Abstract: We were studied the venom apparatus of two marine cone snails, specimens of
Conus coronatus and
Conus frigidus were collected from the Coast of Qeshm Island, Persian Gulf. After dissection, the venom apparatus were fixed in Bouin's fixative, for the histological purposes. The venom bulb is a muscular organ which, located in the middle part of a channel with epithelial cells that secreted some material. Venom duct walls consists the outer layer of connective tissue with muscle, an inner layer of columnar epithelial cells with basal nucleus and the inner lumens with the departed nucleus. The distal portion of the venom duct displayed fewer granules than the proximal in both species. Although Holocrine secretion was find in the whole venom apparatus, but venom bulb had a weak secretion role. The venom duct near the pharynx probably had a more mature granule than the other part.
