Scientists have made a groundbreaking discovery of the rare roughskin dogfish in the Cayman Islands, marking the first documented sighting in this region and the central Caribbean.

This achievement was made possible through the area's first systematic deep-sea biodiversity survey, which employed a baited camera at a depth of 3,500 feet.

The researchers captured high-quality footage of the elusive shark, which swam by the camera 54 times over several minutes, providing valuable visual data.

This noninvasive method underscores the significance of video technology in studying deep-sea species, helping to improve understanding and support conservation efforts.

Documenting species like the roughskin dogfish is crucial for biodiversity preservation and maintaining healthy ecosystems, as emphasized by scientific communities.
