ANGELSHARK-ID: Photo-identification

The Common Angelshark or Monkfish (Squatina squatina)


ANGELSHARK-ID: photo-identification of angelsharks - ElasmoCan


ANGELSHARK-ID is a project that monitors the angelshark (Squatina squatina) in its natural environment. This study uses photo-identification as a tool to identify individuals and guarantee a minimal impact to them.


This research provides scientific base knowledge that contributes to the understanding of the activities that angelsharks develop in the Canary Islands for their survival. Simultaneously it allows to determine their population status and to detect possible threats. The obtained results help to develop an effective species management and to provide a tool to minimize possible impacts to their populations by sharing this information with the public.

How is ANGELSHARK-ID done?

Recognition of distinctive natural body marks for identification of angelsharks (ANGELSHARK-ID)Angelsharks generally present unique natural body marks that allow us to individually identify specimen. This method guarantees minimal impact to the studied individual in return of a great effort from the researcher.

We can reveal different aspects of the species life strategy by identifying the individuals and their characteristics, as the activities that they develop, estimate the number of individuals, how much time can they remain in a location or if they have preference for a certain type of habitat.
