Global distribution of Manta and Mobula rays - A citizen science project based upon a survey of divers

OBIS Canada Open in mapper Explore occurrences

A 'local knowledge' citizen science project based upon a survey of divers. Given that mobulids attract recreational divers and the value of diver-derived data for describing broad trends in coastal biodiversity, we developed a focused online survey to gather information on the spatial and temporal trends and human use patterns of mobulids worldwide. The ‘eManta Survey’ was designed to collect the observations of experienced divers at a 10-degree latitude by 10-degree longitude cell resolution on a global scale.
