive sites, this destination also has plenty of activities to enjoy during surface intervals or to entertain non-divers, including Stingray City, Pedro St.
St. Vincent is known as the muck diving capital of the Caribbean. That doesn't mean that the water is always silty though - the leeward shore of the island typically has visibility up to 100 feet due to the presence of volcanic, granite-based sand that falls quickly when stirred. Surveyors hunting for "bucket list" fish species are in luck; the staff at Dive St. Vincent have a knack for finding small, cryptic species like frogfish, seahorses and more. The island has dramatic topside topography as well, making it a scenic location to enjoy during surface intervals.
This REEF Lionfish Collection & Handling Workshop include a classroom portion that covers invasion history, lionfish biology, ecological impacts, current research and collection techniques. Once wrapping up on land, you have the option to put your skills to work during a two-tank lionfish removal dive that is been run by Key Dives in the afternoon.
Located on a secluded key in Roatan, Honduras, CoCo View Resort is well known among divers for its excellent house reef. Guests will enjoy two daily boat trips and unlimited shore diving at CoCo View’s front yard reef, where more than 300 fish species have been recorded. Fish enthusiasts will be delighted to search for high diversity, found in the Bay Islands. The resort is an excellent fit for non-diving companions as well, who may enjoy front-yard snorkeling and access to ocean kayaks.
