OVERVIEW
The distribution of Munk’s pygmy devil rays (Mobula munkiana) is limited to coastal waters of the Eastern Pacific Ocean from the Sea of Cortez (Mexico) to Peru. This species is often found in extremely large aggregations of up to tens of thousands of individuals at certain times of the year in the Sea of Cortez. While aggregated, Munk’s pygmy devil rays are known to breach regularly, often leaping several metres out of the water. Reasons for this behaviour are still unknown, but possibly linked to social dynamics.
Their typical schooling habits make them particularly vulnerable to demersal and pelagic gill nets as well as trawl and purse seine net fisheries.
