Abstract The stonefish has an advanced poisonous gland that has a lumen and medulla consisting of connective tissue types. All authors have studied the poisonous gland of stonefish and they give attention to two types of cells only careless transmission semithin. In the present study, we give attention to the whole structures of this gland by an accurate examination of Electron Micrographs in all gland areas. Also, some authors give attention to secretions only and do not give any attention to the complete structure of the poisonous defense system of an animal. In the present study, the sections were taken in different areas as the front gland, and mid, surround the spine for covering all areas to discover any new structure. This study revealed that the stonefish poisonous gland Synanceia verrucosa in the Red Sea has four types of cells called T.A, T.B, T.C, and T.D appear as (first evidence) in semithin only.
