  • Renowned manatee scientist Jim Reid places a satellite tag on a pregnant manatee (Trichechus manatus latirostris) named Gina in the Bahamas

  • Researchers Ian Bouyoucos and Cam Raguse test whether a lemon shark pup (Negaprion brevirostris) had been previously tagged at the Cape Eleuthera Insitute in The Bahamas. Lemon shark pups spend the first 5-8 years of their life in mangrove forests. The tangle of roots provides protection from predators like large sharks and is full of potential prey like juvenile fish and crabs. Lemon sharks are the first species of shark proven to practice natal philopatry where the mother will return to the same area she was born in to give birth. Mangroves are being lost at unsustainable rates thanks to coastal development.

  • Marine biologist Dr. Heather Masonjones tags a seahorse, Hippocampus erectus, to study an alkaline pond's population. Through this method of injecting a non-toxic dye, that can only be seen under ultra-violet light, she proved that this pond in The Bahamas has the highest density of seahorses on Earth.

  • Researchers Ian Bouyoucos and Cameron Raguse check if this lemon shark pup has been tagged. If it has been tagged the yellow scanner will pick up a rice-sized (PIT) tag near the base of the dorsal fin and give them a number identifying the shark. If it is a new shark a tag will be implanted.
    Scientific Discovery
  • Dr. Krista Sherman brings a Nassau grouper to the depth the fish was originally caught at. The fish was implanted with a permanent tag that will transmit the fish's location for the rest of his or her life. Blood and a fin clip were also taken for genetic analysis.
    Release
  • Scientists from the Cape Eleuthera Institute catch a green sea turtle (Chelonia mydas), take samples, tag and release her. The long-term study is to determine best practices for turtle conservation.

  • Researcher Hailey Davies uses her cell phone to photograph a juvenile yelloweye rockfish (Sebastes ruberrimus) before tagging and then descending the fish back to the deep as part of a study on rockfish barotrauma. Vancouver Island, British Columbia, Canada.

  • A lemon shark pup is caught in a mangrove creek in south Eleuthera, Bahamas. At less than 2 feet he is a very young shark. He will be transported to a lab and then to an open-ocean pen for observation before being released as a tagged, wild shark. The shark will become a representative of the species. Lemon sharks depend on mangroves for the survival of the first 5-8 years of their lives. Mangroves are disappearing throughout the world and the fate of the lemon shark is left in the balance. We need to get proper protections for the world's mangroves and then enforce them.

  • A fisherman's cage is pulled up by researchers. It is illegal to fish for Nassau grouper (Epinephelus striatus) December - February in the Bahamas when this image was taken. Lack of enforcement is a common issue in Bahamian fisheries. The scientists tagged and released the fish. It is part of an ongoing study to learn about the amazing phenomenon known as the grouper spawning aggregation. During the winter full moons the normally solitary grouper gather en masse to spawn at certain locations throughout the Caribbean and are especially vulnerable to over-fishing. Learning about these aggregations is of major importance to protect and manage the economically and culturally important fishery for these critically endangered fish.

    Illegal Fishing
  • Dr. Krista Sherman collects a Nassau Grouper from an onboard livewell in The Bahamas to be tagged, measured and examined.
    Tracking Grouper
  • A tiny lemon shark pup is enclosed in a seine net. The shark is captured to be studied, tagged and released back into the wild. Lemon sharks depend on mangroves for the survival of the first 5-8 years of their lives. Mangroves are disappearing throughout the world and the fate of the lemon shark is left in the balance. We need to get proper protections for the world's mangroves and then enforce them.
