The structure of the venom gland of stonefish Synanceja horrida.
The structure of the venom gland of stonefish Synanceja horrida was studied using light microscopy, and transmission and scanning electron microscopy. The glands were covered with a fibrous capsule which divided the glandular tissue into many septa which carried numerous nerves and blood vessels. Transmission electron microscopy showed Type I cells with electron-dense material and tubular cisterns, Type II cells with dilated cisterns, sarcoplasmic reticulum and dense secretory granules. The secretory granules were globular and seen in monomer or polymer form. The secretory cells appear to be unique in comparison with the venom gland cells of snakes, scorpions or spiders.
