Ray fishes have spines on their whip-like tails. In this study, histological survey was
undertaken to explore venom secretory cells in spines of the 3 species of ray fish in the
Persian Gulf and Oman Sea. Separated spines were preserved in formalin to transfer them to
the laboratory, and spines were dip in EDTA 4%, for decalcification and in the end part,
histological study were done. Results showed that venom secretory cells occurred in cow-tail
stingray (P. sephen) but no venom secretory cell was found in brown eagle ray (A. flagellum)
and butterfly ray (G. poecilura) species. This suggest that layers covering spine is similar to
common covering structure of fishe body.
