(d) Mushroom Shaped Gland or Utricular Gland: The junction of two vasa deferentia and ejaculatory duct in 6 th and 7 th abdominal segments is surrounded by an accessory reproductive gland called mushroom shaped gland or utricular gland. Sperms are glued together to form bundles called spermatophores. This is called mosaic vision.
