Okamejei panayensis is a demersal fish belonging to the skate family, occurring in nearshore temperate environments and deep-water tropical and boreal regions.

[2] This area is on a continental ridge, with muddy sediment, inland bays and wide tidal flats where other Rajidae species are known to reside and spawn.

[2] The ventral surface of the disk is broadly white, with a pale brown margin, and it is darkly pigmented at the bases of the pectoral fins and the nasal curtain.

[2] Pelagic food sources such as squid, krill, shrimp, crustaceans, shelled mollusks, and other benthic invertebrates are typically eaten by demersal elasmobranchs like O. panayensis, indicating that this species likely has an equivalent diet.

However, most Rajidae species are susceptible to overfishing due to their low reproductive rate and a direct relationship between stock size and recruitment.
