Devil ray fact sheet

Mobula tarapacana Sicklefin devil ray 


The sicklefin devil ray (also known as box ray and Chilean devil ray)  is a species that we know very little about.  They are mostly oceanic, but can also be encountered in coastal waters, especially over reefs. Records are scattered, but their range is probably circumglobal in temperate  and tropical waters. They are often solitary, but can also form groups. In the Azores they appear to be fairly common, being encountered frequently by divers and from boats. Their longevity is unkown, nor do we know the details of their reproductive cycle and length of gestation. It is known that they produce only one pup per gestation. Like other rays and sharks, devil rays are ovoviviparous, meaning that they give birth to live young but the eggs are retained inside  the mother´s body until they are ready to hatch.  The main threats to this species are fishing bycatch and direct catches for use of their gill rakers.
