Bull-nosed ray is a large fish with a width of more than 2 meters between the pectoral fins. It is famous for the long-distance migration of large groups. In the Atlantic, the ox-nosed ray usually migrates north in late spring and back south after autumn. In the Gulf of Mexico region, flocks of migrating ox-nosed rays can reach more than 10,000 at the most, swimming clockwise from western Florida towards the Gulf of Mexico near the Yucatan Peninsula.

The migration time of the bull-nosed ray can be up to 2 years.
