description Spinetail Mobula Overview
The spinetail mobula (*Mobula japanica*), also known as the spinetail devil ray, is a large pelagic fish distributed across tropical and subtropical oceans worldwide. It belongs to the Mobulidae family and is characterized by its dark dorsal coloration, a wingspan that can exceed three meters, and a distinct, serrated spine located at the base of its tail. As a filter feeder, this ray swims with its mouth wide open to consume significant quantities of zooplankton and small schooling fish. It is typically observed by marine biologists and divers in open-ocean environments rather than coastal reefs.

help Spinetail Mobula FAQ
How large can a spinetail mobula ray's wingspan get?
The spinetail mobula (*Mobula japanica*) is a large pelagic ray whose wingspan can exceed 3 meters (about 10 feet). Despite its impressive size, it remains generally smaller than the giant oceanic manta ray, which can reach wingspans of up to 7 meters.
Is the spinetail devil ray the same species as the spinetail mobula?
Yes—both common names refer to the same species, *Mobula japanica*, which belongs to the Mobulidae family. That family encompasses all manta and devil rays, all of which are filter feeders.
Where in the world do spinetail mobula rays live?
The spinetail mobula is distributed across tropical and subtropical oceans worldwide. It is a pelagic species, meaning it lives in the open ocean water column rather than on the seafloor.
Are spinetail mobula rays protected under CITES?
All mobulid rays, including the spinetail mobula, are listed under CITES Appendix II, which regulates international trade in their body parts. They also face pressure from targeted fisheries and bycatch, as their gill plates are valued in some traditional medicine markets.
