This study employs three key methodologies: the use of baited remote underwater video systems (BRUVs), environmental DNA (eDNA) extraction, and satellite tagging of Spine Tail Devil Rays. BRUVs involve a metal structure with a camera on one end and bait on the other to study the abundance and diversity of marine carnivorous species.

eDNA, obtained by filtering water samples from various depths and locations, allows for the detection of species without direct contact, making it especially useful for identifying scarce populations. The tagging of devil rays is conducted underwater using a rod propelled by elastic bands to implant satellite tags, ensuring the rays are neither captured nor immobilized. The Shark Med team, with extensive technical, logistical, and scientific expertise across multiple countries, collaborates with organizations like Save the Med, forming a robust, multidisciplinary group capable of executing complex marine conservation projects such as this.
