Researchers identified a critical nurse shark mating ground in Windlass Bight, Anegada, following 12 days of observations in June 2025. Drone footage and acoustic tagging confirmed the site as a key habitat for the species.
Why it matters
Understanding these mating grounds is vital for the conservation of nurse sharks, whose populations have declined by an estimated 30 to 49 percent over three generations. The shallow waters allow female sharks to navigate away from unwanted mating attempts.
The study area spans 12 acres of shallow sand-and-seagrass flats. Researchers recorded 22 mating attempts over 12 days, including 18 gripping and positioning efforts and two successful copulations.
The players
Environmental Biology of Fishes
This peer-reviewed academic journal publishes research on the ecology, behavior, and conservation of fish species.
The details
The study utilized drone surveillance to monitor behavior from 8:00 a.m. to 5:30 p.m. daily. Researchers also tagged 23 mature nurse sharks with acoustic transmitters to track their return behaviors, supported by historical video evidence from 2018 through 2023.
Timeline
Evidence of nurse shark activity was recorded in videos from 2018 through 2023.
A field team conducted 12 days of focused shark observation in June 2025.
Culture Shift
This discovery updates the known geographical range of shark breeding behavior compared to the Dry Tortugas mating ground. It signals a shift toward better protection for shallow-water habitats as scientists work to understand how these areas sustain vulnerable populations.
The findings highlight the ecological importance of shallow sand-and-seagrass flats in the British Virgin Islands. Residents and visitors in the area should respect these sensitive habitats to help protect vulnerable shark populations.
The takeaway
Protecting specific environmental niches is essential for the survival of species facing long-term population decline. Conserving these shallow coastal areas ensures that marine life can continue to reproduce without unnecessary external disruption.
